Population panic: how demography is used for political gain

<div class="theconversation-article-body"> <p>Population is far from the seemingly innocuous and bland topic of “people”. We’re not just talking people. We’re talking the very foundation of society, culture, and economy … and it’s deeply fraught. It’s also an effective political point scorer.</p> <p>Population scrutiny waxes and wanes in Australian populist and political discourse, much like many nations across the globe. <a href="https://theconversation.com/whats-behind-the-dramatic-shift-in-canadian-public-opinion-about-immigration-levels-219193">Canada</a>, <a href="https://theconversation.com/biden-defends-immigration-policy-during-state-of-the-union-blaming-republicans-in-congress-for-refusing-to-act-225158">the United States</a>, <a href="https://theconversation.com/a-far-right-political-group-is-gaining-popularity-in-germany-but-so-too-are-protests-against-it-223151">Germany</a>, <a href="https://theconversation.com/in-demand-but-disempowered-why-low-skilled-migrant-workers-face-even-worse-exploitation-under-nzs-new-rules-227993">New Zealand</a> and <a href="https://theconversation.com/uk-taking-back-control-of-its-borders-risks-rolling-back-human-rights-protections-230044">the United Kingdom</a> are all grappling with population issues.</p> <p>But when we talk population, it’s pretty safe to read immigration. It’s immigration that has most of the world talking, because growth for many is dominated by international movements, not local growth.</p> <p>Population growth due to immigration has fed growing fears from some quarters about a <a href="https://www.abc.net.au/religion/five-years-terror-christchurch-mosque-danger-muslim-women/103593682">replacement of the majority dominance</a> – in other words, that white people will no longer be the majority in Australia.</p> <p>Contemporary population debate has been largely ill-informed, lacking nuance and is often detrimental. Rooted in a long history of the way we talk about population, contemporary debate is best understood in context, and with facts.</p> <h2>Population dynamics and change</h2> <p>Population is most simply a <a href="https://population.gov.au/population-topics/topic-population-measurement">bunch of individuals</a> living in a specific place. Sounds boring, I know, but the reality is something much greater.</p> <p>When we start talking about what underpins population – composition, characteristics and change – it becomes clear why population is so political.</p> <p>Populations are comprised of varying characteristics – think age, sex, and geography. Characteristics like the age structure of a population have a direct impact on the workforce and economic wellbeing of a nation. A younger population means more expenditure invested in the young to ensure a strong workforce in the future. This is known as the <a href="https://www.prb.org/wp-content/uploads/2019/11/prb-demographic-dividend-evidence-1.pdf">demographic dividend</a>.</p> <p>An older population age structure, on the other hand, sees more spending on the upper end of the life course – senior people – and pressures on the workforce meeting the economic needs of the nation. This is <a href="https://www.abs.gov.au/ausstats/abs@.nsf/2f762f95845417aeca25706c00834efa/851dece969d9182cca2570ec000a2501!OpenDocument">structural ageing</a>.</p> <p>Australia’s population, like most of the world, is structurally ageing. We’re living longer and <a href="https://blog.id.com.au/2023/population/population-trends/australias-birth-rate-falls-in-2022#:%7E:text=Australia's%20birth%20rate%20has%20been,level">not replacing ourselves</a> through births. Living longer is a mark of technological success and ingenuity, and the same could be said about below-replacement births. But our success has some downsides.</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/DBP0rqgSCm5/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/DBP0rqgSCm5/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank" rel="noopener">A post shared by Australian Bureau of Statistics (@absstats)</a></p> </div> </blockquote> <p>The trouble with below-level births and an ageing population is that the local age structure is not sufficient to meet the <a href="https://treasury.gov.au/intergenerational-report">needs of the workforce</a>. Simply, the local Australian population cannot meet the economic needs of the nation, and this has the potential to see living standards go backwards. Immigration helps offset the adverse consequences of an ageing population.</p> <p>Population change occurs due to births, deaths and migration. Commonly known as the population balancing equation, population growth is expressed as: births minus deaths plus migration.</p> <p>Immigration makes up the majority of population growth in Australia and has done so consistently since <a href="https://www.aihw.gov.au/reports/australias-health/profile-of-australias-population">around 2005</a>, with the exception of international border closures during COVID. Natural increase – the balance of births minus deaths – also contributes to population growth in Australia.</p> <p>However, increasing deaths and declining births means the country is expected to see <a href="https://theconversation.com/eight-charts-on-how-australias-population-is-growing-and-changing-227153">natural decline by 2054</a>.</p> <h2>Population problem</h2> <p>In Australia, there has been a preoccupation with the <a href="https://www.aihw.gov.au/reports/australias-health/profile-of-australias-population">drivers of population change</a> since colonisation. Is the nation’s population <a href="https://digital-classroom.nma.gov.au/defining-moments/postwar-immigration-drive">growing too slowly</a>? <a href="https://www.themandarin.com.au/237985-australia-population-27-million-milestone/">Too fast</a>?

Will migrants <a href="https://www.abc.net.au/news/2021-10-15/migrant-movement-in-australia-covid/100536114">want to come</a> to the country? Are there <a href="https://www.theguardian.com/australia-news/2024/mar/21/migration-numbers-australia-2023-rise">too many migrants</a> coming to Australia?</p> <p>Australia is rarely not in a state of <a href="https://theconversation.com/solving-the-population-problem-through-policy-110970">population panic</a>. Population panic once stemmed from being a small population in a big country vulnerable to external military attack. Now population panic is about the pace of growth being too great, due to immigration.</p> <p>And it doesn’t take much to stoke <a href="https://www.theguardian.com/global-development/2022/oct/18/global-population-growth-8-billion-unfdp-united-nations-warning-alarmism">population fear</a>. Population is charged and offers an easy trigger point to leverage voters. Politicians on all sides of the ideological landscape know this and use population discourse effectively for political gain.</p> <figure><iframe src="https://www.youtube.com/embed/h5CubF42DGI?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Since the <a href="https://www.jstor.org/stable/41110698">early 1900s</a>, Australia’s history has been dotted with inquiries into growth and birth rates. In fact, at the time of colonisation, the male-dominated imbalance in the colony sparked calls for more women from Britain – <a href="https://unsw.press/books/the-future-of-us/">of suitable status</a> – to help arrest high rates of hooliganism, drunkenness, and sexually transmitted infections.</p> <p>Women of standing were believed to help socialise the nation and provide essential children for nation building. Nothing much has changed really, with the Treasurer Jim Chalmers saying in the lead up to the 2024 federal budget: “<a href="https://youtu.be/JLzp53D6thg?si=p8YheMdF0-ndO9DB">It would be better if birth rates were higher</a>”.</p> <h2>So why aren’t women having babies?</h2> <p>Australian federal treasurers have expressed concerns about birth rates over many years, across different governments. Chalmers wasn’t the first and he won’t be the last bemoaning below-replacement births.</p> <p>In 2004, then-treasurer Peter Costello <a href="https://ministers.treasury.gov.au/ministers/peter-costello-1996/transcripts/doorstop-interview-treasury-place-melbourne-16">famously said</a>: “have one for mum, one for dad and one for the country”. <a href="https://www.thenewdaily.com.au/finance/finance-news/2020/07/25/baby-bonus-frydenberg-costello">Josh Frydenberg, while treasurer, stated</a>:</p> <blockquote> <p>I won’t go as far as to say, like Peter Costello, “one for the mother, one for the father and one for the country”. But [what] I can say is that people should feel encouraged about the future and the more children that we have across the country, together with our migration, we will build our population growth and that will be good for the economy.“</p> </blockquote> <p>In the 1940s, Australia held an inquiry into falling birth rates, and following the second world war Australians were called on to populate or perish. During the 1940s inquiry, <a href="https://catalogue.nla.gov.au/catalog/1786445">women were invited to make submissions</a> reflecting how difficult motherhood was and how unsupported they were: "You men in easy chairs say ‘populate or perish’. Well, I have populated and I have perished – with no blankets.”</p> <p>Many Australians now won’t achieve their desired family size because contemporary life is simply not conducive to having children. Having no or fewer children is now a forced outcome for a growing number of Australians. The barriers to having a child are now insurmountable for far too many. Housing affordability, gender inequality, financial insecurity and climate change make for an unstable and uncertain future.</p> <p>Young Australians are carrying the burden of the nation’s future and the burden is simply too much. They have seen the generational bargain crumble and are being denied a future because of the failings of politics past.</p> <h2>Permanent versus net overseas migration</h2> <p>Among the many nuances missing from the population debate is the difference in the terminology used to refer to immigration. From a planning point of view, permanent migration is discussed; from a population perspective, net overseas migration applies. The difference between the two is stark and used in a smoke and mirrors way to hide reality or harm an opponent.</p> <p>Government has much control over permanent migration, little control over net overseas migration.</p> <p>Permanent migration refers to the cap of permanent visas granted. The permanent migration program is reviewed annually by the <a href="https://immi.homeaffairs.gov.au/what-we-do/migration-program-planning-levels">Department of Home Affairs</a> with input from select experts, peak bodies, and government.</p> <p>Permanent migration <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_departments/Parliamentary_Library/Budget/reviews/2023-24/Immigration">has fluctuated over the past ten years</a>, reflecting political point scoring. Under Tony Abbott’s government in 2014-15, permanent migration was just under 190,000. The permanent migration remained in the 180,000s until declining to over 160,000 in 2017-18 under Scott Morrison. Morrison also reduced permanent migration further to around 144,000 in 2021-22. In its final year, the Morrison government flagged increasing the planning level for <a href="https://treasury.gov.au/sites/default/files/2021-06/p2021-182464.pdf">permanent migration to 190,000</a>. Planning levels under the Anthony Albanese government were 195,000 and 190,000 in 2022-23 and 2023-24 respectively.</p> <p>The permanent migration program ceiling is set to decline by 5,000 places to 185,000 in 2024-25 under Albanese.</p> <p>Opposition Leader Peter Dutton has also announced his party would reduce permanent numbers to 140,000, seemingly linking <a href="https://www.liberal.org.au/latest-news/2024/05/16/leader-oppositions-budget-address-reply">housing affordability to permanent migration</a>. Dutton has also said his party would cut net overseas migration (NOM) but has since <a href="https://www.abc.net.au/news/2024-12-08/dutton-walks-back-promise-to-cut-net-migration/10469921">backtracked on his plan</a>, possibly because he realised it couldn’t be done.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Explaining the 2024 Migration Surge</p> <p>A recent surge in net migration has become a hot topic, with politicians &amp; media linking it to housing pressures. </p> <p>But what is Net Migration? </p> <p>And do we really have unusually high volumes of migration? <a href="https://t.co/TjzwbtGqsF">https://t.co/TjzwbtGqsF</a> <a href="https://t.co/aFHXIeC4ay">pic.twitter.com/aFHXIeC4ay</a></p> <p>— Alan Gamlen (@alangamlen) <a href="https://twitter.com/alangamlen/status/1795721881699664286?ref_src=twsrc%5Etfw">May 29, 2024</a></p></blockquote> <p>Net overseas migration feeds into population estimates and is the balance of incoming minus outgoing migration. <a href="https://immi.homeaffairs.gov.au/what-we-do/migration-program-planning-levels?fbclid=PAZXh0bgNhZW0CMTEAAaZPBEWLyQJhkvB8_SaqYBSgRdV_rx4Kjy86bbkugYRsOO2cukAoD2wd5dM_aem_AcfxCup1XXR8DP4ZaRfFTFaXggVYw8b8TyNLWsw-3fIenPm_wsx7xM0zfsZHmQ2OjYi0H-YUQdLxUjQUcT47Feij#:%7E:text=Net%20overseas%20migration%20%E2%80%93%20relationship%20with,New%20Zealanders%20and%20Humanitarian%20migrants">NOM is comprised</a> of temporary and permanent migration and includes refugees, students, working holiday makers, and even Australian and New Zealand citizens.</p> <p>A cut to the permanent migration program is unlikely to affect net overseas migration numbers. NOM is set to return to <a href="https://budget.gov.au/content/bp3/download/bp3_14_appendix_a.pdf">recent historical average</a> even without reduced permanent numbers. Most people granted permanency are <a href="https://immi.homeaffairs.gov.au/what-we-do/migration-program-planning-levels?fbclid=IwZXh0bgNhZW0CMTEAAR1aJLdjyJotVfICnc2Ge8vcrJ6DMCaPC4XfDOST9owl1qS4YfBYCKYPkBw_aem_AcegFZW0_vafT8J90jDFyG8aVhMd2f0Ab_9EqE1Y38Q5vuVT5NExZi5Um2BrkpHg0odl0odbI0pDfnUE7A34PRhi">already in the country</a>. What will occur with a reduced migration program is increased temporariness. Increased temporariness has the potential to erode social cohesion, harming migrants and Australian society overall.</p> <p>Just like births, populist tactics are used when talking immigration for quick political point scoring. It works, but is it good for people?</p> <h2>Turning on ourselves</h2> <p>Demography is often used against the population in a peculiar ploy to win political points.</p> <p>Take gender. Fewer birth means less expenditure on paid parental leave and superannuation for those receiving parental leave. Announcing <a href="https://www.abc.net.au/news/2024-05-14/federal-budget-pledges-superannuation-into-paid-parental-leave/103846312">increased</a> paid parental leave benefits and superannuation while knowing births are set to be fewer is political genius. Chalmers announced exactly this in the 2024 budget.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">BREAKING: Parliament has just passed our bill to expand Paid Parental Leave to 26 weeks. On top of that, we've announced a plan to pay super on PPL from 1 July 2025 - all part of our efforts to ensure women earn more, keep more of what they earn &amp; retire with more as well <a href="https://twitter.com/hashtag/auspol?src=hash&amp;ref_src=twsrc%5Etfw">#auspol</a> <a href="https://t.co/p3p4ib6sed">pic.twitter.com/p3p4ib6sed</a></p> <p>— Jim Chalmers MP (@JEChalmers) <a href="https://twitter.com/JEChalmers/status/1769541268739080507?ref_src=twsrc%5Etfw">March 18, 2024</a></p></blockquote> <p>The government says it’s doing more for women and mothers, but what it’s actually doing is a <a href="https://www.abc.net.au/news/2024-05-20/paid-parental-leave-payments-saving-millions-fertility-rate/103866506">whole lot of nothing</a>. There is no substantive examination of why women are saying no to motherhood. Demographic insights have enabled an effective political sleight of hand to give the illusion of doing something when actually not doing much at all.</p> <p>Blaming population growth for the housing crisis is another stroke of political mastery. Talking tough on population (immigration) while promoting and relying on immigration is a tale as old as Australia’s ageing population. When in opposition the talk is tough; when in government, actions speak louder than words. Governments and oppositions, no matter the political leaning, make promises and then realise immigration is the economic safety raft keep the economy afloat.</p> <p><a href="https://ministers.treasury.gov.au/ministers/jim-chalmers-2022/speeches/budget-speech-2024-25">Chalmers talked tough</a> on immigration in his 2024 budget speech, pointing the finger of blame towards immigration for all manner of things,</p> <blockquote> <p>[…] we’re addressing the pressures caused by population growth, with net overseas migration next year now expected to be half what it was last year.</p> </blockquote> <p>But the government can’t take the credit for lowering NOM – nothing they did lowered the artificially high rates of NOM Australia saw post COVID border reopening. Yes, the Albanese government has introduced changes to <a href="https://www.reuters.com/world/asia-pacific/australia-tightens-student-visa-rules-migration-hits-record-high-2024-03-21/">build integrity</a> into the <a href="https://www.reuters.com/world/asia-pacific/australia-raises-minimum-savings-student-visa-warns-fake-recruitment-2024-05-08/">migration system</a>, but NOM figures were set to decline anyway. It comes down to the way it is calculated.</p> <p>Border closures in Australia saw NOM fall to <a href="https://www.abs.gov.au/statistics/people/population/overseas-migration/2022-23-financial-year">-88,000 in 2020-21</a>. That’s negative nearly 90,000 people.</p> <hr /> <p><iframe id="datawrapper-chart-9amUU" style="border: none;" title="Overseas migration in Australia from 2014 to 2024" src="https://datawrapper.dwcdn.net/9amUU/1/" width="100%" height="426" frameborder="0" scrolling="no" aria-label="Interactive line chart" data-external="1"></iframe></p> <hr /> <p>This was the first such decline outside wartime in Australia’s recorded history. A big deal. Temporary migrants, including students, left Australia prematurely at the onset and peak of COVID-related measures. Morrison, prime minister at the time, told international students and temporary visa holders to “go home”, while saying those with critical skills <a href="https://www.abc.net.au/news/2020-04-03/coronavirus-pm-tells-international-students-time-to-go-to-home/12119568">could stay and contribute</a>: “For those backpackers in Australia who are nurses or doctors, or have other critical skills that can really help us during this crisis, then there will be opportunities for them”. Expendability of migrants echoed in this statement.</p> <p>What happened with the NOM during COVID closed borders was essentially a calculation reset. Higher than expected numbers of people left Australia prematurely. Students, especially, left Australia prior to their studies finishing. This resulted in greater outgoings of NOM than the recent average. NOM restarted the moment borders reopened, but because so many brought forward their exit the number of incomers weren’t balanced by the usual outflow of people.</p> <p>Taking a longer view of NOM prior to and since COVID-related measures shows smoother growth than popular media suggests. But nuance is hard to articulate in small soundbites, especially when the language of otherness is so enticing.</p> <h2>Creating the ‘other’</h2> <p><a href="https://journals.sagepub.com/doi/10.1177/14705958231216936">The language of otherness</a> is used extensively in the population (immigration) narrative. Dutton played population bingo with his use of the word “foreign” in his 2024 budget reply speech referring to students, ending investment, and interference. Dutton also blamed migrants for road congestion and pressure on local services. His speech was a populist symphony.</p> <p>When in opposition, members of the now government also made disparaging comments about migrants. For example, <a href="https://www.smh.com.au/national/do-we-want-migrants-to-return-in-the-same-numbers-the-answer-is-no-20200501-p54p2q.html">Kristina Keneally</a> wrote an opinion piece suggesting migrants were taking jobs from locals.</p> <p>Fear about population is easily manufactured, and once created enables a fix the playmaker can resolve. Much like a David Copperfield magic special. The trouble with these tactics is in the enormous <a href="https://www.abs.gov.au/statistics/people/population/australias-population-country-birth/latest-release">diversity in Australia</a> – we risk turning on ourselves and eroding already fraying social cohesion.</p> <h2>Shaping Australia</h2> <p>Our preoccupation with population largely reflects the central place people and demography hold in the economy and very function of the nation. But we appear to have lost our heads, instead problematising the very heart of what makes us Australian: the people.</p> <p>Demography is a slow-moving train, and based on past and current trends population science can somewhat predict the future. The populist playbook results in population (namely immigration) used for political point scoring, to the detriment of the people, particularly the young.</p> <p>Australia is by no means perfect. There is much work to be done to fix the multiple crises the nation is confronted with – housing affordability, financial insecurity, gender inequality, and climate change. A sensible approach to population and immigration is needed to ensure living standards don’t go backwards. Migrants help us weather the demographic headwinds.</p> <p>Rather than use population for political gain, we need instead to harness the power of demography to solve our way out of the gigantic mess we’re in. The key is ensuring young people have a future worth living.</p> <hr /> <p><em>This is an edited extract from <a href="https://thamesandhudson.com.au/product/how-australian-democracy-works-and-why-we-need-it-more-than-ever/">How Australian Democracy Works</a>, a new collection of essays from The Conversation on all aspects of the country’s political landscape.<!-- Below is The Conversation's page counter tag.

Why do some people’s hair and nails grow quicker than mine?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michelle-moscova-310728">Michelle Moscova</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Throughout recorded history, our hair and nails played an important role in signifying who <a href="https://www.psychiatrictimes.com/view/gender-culture-and-social-constructs-in-body-focused-repetitive-behaviors">we are and our social status</a>. You could say, they separate the caveman from businessman.</p> <p>It was no surprise then that many of us found a new level of appreciation for our hairdressers and nail artists during the COVID lockdowns. Even Taylor Swift reported <a href="https://abcnews.go.com/GMA/Culture/taylor-swift-reveals-shes-cutting-hair-covid-19/story?id=74757540&amp;t">she cut her own hair during lockdown</a>.</p> <p>So, what would happen if all this hair and nail grooming got too much for us and we decided to give it all up. Would our hair and nails just keep on growing?</p> <p>The answer is yes. The hair on our head grows, on average, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">1 centimeter per month</a>, while our fingernails grow an average of just <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11436330/">over 3 millimetres</a>.</p> <p>When left unchecked, our hair and nails can grow to impressive lengths. Aliia Nasyrova, known as the Ukrainian Rapunzel, holds the world record for the longest locks on a living woman, which measure an <a href="https://www.youtube.com/watch?v=1TdlEIQdVwo&amp;t=81s">impressive 257.33 cm</a>.</p> <p>When it comes to record-breaking fingernails, Diana Armstrong from the United States holds that record <a href="https://www.youtube.com/watch?v=nwql937j-7Q">at 1,306.58 cm</a>.</p> <p>Most of us, however, get regular haircuts and trim our nails – some with greater frequency than others. So why do some people’s hair and nails grow more quickly?</p> <h2>Remind me, what are they made out of?</h2> <p>Hair and nails are made mostly from keratin. Both grow from matrix cells below the skin and grow through different patterns of cell division.</p> <p>Nails grow steadily from the matrix cells, which sit under the skin at the base of the nail. These cells divide, pushing the older cells forward. As they grow, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5383514/">the new cells slide</a> along the nail bed – the flat area under the fingernail which looks pink because of its rich blood supply.</p> <p>A hair also starts growing from the matrix cells, eventually forming the visible part of the hair – the shaft. The hair shaft grows from a root that sits under the skin and is wrapped in a sac known as the hair follicle.</p> <p>This sac has a nerve supply (which is why it hurts to pull out a hair), oil-producing glands that lubricate the hair and a tiny muscle that <a href="https://www.ncbi.nlm.nih.gov/books/NBK546248/">makes your hair stand up</a> when it’s cold.</p> <p>At the follicle’s base is the hair bulb, which contains the all-important hair papilla that supplies blood to the follicle.</p> <p>Matrix cells near the papilla divide to produce new hair cells, which then harden and form the hair shaft. As the new hair cells are made, the hair is pushed up above the skin <a href="https://www.jidonline.org/article/S0022-202X(15)41553-2/fulltext">and the hair grows</a>.</p> <p>But the papilla also plays an integral part in regulating hair growth cycles, as it sends signals to the stem cells to move to the base of the follicle and form a hair matrix. Matrix cells then get signals to divide and start a new growth phase.</p> <h2>Unlike nails, our hair grows in cycles</h2> <p>Scientists have identified <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">four phases of hair growth</a>, the:</p> <ol> <li> <p>anagen or growth phase, which lasts between two and eight years</p> </li> <li> <p>catagen or transition phase, when growth slows down, lasting around two weeks</p> </li> <li> <p>telogen or resting phase, when there is no growth at all. This usually lasts two to three months</p> </li> <li> <p>exogen or shedding phase, when the hair falls out and is replaced by the new hair growing from the same follicle. This starts the process all over again.</p> </li> </ol> <figure class="align-center "><img src="https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=308&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=308&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=308&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=387&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=387&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/637402/original/file-20241210-15-gtv259.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=387&amp;fit=crop&amp;dpr=3 2262w" alt="Stages of hair growth graphic" /><figcaption><span class="caption">Hair follicles enter these phases at different times so we’re not left bald.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/stages-hair-growth-cycle-vector-isolated-2433656865">Mosterpiece/Shutterstock</a></span></figcaption></figure> <p>Each follicle goes through this cycle <a href="https://www.longdom.org/open-access/a-note-on-the-human-hair-follicle-from-the-origin-to-the-death-93871.html?t">10–30 times in its lifespan</a>.</p> <p>If all of our hair follicles grew at the same rate and entered the same phases simultaneously, there would be times when we would all be bald. That doesn’t usually happen: at any given time, only one in ten hairs is in the resting phase.</p> <p>While we lose about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">100–150 hairs daily</a>, the average person has <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">100,000 hairs</a> on their head, so we barely notice this natural shedding.</p> <h2>So what affects the speed of growth?</h2> <p>Genetics is the most significant factor. While hair growth rates vary between individuals, they tend to be <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4201279/">consistent among family members</a>.</p> <p>Nails are also influenced by genetics, as siblings, especially identical twins, tend to have <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-319-26594-0_121-1">similar nail growth rates</a>.</p> <p>But there are also other influences.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">Age makes a difference</a> to hair and <a href="https://link.springer.com/referenceworkentry/10.1007/978-3-319-26594-0_121-1">nail</a> growth, even in healthy people. Younger people generally have faster growth rates because of the slowing metabolism and cell division that comes with ageing.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">Hormonal changes</a> can have an impact. Pregnancy often <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">accelerates</a> hair and nail growth rates, while menopause and high levels of the stress hormone cortisol can <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">slow growth rates</a>.</p> <p>Nutrition also changes <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6380979/">hair</a> and <a href="https://ijdvl.com/nails-in-nutritional-deficiencies/?t">nail</a> strength and growth rate. While hair and nails are made mostly of keratin, they also contain water, fats and various minerals. As hair and nails keep growing, these minerals need to be replaced.</p> <p>That’s why a balanced diet that includes sufficient nutrients to support your hair and nails is essential for maintaining their health.</p> <p>Nutrient deficiencies may contribute to hair loss and nail breakage by disrupting their growth cycle or weakening their structure. Iron and zinc deficiencies, for example, have both been linked to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6380979/">hair loss</a> and <a href="https://ijdvl.com/nails-in-nutritional-deficiencies/?t">brittle nails</a>.</p> <p>This may explain why thick hair and strong, well-groomed nails have long been associated with perception of good health and high status.</p> <p>However, not all perceptions are true.</p> <h2>No, hair and nails don’t grow after death</h2> <p>A persistent myth that may relate to <a href="https://www.britannica.com/topic/vampire">the legends of vampires</a> is that hair and nails continue to grow after we die.</p> <p>In reality, they only <em>appear</em> to do so. As the body dehydrates after death, the skin shrinks, making hair and nails <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2151163/">seem longer</a>.</p> <p>Morticians are well aware of this phenomenon and some <a href="https://www.adomonline.com/mortuary-man-reveals-how-he-handles-nails-of-the-dead/?t">inject tissue filler</a> into the deceased’s fingertips to minimise this effect.</p> <p>So, it seems that living or dead, there is no escape from the never-ending task of caring for our hair and nails.<!-- Below is The Conversation's page counter tag.

Australians are having fewer babies and our local-born population is about to shrink: here’s why it’s not that scary

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/amanda-davies-201009">Amanda Davies</a>, <em><a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a></em></p> <p>Australians are having fewer babies, so many fewer that without international migration our population would be on track to decline in just over a decade.</p> <p>In most circumstances, the number of babies per woman that a population needs to sustain itself – the so-called <a href="https://www.who.int/data/gho/indicator-metadata-registry/imr-details/123">total fertility rate</a> – is 2.1.</p> <p>Australia’s total fertility rate dipped below 2.1 in the late 1970s, moved back up towards it in the late 2000s (assisted in part by an improving economy, better access to childcare and the introduction of the <a href="https://theconversation.com/what-the-baby-bonus-boost-looks-like-across-ten-years-81563">Commonwealth Baby Bonus</a>), and then plunged again, hitting a low of <a href="https://www.abs.gov.au/statistics/people/population/population-projections-australia/2022-base-2071#assumptions">1.59</a> during the first year of COVID.</p> <hr /> <p><iframe id="CHdqj" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/CHdqj/3/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>The latest population projections from the Australian Bureau of Statistics assume the rate remains near its present 1.6% for <a href="https://www.abs.gov.au/statistics/people/population/population-projections-australia/2022-base-2071#assumptions">the next 50 years</a>.</p> <p>An alternative, lower, set of assumptions has the rate falling to 1.45 over the next five years and staying there. A higher set of assumptions has it rebounding to 1.75 and staying there.</p> <p>A comprehensive study of global fertility trends published in March in the medical journal <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)00550-6/fulltext#%20">The Lancet</a> has Australia’s central case at 1.45, followed by a fall to 1.33 by the end of the century.</p> <p>Significantly, none of these assumptions envisages a return to replacement rate.</p> <p>The bureau’s central projection has Australia’s population turning down from 2037 in the absence of a boost from migration.</p> <hr /> <p><iframe id="oi55c" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/oi55c/3/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>It’s easy to make guesses about reasons. Reliable contraception has been widely available for 50 years. Rents, mortgages and the other costs facing Australians of child-bearing age appear to be climbing. It’s still <a href="https://www.abc.net.au/news/2023-12-17/career-or-baby-michelle-battersby-pregnancy-gender-/103186296">difficult to have a career</a> if you have a child, and data show women still carry the substantive burden of <a href="https://theconversation.com/mind-the-gap-gender-differences-in-time-use-narrowing-but-slowly-191678">unpaid work around the home</a>.</p> <p>The US fertility rate has fallen <a href="https://ourworldindata.org/grapher/children-per-woman-un?tab=chart&amp;time=1950..latest&amp;country=OWID_WRL%7EUSA%7EAUS">much in line with Australia’s</a>.</p> <p>Reporting on <a href="https://theconversation.com/us-birth-rates-are-at-record-lows-even-though-the-number-of-kids-most-americans-say-they-want-has-held-steady-197270">research</a> into the reasons, Forbes Magazine succinctly said a broken economy had “<a href="https://fortune.com/2023/01/12/millennials-broken-economy-delay-children-birthrate/">screwed over</a>” Americans considering having children.</p> <p>More diplomatically, it said Americans saw parenthood as “<a href="https://fortune.com/2023/01/12/millennials-broken-economy-delay-children-birthrate/">harder to manage</a>” than they might have in the past.</p> <h2>Half the world is unable to replace itself</h2> <p>But this trend is widespread. The <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)00550-6/fulltext#%20">Lancet study</a> finds more than half of the world’s countries have a fertility rate below replacement level.</p> <p><a href="https://theconversation.com/chinas-population-shrinks-again-and-could-more-than-halve-heres-what-that-means-220667">China</a>, which is important for the global fertility rate because it makes up such a large share of the world’s population, had a fertility rate as high as 7.5 in the early 1960s. It fell to 2.5 before the start of China’s <a href="https://www.scmp.com/economy/china-economy/article/3135510/chinas-one-child-policy-what-was-it-and-what-impact-did-it">one-child</a> policy in the early 1990s, and then slid further from 1.8 to 1 after the policy was abandoned in 2016.</p> <hr /> <p><iframe id="idC4X" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/idC4X/3/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>South Korea’s fertility rate has dived further, to the world’s lowest: <a href="https://time.com/6488894/south-korea-low-fertility-rate-trend-decline/">0.72</a>.</p> <p>The fertility rate in India, which is now <a href="https://www.un.org/development/desa/dpad/publication/un-desa-policy-brief-no-153-india-overtakes-china-as-the-worlds-most-populous-country/">more populous than China</a>, has also fallen <a href="https://data.worldbank.org/indicator/SP.DYN.TFRT.IN?page=&amp;locations=IN">below replacement level</a>.</p> <p>Most of the 94 nations that continue to have above-replacement fertility rates are in North Africa, the Middle East and Sub-Saharan Africa. Some, including Samoa and Papua New Guinea, are in the Pacific.</p> <p>Most of Asia, Europe and Oceania is already below replacement rate.</p> <h2>A changing world order</h2> <p>The largest high-fertility African nation, <a href="https://www.weforum.org/agenda/2020/09/the-world-population-in-2100-by-country/">Nigeria</a>, is expected to overtake China to become the world’s second-most-populous nation by the end of the century.</p> <p>But even Nigeria’s fertility rate will sink. The Lancet projections have it sliding from 4.7 to <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)00550-6/fulltext#%20">1.87</a> by the end of the century.</p> <p>The differences mean the world’s population growth will increasingly take place in countries that are among the most vulnerable to environmental and economic hardship.</p> <p>Already economically disadvantaged, these nations will need to provide jobs, housing, healthcare and services for rapidly growing populations at a time when the rest of the world does not.</p> <p>On the other hand, those nations will be blessed with young people. They will be an increasingly valuable resource as other nations face the challenges of an ageing population and declining workforce.</p> <h2>An older world, then a smaller world</h2> <p>Global fertility <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)00550-6/fulltext">halved</a> between 1950 and 2021, shrinking from 4.84 to 2.23.</p> <p>The latest projections have it sinking below the replacement rate to somewhere between 1.59 and 2.08 by 2050, and then to between <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)00550-6/fulltext">1.25 and 1.96</a> by 2100.</p> <p>The world has already seen peak births and peak primary-school-aged children.</p> <p>In <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)00550-6/fulltext">2016</a>, the world welcomed about 142 million live babies, and since then the number born each year has fallen. By 2021, it was about 129 million.</p> <p>The global school-age population aged 6 to 11 years peaked at around 820 million in <a href="https://www.un.org/development/desa/dpad/publication/un-desa-policy-brief-no-152-population-education-and-sustainable-development-interlinkages-and-select-policy-implications/">2023</a>.</p> <p>The United Nations expects the world’s population to peak at 10.6 billion in <a href="https://www.smh.com.au/national/the-planet-s-population-will-get-to-10-4-billion-then-drop-here-s-when-we-reach-peak-human-20231213-p5er8g.html">2086</a>, after which it will begin to fall.</p> <p>Another forecast, produced as part of the impressive <a href="https://www.healthdata.org/research-analysis/gbd">Global Burden of Disease</a> study, has the peak occurring two decades earlier in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30677-2/fulltext">2064</a>, with the world’s population peaking at 9.73 billion.</p> <h2>Fewer babies are a sign of success</h2> <p>In many ways, a smaller world is to be welcomed.</p> <p>The concern common <a href="https://theconversation.com/a-long-fuse-the-population-bomb-is-still-ticking-50-years-after-its-publication-96090">in the 1960s and 1970s</a> that the world’s population was growing faster and faster and the world would soon be unable to feed itself has turned out to be misplaced.</p> <p>Aside from occasional blips (China’s birth rate in the <a href="https://www.jstor.org/stable/1973601">Year of the Dragon</a>) the fertility trend in just about every nation on Earth is downwards.</p> <p>The world’s population hasn’t been growing rapidly for long. Before 1700 it grew by only about <a href="https://ourworldindata.org/population-growth-over-time">0.4% per year</a>. By 2100 it will have stabilised and started to fall, limiting the period of unusually rapid growth to four centuries.</p> <p>In an important way, lower birth rates can be seen as a sign of success. The richer a society becomes and the more it is able to look after its seniors, the less important it becomes for each couple to have children to care for them in old age. This is a long-established theory with a name: the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4116081/">demographic transition</a>.</p> <p>For Australia, even with forecast immigration, lower fertility will mean changes.</p> <p>The government’s 2023 <a href="https://treasury.gov.au/publication/2023-intergenerational-report">Intergenerational Report</a> says that whereas there are now 3.7 Australians of traditional working age for each Australian aged 65 and over, by 2063 there will only be 2.6.</p> <p>It will mean those 2.6 people will have to work smarter, perhaps with greater assistance from artificial intelligence.</p> <p>Unless they decide to have more babies, which history suggests they won’t.<!-- Below is The Conversation's page counter tag.

<p>An analysis of the world's sexual habits has revealed the top 10 most promiscuous countries in the world and Turkey came in first. </p> <p>The average Turk has slept with more than 14 people according to the World Population Review, with Australia coming in a close second with the average Aussie having slept with more than 13 people, according to the <em>New York Post</em>. </p> <p>“The average number of sexual partners can vary significantly from country to country, as cultural norms can have a significant impact on the number of people someone has sex with,” the website declared. </p> <p>Their figures were based on a compilation of “datasets from multiple third party sources.”</p> <p>Turkey's top spot may be surprising to some, with most residents being muslim and the country is widely conceived to have traditional views when it comes sex and relationships. </p> <p>New Zealand came in at third, with a similar number to Australia,  followed by Iceland and South Africa. </p> <p>Countries thought to have more liberal views on sex, such as Brazil and France, were lower down the list, with the average Brazilian sleeping with nine people putting them in 25th place, while France clocked in 29th position. </p> <p>The United States clocked in 13th place, with Americans sleeping with an average of 10.7 people. </p> <p><strong>Here's the Top 10 most promiscuous countries:</strong></p> <p>1. Turkey (14.5 people)</p> <p>2. Australia (13.3)</p> <p>3. New Zealand (13.2)</p> <p>4. Iceland (13.0)</p> <p>5. South Africa (12.5)</p> <p>6. Finland (12.4)</p> <p>7. Norway (12.1)</p> <p>8.

What is minoxidil, the anti-balding hair growth treatment? Here’s what the science says

<p><a href="https://theconversation.com/profiles/jacinta-l-johnson-1441348">Jacinta L. Johnson</a>, <em><a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em> and <a href="https://theconversation.com/profiles/kirsten-staff-1494356">Kirsten Staff</a>, <em><a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Hair loss (also known as alopecia) often affects the scalp but can occur anywhere on the body. It’s very common and usually nothing to worry about; about <a href="https://www.sciencedirect.com/science/article/pii/S0022202X15525840">half of Australian men</a> show signs of visible baldness at age 50 and <a href="https://www.sciencedirect.com/science/article/pii/S0022202X15525840">over a quarter of Australian women</a> report hair thinning by the same age. It’s often genetic.</p> <p>But if you’ve noticed hair loss and are worried by it, see a GP or dermatologist for a diagnosis before trying any treatments. Products claiming to reverse hair loss are everywhere, but few have been scientifically tested for how well they work.</p> <p>One group of products that have actually been scientifically tested, however, are known as topical minoxidil products. These include products such as Regaine®.</p> <p>So, do they work? Here’s what the research evidence says, what you can realistically expect and what you need to know if you’re considering this treatment.</p> <h2>What is minoxidil – and does it work?</h2> <p>Topical minoxidil usually comes as a kind of foam or serum you apply to your scalp.</p> <p>It’s been approved by the <a href="https://www.tga.gov.au/">Therapeutic Goods Administration</a>, Australia’s regulatory authority for therapeutic goods, for the treatment of hereditary hair loss in males and females. Minoxidil is also available in tablet form, but this isn’t currently approved for hair loss (more on that later).</p> <p>So, is topical minoxidil effective? In short – yes, but the results vary widely from person to person, and it needs to be used consistently over several months to see results.</p> <p>Scientists don’t know exactly how minoxidil works. It may affect the different phases of the hair life cycle, thereby encouraging growth. It also <a href="https://www.tandfonline.com/doi/full/10.1080/09546634.2021.1945527?casa_token=KhIM_u0u8nwAAAAA:5njp_XE5cHhip454ycvU1p9p_t0VVzpjRu0ozDZ9YqNb04fmhmngWzYeiowZcG5UugLQkTVIzCcj7A">opens up blood vessels</a> near hair follicles.</p> <p>This increases blood flow, which in turn delivers more oxygen and nutrients to the hair.</p> <p>While minoxidil is unlikely to restore a full head of thick, lush, hair, it can slow down hair loss and can <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD007628.pub4/full?highlightAbstract=minoxidil">stimulate regrowth</a>.</p> <p>It is the over-the-counter option with the most evidence. Two strengths are available: 5% and 2%.</p> <p>An analysis of randomised controlled trials found minoxidil applied to the scalp twice a day increased the number of hairs per square centimetre by <a href="https://pubmed.ncbi.nlm.nih.gov/28396101/">eight to 15 hairs</a>, with the higher strength treatment having a slightly greater effect.</p> <h2>Can I use it for non-genetic balding?</h2> <p>There are many causes of hair loss. The main cause in both males and females is a hereditary condition called androgenic alopecia.</p> <p>Although topical minoxidil is only approved for use in Australia for androgenic alopecia, there is some evidence it can also help in other conditions that cause hair loss.</p> <p>For example, it may hasten hair regrowth in patients who have lost hair due to <a href="https://www.jaad.org/article/S0190-9622(96)90500-9/abstract">chemotherapy</a>.</p> <p>Unfortunately, minoxidil is not effective when the hair follicle is gone, like after a burn injury.</p> <p>Although small studies have found promising results using minoxidil to promote hair growth on the face (for <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/1346-8138.13312">beard</a> or <a href="https://pubmed.ncbi.nlm.nih.gov/24471459/">eyebrow</a> enhancement), topical minoxidil products are not currently approved for this use. More research is required.</p> <h2>What else do I need to know?</h2> <p>Minoxidil won’t work well for everyone. Early in treatment you might notice a temporary increase in <a href="https://pubmed.ncbi.nlm.nih.gov/22409453/">hair shedding</a>, as it alters the hair cycle to make way for new growth. Minoxidil needs to be trialled for three to six months to determine if it’s effective.</p> <p>And as it doesn’t cure hair loss, you must <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jdv.14624?casa_token=P-zW7kDNRs8AAAAA%3AaUgUzxU7lbwBpg1BYPajOfXFhpb_mU5g_ounZ6GtjsLLkHO_AdVQ2Kf-8zZkW80ykBj3N_sOsyn392uc">continue</a> to use it each day to maintain the effect. If you stop, you will start losing the new hair growth <a href="https://www.nps.org.au/assets/medicines/1f8127a5-2a98-4013-a7c3-a53300feb0e5-reduced.pdf">within three to four months</a>.</p> <p>Minoxidil products may not be suitable for everyone. If you have any medical conditions or take any medications, you should speak with your doctor or pharmacist before using minoxidil products.</p> <p>It has not been tested for safety in <a href="https://www.nps.org.au/assets/medicines/1f8127a5-2a98-4013-a7c3-a53300feb0e5-reduced.pdf">people under 18, over 65, or those who are pregnant</a>.</p> <p>You can read the <a href="https://www.nps.org.au/medicine-finder/regaine-for-men-regular-strength-application">consumer medicines information sheet</a> for more information about using over-the-counter minoxidil products.</p> <p>Many people do not like to use minoxidil solution or foams long-term because they need to be applied everyday day, which can be inconvenient. Or they may notice side effects, such as scalp irritation and changes to hair texture.</p> <p>Some people <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jdv.14624?casa_token=P-zW7kDNRs8AAAAA%3AaUgUzxU7lbwBpg1BYPajOfXFhpb_mU5g_ounZ6GtjsLLkHO_AdVQ2Kf-8zZkW80ykBj3N_sOsyn392uc">tolerate the foam products better</a> than the solution, as the solution contains more of a compound called propylene glycol (which can irritate the skin).</p> <h2>What about the oral tablet form of minoxidil?</h2> <p>Minoxidil is also available on prescription as an oral tablet. While traditionally used for high blood pressure, it has also been used as a treatment for hair loss.</p> <p>In 2020, a <a href="https://www.jaad.org/article/S0190-9622(20)32109-5/abstract">systematic review</a> identified 17 studies involving 634 patients using oral minoxidil for various hair loss conditions.</p> <p>The authors found oral minoxidil was effective and generally well tolerated in healthy people who were having trouble using the topical products.</p> <p>The review noted oral minoxidil may increase hair growth over the whole body and may cause heart-related side effects in some patients. More research is required.</p> <p>In Australia, oral minoxidil is available under the trade name <a href="https://www.nps.org.au/assets/medicines/df29e16f-6464-4652-ba1f-a53300fed275.pdf">Loniten</a>®. However, it is currently only approved for use in high blood pressure.</p> <p>When people seek a prescription treatment for a non-approved purpose, this is called “off-label” prescribing. Off-label prescribing of oral minoxidil, potentially for use in alopecia, may have contributed to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10170338/">shortages</a> of Loniten® tablets in recent years. This can reduce availability of this medicine for people who need it for high blood pressure.<!-- Below is The Conversation's page counter tag.

Australia's life expectancy altered by Covid wave

<p>Australia’s life expectancy took a plunge during the Omicron wave in 2022.</p> <p>According to new data, it has been revealed that Omicron was the cause for a 17% spike in deaths.</p> <p>Nearly 130,000 people died during the first eight months of 2022 - 13.2% higher than the same period in 2021, and 17% above the historical average.</p> <p>At least 7700 of those deaths were doctor-certified as being caused by Covid19, six times higher than during the entirety of 2021.</p> <p>The majority of the spike in deaths in 2022 are attributable to the “challenge” of an ageing population. This includes dementia and heart conditions, as the proportion of people aged over 65 continues to grow.</p> <p>The increase in deaths between 2021 to 2023 has resulted in a temporary drop in life expectancies, however that’s expected to gradually increase over coming years. It will reach 87 for women and 83.5 for men by 2033.</p> <p>Treasury’s latest Annual Population Statement reveals as the proportion of Australians over the age of 65 grows, so does the burden on younger workers.</p> <p>The report found that the share of those over the retirement age will grow from 16.8% in 2020-21 to 19.9% in 2032-33 before reaching 23.1% in 2060-61.</p> <p>That’s set to be combined with a declining fertility rate, projected to decline from 1.66 babies per woman in 2021–22 to 1.62 babies by 2030–31.</p> <p>As a result, the median age will balloon from 38.4 years old in 2020-21 to 40.1 in 2032-33. It was 36.9 in 2008-09.</p> <p>The ageing population is driven by increasing life expectancies and falling fertility rates, with the wave of older Australians created by a large baby boomer generation.</p> <p><em>Image: Getty</em></p>

How to receive criticism with grace and open arms

<p><em><strong>Tom Cronin is a meditation teacher, life coach and writer. He is the founder of The Stillness Project, a global movement that aims to help people on their journey towards calmness and fulfilment.</strong></em></p> <p>Put your hand up if you like to receive criticism.</p> <p>Of course you kept your hand down. No one likes to be criticised. To the point where we often hold ourselves back from doing many great things in fear of being criticised.</p> <p>I saw a quote this week by Aristotle:</p> <p>“There is only one way to avoid criticism, say nothing, do nothing, be nothing.”</p> <p>Criticism can cut to the core of our ego. It challenges all the false beliefs that we’ve had about ourselves. We tend to measure ourselves by the perspectives of others and when that perspective becomes negative, then OUCH! It hurts.</p> <p>I’ll let you in on a secret, which is not so secret now. I’m a recovering perfectionist, recovering in that I’ve been in ‘perfectionist rehab’ trying to wean myself off being a perfectionist. One thing about perfectionists is that we love to be perfect…. and what does criticism from others say about our perfectness? That it doesn’t exist! Our illusion becomes shattered and it’s brutally painful.</p> <p>It was for this reason that I held back from writing, speaking, and teaching. I mean what if someone faulted what I did? Heaven forbid! But the compulsion became stronger and it was a tussle between what was the natural flow forward and my ego holding me back in fear. The block was in my ego, so that’s what I had to work on… dissolving that pesky little thing (only it wasn’t little, it was gargantuan!)</p> <p>Through my meditation practice I was able to slowly dissolve the big E and allow my clear fearless expression to shine through. (Mind you it’s not totally dissolved, there is still some there)</p> <p>Sure, I get criticised. It’s going to happen. But now I see criticism as something very constructive. It’s up to you; it can be destructive or constructive. I find it useful market research that helps me refine what I do and become better at it. In fact, only the other day I asked my children to critique me as a parent. I sat them both down and said to them (true story):</p> <p>“Hey kids, so I have never been trained as parent and this is my first time at it. So I may be doing things wrong or things that you don’t like. I’m still learning. I want you to let me know how you’d like me to change as a parent and what you think I could do better?”</p> <p>To which they replied along the lines of:</p> <p>“Nah, we think you’re doing a great job Dad, you don’t need to change anything.”</p> <p>It was a nice to hear but I was seriously looking for some constructive criticism to help me become better at parenting. I used to really struggle receiving criticism, it was a painful experience. But not I welcome it with gratitude. It teaches me to evolve and adapt.</p> <p>But coming back to Mr. Aristotle, and his quote. What would you prefer? Not being criticised and playing the small safe, game or growing, expanding and inspiring others while you expose yourself to potential criticism?  You think Gandhi, Mother Theresa, Jesus, Martin Luther King or Nelson Mandela were never criticised? The choice is yours and you have greatness within you to share with the world. So what are you waiting for?</p> <p>Share with us how you would like to share your gifts with the world in the comments below.</p> <p><em>Written by Tom Cronin.

The world is about to hit eight billion people

<p>The world is expected to have eight billion people living on it by 15 November this year, according to the United Nations. And India will become Earth’s most populated country in 2023.</p> <p>These are among the latest projections <a href="https://www.un.org/development/desa/pd/sites/www.un.org.development.desa.pd/files/wpp2022_summary_of_results.pdf" target="_blank" rel="noreferrer noopener">published</a> by the UN in its World Population Prospects report, which also highlights the rapid decline in global population growth – now at its slowest rate since 1950 – continuing into the second half of the century.</p> <p>“The cumulative effect of lower fertility, if maintained over several decades, could be a more substantial deceleration of global population growth in the second half of the century,” says UN Department of Economic and Social Affairs population division director John Wilmoth.</p> <p>The UN predicts global population could reach a further 8.5 billion by the end of this decade, 9.7 billion by 2050, and peak at 10.4 billion by the end of the century.</p> <p>That’s a reduction of around 300 million people in 2100 from its estimates <a href="https://population.un.org/wpp/Publications/Files/WPP2019_Highlights.pdf" target="_blank" rel="noreferrer noopener">three years ago</a>.</p> <p>It’s still higher than other projections in recent years, suggesting the world population might peak before the end of the century.</p> <p><a href="https://www.thelancet.com/action/showPdf?pii=S0140-6736%2820%2930677-2" target="_blank" rel="noreferrer noopener">Research</a> from the University of Washington, US, published in 2020 predicted that the world population would peak at about 9.73 billion in 2064, observing that increases in female education and access to contraception would see declines in fertility and population growth.</p> <p>That followed a 2018 <a href="https://pure.iiasa.ac.at/id/eprint/15226/1/lutz_et_al_2018_demographic_and_human_capital.pdf" target="_blank" rel="noreferrer noopener">report</a> from the European Commission’s Joint Research Centre that predicted a peak of 9.8 billion between 2070 and 2080, but also suggested rapid social development and education reach in line with sustainable development goals could see a peak of 8.9 billion by 2060.</p> <p>The reason for these different projections comes down to the assumptions researchers make along the way.</p> <p>At the most basic level, explains Associate Professor Gour Dasvarma, from Flinders University in Adelaide, a population projection considers trends in birth and death rates.</p> <p>“Projections are done by extrapolating past trends, long term trends in fertility, mortality and migration for a country population,” he explains. “For the world population, migration doesn’t matter.</p> <p>“One of the things with the projections is that as and when new data become available, people will revise those.</p> <p>“The latest predictions for the UN is that the world’s population will peak at 10.4 billion by 2100 and then it will start declining.</p> <p>“By that time, the trends indicate that fertility in most of the countries of the world will have declined to a sufficiently low level, the ageing of the population will take hold, and the so-called momentum of population growth will slow down.”</p> <div class="newsletter-box"> <div id="wpcf7-f6-p197949-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.62 spai-bg-prepared init" action="/people/world-population-eight-billion/#wpcf7-f6-p197949-o1" method="post" novalidate="novalidate" data-status="init"> <p style="display: none !important;"><span class="wpcf7-form-control-wrap referer-page"><input class="wpcf7-form-control wpcf7-text referer-page spai-bg-prepared" name="referer-page" type="hidden" value="https://cosmosmagazine.com/people/" data-value="https://cosmosmagazine.com/people/" aria-invalid="false" /></span></p> <p><!-- Chimpmail extension by Renzo Johnson --></form> </div> </div> <p><strong>What are the world’s population trends?</strong></p> <p>Nations transition through <a href="https://cosmosmagazine.com/people/society/watch-the-human-population-skyrocket-in-200-years/" target="_blank" rel="noreferrer noopener" data-type="URL" data-id="https://cosmosmagazine.com/people/society/watch-the-human-population-skyrocket-in-200-years/">cycles of population growth</a>, stability and decline as their economies develop. From periods of stability with high birth and death rates, populations increase as mortality drops.</p> <p>Over time, fertility rates begin to decline, causing stabilisation in population numbers. It’s only when death rates nudge above births that populations begin to naturally decrease.</p> <p>For nations like those in Europe, North America, Australia and New Zealand, this demographic transition was completed between the pre-industrial era and the mid-20th century – a period of about 200 years.</p> <p>“But after 1950, some developing countries like China, other parts of Southeast Asia […] and also Latin America have done it within 70 years because of the increase of contraceptives and faster decline in fertility,” says Dasvarma.</p> <p>With life expectancy projections increasing, nations in the Global South will continue to see their populations to do likewise.</p> <p>Although more than half of the world’s population lives in East, South-east (29% of global population), Central and Southern Asia (26%), the UN expects these regions along with Latin America, the Caribbean, Europe and Northern America to begin declining before the end of the century.</p> <p>In contrast, sub-Saharan African nations are likely to keep growing through 2100, while the next quarter century will see over half of the world’s population increase come from just eight nations.</p> <p>They include India – which will overtake China to be the world’s most populous nation next year – the Democratic Republic of the Congo, Egypt, Ethiopia, Nigeria, Pakistan, the Philippines and Tanzania.</p> <p><strong>Populations are ageing quickly</strong></p> <p>Two thirds of the world’s population now live in areas where lifetime fertility has dropped below 2.1 births. Long term, that equates to zero population growth: one child to replace each parent in nations with low mortality.</p> <p>COVID-19 has also impacted population data – with a drop in global life expectancy (now 71, down from 72.9 before the pandemic) and short-term decreases in pregnancies and births.</p> <p>But the pandemic’s impact was unevenly distributed around the world. In regions hardest hit by deaths, life expectancy at birth dropped by nearly three years. In contrast Australia and New Zealand saw this indicator increase by more than a year, likely thanks to border closures imposed throughout much of 2020.</p> <p>These decreases in national fertility rates will see populations age further in the coming years.</p> <p>By the century’s midpoint, 16% of the global population is expected to be aged over 65 – the same proportion as people under 12 years of age. It’s prompted the UN to recommend nations with ageing populations invest in social safety nets to meet the needs of older people.</p> <p><!-- Start of tracking content syndication.

Massive house price slowdown as interest rate climbs

7 hacks that will revive almost any plant

<p><strong>1. Look for signs of life</strong></p> <p>If your plant has turned brown and lost some leaves, don’t give up on it just yet. There is hope that you can revive a dead plant if the plant still has a few green leaves and pliable stems – buds are a sure sign too. Melinda Meyers, star and producer of Melinda’s Garden Moment TV and radio segments, says that reviving a plant takes patience (sometimes even years).</p> <p><strong>2. Think about the water</strong></p> <p>Plants that are over-watered appear wilted and may have brown or yellow leaves that make it look dead but with very moist soil. By contrast, if you have forgotten to water your plants,  the leaves will be brown but dried around the edges or curled up. Master gardener, Kristena LaMar, says that if you suspect over-watering is the cause of your plant’s demise, repot your plant in dry dirt. And if your plant is thirsty, water it! However, hold off on fertilising until the plant is in better health. Meyers warns that, “Fertilising a struggling plant can injure the tender roots of a recovering plant.”</p> <p><strong>3. Consider your lighting situation </strong></p> <p>If you recently moved your plant to a new spot, it’s possible it’s no longer getting enough light. Even if you didn’t move it, it’s possible its lighting situation changed. Did you recently buy heavier drapes? Plant a tree outside that’s now blocking the indoor sunlight? Try moving your plant to a sunnier window if it needs a lot of light. (Same goes with a plant that’s now getting too much sun; try a different location in your home.)</p> <p><strong>4. Find a humid spot </strong></p> <p>Plants absorb water through leaves as well as roots. So keep your plant in a humid spot that’s not too sunny and not too dry to help it recover.</p> <p><strong>5. Feed your plant carefully</strong></p> <p>People and pets aren’t the only things in your house that need food; plants can get malnourished, too. (Signs are discoloured leaves or slow or no growth.) Meyers recommends a fertiliser/nutritional supplement. Depending on the nutritional deficiency, providing the nutrition can help the plant recover nearly immediately within days. Other deficiencies may take longer – as in weeks – while others are chronic and may not ever fully recover, although these are rare with houseplants.</p> <p><strong>6. IV for plants </strong></p> <p>Another option for malnourished plants is a water-soluble fertiliser that will slowly release nutrients and is less likely to burn your plant’s roots. Add it to the watering can before watering plants. Only use fertiliser during the time when your plant should be growing. Over-fertilising or using the wrong fertiliser can burn the roots of the plant.</p> <p><strong>7. Compost</strong></p> <p>If you’ve tried everything, and your plant still can’t be revived, it might be time to let go. By composting your plants, the remains can be recycled as nutrient-rich dirt that can help your next houseplant thrive. Don’t beat yourself up – and next time buy a hearty, nearly kill-proof cactus.</p>

Woman "stuck" in the body of a child reveals dating problems

<p>A woman who says she is "stuck" in the body of a child has revealed the extraordinary measures she must take in the dating world. </p> <p>Shauna Rae measures 1.16m in height, making her the average height of an 8-year-old. </p> <p>However, the US woman is actually 22 years of age, and had her growth stunted by chemotherapy when she was young. </p> <p>In an interview with <a rel="noopener" href="https://people.com/tv/tlcs-shauna-rae-recalls-when-she-stopped-growing-at-age-16/" target="_blank">People</a> ahead of the release of her upcoming TV show <em>I am Shauna Rae</em>, Shauna said he has to take extra precautions when it comes to her dating life. </p> <p><span>“I have to have in-person conversations before we even think about going on a date. I have to know how this person reacts in public areas,” she said.</span></p> <p><span>“I have to know if they’re going to be able to deal with all the issues I have, because I can’t date someone unless they can take all of that on. And it’s a lot to ask someone to take on.”</span></p> <p><span>Despite her best efforts to meet her soulmate, Shauna said her "romantic life sucks".</span></p> <p><span>“I think I’ve dated like seven people. I attract creeps, a-holes – you know the typical ‘bad boy picture’ situation – and idiots,” she said.</span></p> <p><span>In the trailer for her new series, Shauna is seen meeting a man for a blind date, with the man thinking he is being pranked when she shows up. </span></p> <p><span>When Shauna was just six-months-old, she was diagnosed with a rare form of brain cancer and underwent chemotherapy treatment. </span></p> <p>“My pituitary gland was rendered almost dormant because of the chemotherapy,” Shauna says in the trailer.</p> <p>“The doctor told me I was done growing. My bones were fused, and my height is three feet and 10 inches (1.16m).”</p> <p>Shauna admitted to People that when she stopped growing at age 16, the revelation was "like a hammer crashing into glass".</p> <p>“It was a very difficult time,” she said.</p> <p>“It probably was the lowest time of my life, because I always imagined that I would be tall.”</p> <p>After spending time devoted to "bettering" herself, Shauna has learned to look on the bright side of life, and has come to terms with her size. </p> <p><span>“Being positive is just the best advice I can give, because at the end of the day, the only person that controls how you feel is yourself,” she said.</span></p> <p><span>Check out the trailer for <em>I Am Shauna Rae</em> here. </span></p> <p><iframe width="560" height="315" src="https://www.youtube.com/embed/s7In-KGxduU" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen=""></iframe></p> <p><em>Image credits: Youtube</em></p>

Least popular Australian baby names in 2021

<p>A new study by McCrindle Research has shown the least popular baby names in Australia for 2021.</p> <p>Names like Remi, Harlow, Hallie, Maeve, Adeline, Molly, Maggie, Delilah, Eliza and Isabel have entered the Top 100 girls’ list.</p> <p>However, other names like Riley, Alexis, Victoria, Madison, Lilly, Chelsea, Indiana and Thea have been kicked out.</p> <p>“Heidi was ranked 78 in 2020 and to see it drop out completely was really interesting,” Ashley Fell, social researcher of Australia’s Top Baby Names 2021 report, told<span> </span><a rel="noopener" href="https://www.news.com.au/lifestyle/parenting/babies/the-15-least-popular-australian-baby-names-in-2021/news-story/385b7ddd80f2021cf849fadd80ea218c" target="_blank"><em>news.com.au</em></a>.</p> <p>Other classic names like Heidi and Victoria have also been removed from the top 100.</p> <p>“Heidi has been a consistent name ranked in the 90s over the last decade but has since left in 2021. It shows Aussies are over it,” she told news.com.au.</p> <p>“Victoria is a bit more of a traditional royal name, but we’ve seen the next generation of royals influence Gen Y parents today (Charlotte, being the top name) and other names like George, Harry and Louis pretty popular in the boys’ list, showing the impact of the next generation of royals.”</p> <p>It appears that the new list of baby names are being replaced with more creative names.</p> <p>“Parents don’t want their child to be among 10 Heidis in a class and that’s one of the reasons we’re seeing such greater variety with new names entering the list," she explained.</p> <p>Boys names weren't forgotten in the research either, with Leonardo, River, Luka, Lewis and Lennox breaking into the Top 100.</p> <p>Unfortunately, this was at the expense of names like Tyler, Jake, Christina, Nate and Aaron.</p> <p>“While only five new boys’ names were added to the Top 100 list, twice as many girls’ names were added (10), and when we look at the most popular names that have emerged in the Top 100 over the last decade, there are three times as many girls’ names that have entered, than boys’ names,” she said.</p>

Aged population set to double by 2050

<p>We regularly hear that Australia has an ageing population, and that has never been more true than right now. By 2050, the number of people aged between 65 to 84 years is expected to more than double, and those over 85 will more than quadruple!<sup>2</sup></p> <p>As a population, Australians are living longer than ever before due to advancements in medical technology and a better awareness of a healthier lifestyle. Compared to a century ago, the average lifespan has increased by around 25 years.<sup>1</sup> Couples are also deciding to have children and retire much later in life.<sup>2</sup></p> <p>So how do these trends impact Life Insurance?</p> <p><strong>Australia’s changing population trend</strong></p> <p>With these segments of Australians over the age of 65 set to expand rapidly over the next 30 years, access to healthcare and supportive services is going to be in more demand, resulting in a substantial expenditure in this area.</p> <p>Most of these medical care costs will fall to the Federal and State Governments, however with such an exponential growth in those ageing figures, their budgets will be spread quite thin.<sup>3</sup> This is one of the reasons why people are electing to take up Life Insurance to financially protect them and their families in the future, should something happen to them.</p> <p><strong>How is this changing life insurance?</strong></p> <p>People are much more vulnerable to illness and risk of death the older they become. The increasing lifespans of Australians is also affecting Life Insurance as people look for a way to protect their families for longer periods of time.</p> <p>This impacts Life Insurance in two main ways:</p> <ul> <li>Life Insurance companies are more inclined to <span><a rel="noopener" href="https://www.nobleoak.com.au/faqs/applications-underwriting/" target="_blank">ask more detailed questions</a></span> in the assessment stage, to ensure that you are covered specifically for the duration you require.</li> <li>With couples having children and retiring later in life, they are raising a family at much older ages.

Is slowing Australia’s population growth really the best way out of this crisis?

<p>After weeks of pressuring the government to do more to support temporary migrants who fall outside the criteria for government support, the opposition took a surprising stance in <a href="https://www.smh.com.au/national/do-we-want-migrants-to-return-in-the-same-numbers-the-answer-is-no-20200501-p54p2q.html">The Age and The Sydney Morning Herald</a> on Sunday.</p> <p>Labor immigration spokesperson Kristina Keneally called for a rethink of our migration program and asked:</p> <p><em>when we restart our migration program, do we want migrants to return to Australia in the same numbers and in the same composition as before the crisis?</em></p> <p>She said Australia’s answer should be “<a href="https://www.smh.com.au/national/do-we-want-migrants-to-return-in-the-same-numbers-the-answer-is-no-20200501-p54p2q.html">no</a>”.</p> <p>To me, as an economist, the answer should be a resounding “yes”.</p> <p>Keneally’s piece covered a lot of ground – in addition to making claims about whether or not permanent migrants take the jobs of local workers (<a href="https://www.ceda.com.au/CEDA/media/General/Publication/PDFs/TemporaryMigrationAppendix.pdf">they don’t</a>) she broached the topic of reconsidering our temporary migration intake and held open the possibility of further lowering our permanent intake.</p> <p>Migration is a complex often convoluted area of policy</p> <p><strong>Temporary migrants can’t just turn up</strong></p> <p>Ms Keneally’s comments imply that coming to Australia as a temporary migrant is easy.</p> <p>As the following (rather long) flowchart indicates, it is anything but.</p> <p>Temporary migration is uncapped: there are no in-principle limits on the number of temporary migrants who can come here. This is by design, so the program can meet the skill needs of our economy at any given time.</p> <p>However, the government has a number of tools it uses to contain the program and target the right skills.</p> <p>Keneally makes the point that the arrival of migrants has made it easier for businesses to ignore local talent.</p> <p>But there are requirements that Australian businesses to tap into the Australian labour market before hiring from overseas.</p> <p>She is right when she says unions and employers and the government should come together to identify looming skill shortages and deliver training and reskilling opportunities to Australian workers so they can fill Australian jobs.</p> <p>But no matter how good our foresight and our education and training systems, we will always have needs for external expertise in areas of emerging importance.</p> <p>Training local workers for projects that suddenly become important can take years, during which those projects would stall.</p> <p><strong>Permanent migrants don’t take Australian’s jobs</strong></p> <p>Keneally says Australia’s migration program has “hurt many Australian workers, contributing to unemployment, underemployment and low wage growth”.</p> <p>Australian research finds this to be untrue.</p> <p>Research I conducted for the <a href="https://www.ceda.com.au/CEDA/media/General/Publication/PDFs/TemporaryMigrationAppendix.pdf">Committee for the Economic Development of Australia</a> updating research coducted by Robert Breunig, Nathan Deutscher and Hang Thi To for the <a href="https://melbourneinstitute.unimelb.edu.au/assets/documents/hilda-bibliography/working-discussion-research-papers/2015/migrant-intake-draft-supplementc-1.pdf">Productivity Commission</a> found that the impact of recent migrants (post 1996) on the employment prospects of Australian-born workers was <a href="https://crawford.anu.edu.au/files/uploads/crawford01_cap_anu_edu_au/2018-05/policy_note_-_immigration.pdf">close to zero</a>.</p> <p>If anything, the impact on wages and labour force participation of locals was <a href="https://www.ceda.com.au/CEDA/media/General/Publication/PDFs/TemporaryMigrationAppendix.pdf">positive</a>.</p> <p><strong>Flexibility gives us an edge</strong></p> <p>Australia’s migration program is the envy of other countries. Indeed, its success has prompted Britain to consider changing its system to an Australian skills-based system <a href="https://www.gov.uk/government/publications/the-uks-future-skills-based-immigration-system">assessed through points</a>.</p> <p>Temporary migration is certain to look very different over the next few years than it has over past few. That’s its purpose – to adapt to changing circumstances.</p> <p>It is difficult to see how a sustained cut in temporary arrivals could assist our recovery.</p> <p>The bridge to the other side of this downturn will depend on migration. It will depend on us continuing to welcome migrants.</p> <p><em>Written by Gabriela D’Souza.

How a ‘growth mindset’ helps us learn

<p>One of the most influential phenomena in education over the last two decades has been that of the “<a href="https://www.theguardian.com/teacher-network/2018/jan/04/research-every-teacher-should-know-growth-mindset">growth mindset</a>”. This refers to the beliefs a student has about various capacities such as their intelligence, their ability in areas such as maths, their personality and creative ability.</p> <p>Proponents of the growth mindset believe these capacities can be developed or “grown” through learning and effort. The alternative perspective is the “fixed mindset”. This assumes these capacities are fixed and unable to be changed.</p> <p>The theory of the growth versus fixed mindset was <a href="http://155.0.32.9:8080/jspui/bitstream/123456789/55/1/Mindset_%20The%20New%20Psychology%20of%20Success.pdf">first proposed</a> in 1998 by American psychologist Carol Dweck and paediatric surgeon Claudia Mueller. It <a href="https://www.ncbi.nlm.nih.gov/pubmed/9686450">grew out of studies</a> they led, in which primary school children were engaged in a task, and then praised either for their existing capacities, such as intelligence, or the effort they invested in the task.</p> <p>Researchers monitored how the students felt, thought and behaved in subsequent more difficult tasks.</p> <p>The students who were praised for their effort were more likely to persist with finding a solution to the task. They were also more likely to seek feedback about how to improve. Those praised for their intelligence were less likely to persist with the more difficult tasks and to seek feedback on how their peers did on the task.</p> <p>These findings led to the inference that a fixed mindset was less conducive to learning than a growth mindset. This notion has a lot of support in cognitive and behavioural science.</p> <p><strong>What’s the evidence?</strong></p> <p>Psychologists <a href="https://www.researchgate.net/profile/Peter_Gollwitzer2/publication/312340264_Mindset_Theory/links/59e77e3baca272e940e0b309/Mindset-Theory.pdf">have been researching</a> the notion of a mindset – a set of assumptions or methods people have, and how these influence motivations or behaviour – for over a century.</p> <p>The growth mindset has its roots in Stanford University psychologist Alan Bandura’s 1970s social learning theory of a <a href="https://www.semanticscholar.org/paper/Self-efficacy%3A-toward-a-unifying-theory-of-change.-Bandura/953070a862df2824b46e7b1057e97badfb31b8c2">positive self-efficacy</a>. This is a person’s belief in their ability to succeed in specific situations or to accomplish a task.</p> <p>The growth mindset is also a re-branding of the 1980-90s study of <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2F0022-0663.80.3.260">achievement orientation</a>. Here, people can adopt either a “mastery orientation” (with the goal of learning more) or a “performance orientation” (with the goal of showing what they know) to achieve an outcome.</p> <p>The idea of the growth mindset is consistent with theories of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2896818/">brain plasiticity</a> (the brain’s ability to change due to experience) and <a href="https://scottbarrykaufman.com/wp-content/uploads/2013/11/Basten-et-al.-2013.pdf">task-positive and task-negative</a> brain network activity (brain networks that are activated during goal-orientated tasks).</p> <p>The growth versus fixed mindset theory is supported by evidence too – both for its predictions of outcomes and its impact in interventions. Studies show students’ <a href="http://www.growthmindsetmaths.com/uploads/2/3/7/7/23776169/mindset_and_math_science_achievement_-_nov_2013.pdf">mindsets influence</a> their maths and science outcomes, their <a href="https://eric.ed.gov/?id=EJ1111638">academic ability</a> and their <a href="https://onlinelibrary.wiley.com/doi/full/10.1348/978185409X402580?casa_token=h8ioC3A2hkAAAAA%3Ac9rJPcLSWmi4NX8_U5wKBn1BKVsc4MQqbid4cQk1CMD4dEaPXC_5L1vKI2QHsn7NbUbbhwO1-8vFYlkb-Q">ability to cope</a> with exams.</p> <p>People with growth mindsets <a href="https://www.sciencedirect.com/science/article/abs/pii/S0272735820300040">are more likely to cope emotionally</a>, while those who don’t view themselves as having the ability to learn and grow are more prone to psychological distress.</p> <p>But the theory has not received universal support. A <a href="http://bahniks.com/files/mindset.pdf">2016 study showed</a> academic achievements of university students were not associated with their growth mindset. This could, in part be due to the way it is understood.</p> <p>People can show different mindsets at different times – a growth or fixed – towards a specific subject or task. <a href="https://hbr.org/2016/01/what-having-a-growth-mindset-actually-means">According to Dweck</a></p> <blockquote> <p>Everyone is actually a mixture of fixed and growth mindsets, and that mixture continually evolves with experience.</p> </blockquote> <p>This suggests the fixed and growth mindsets distinction <a href="https://hbr.org/2016/01/what-having-a-growth-mindset-actually-means">lies on on a continuum</a>. It also suggests the mindset a person adopts at any one time is dynamic and depends on the context.</p> <p><strong>What about teaching a growth mindset?</strong></p> <p>The theory has been evaluated in a range of teaching programs. A <a href="https://www.researchgate.net/publication/323565554_To_What_Extent_and_Under_Which_Circumstances_Are_Growth_Mind-Sets_Important_to_Academic_Achievement_Two_Meta-Analyses">2018 analysis</a> reviewed a number of studies that explored whether interventions that enhanced students’ growth mindsets affected their academic achievements. It found teaching a growth mindset had minimal influence on student outcomes.</p> <p>But in some cases, teaching a growth mindset was effective for students from low socioeconomic backgrounds or those academically at risk.</p> <p>A <a href="https://osf.io/preprints/socarxiv/tsdwy">2017 study</a> found teaching a growth mindset had no effect on student outcomes. In fact, the study found students with a fixed mindset showed higher outcomes. Given the complexity of human understanding and learning processes, the negative findings are not surprising. Dweck and colleagues <a href="https://www.nature.com/articles/s41586-019-1466-y?fbclid=IwAR3eSTiOiVc3v8LARTfGwxTzlSDz4AiAFpLK-jK4VcJr57wI0eO8zyvwkEc">have noted that a school’s context</a> and culture can be responsible for whether the gains made from a growth mindset intervention are sustained.</p> <p>Studies show the <a href="https://www.scirp.org/html/8-6902186_77784.htm#ref37">mindsets of both teachers and parents</a> influence students’ outcomes too. Secondary science students whose teachers had a growth mindset <a href="https://files.eric.ed.gov/fulltext/EJ1045824.pdf">showed higher outcomes</a> than those whose teachers who had a fixed mindset.</p> <p>And a 2010 study showed the <a href="https://rd.springer.com/article/10.1007%2Fs11218-010-9126-y">perceptions primary students</a> had of their potential for improvement were associated with what their teachers’ thought of the children’s academic ability. In another study, children whose parents were <a href="https://www.pnas.org/content/113/43/12111.short">taught to have a growth mindset</a> about their children’s literacy skills, and to act accordingly, had improved outcomes.</p> <p><strong>It exists on a spectrum</strong></p> <p>Mindset theory seems to conflate two separate phenomena, both of which need to be considered in teaching: a person’s actual capacity such as intelligence, and how they think about it.</p> <p>Students should be aware of what they know at any time and value it. They also need to know this may be insufficient, that it can be extended and how to do that. Educators and parents need to ensure their dialogue with their children does not imply the capacity is fixed. The focus of the talk should be on: what you will know more about in five minutes?</p> <p>When I teach, in both schools and university, I encourage students at the end of a teaching session to identify what they know now that they didn’t know earlier. I ask them to explain how their knowledge has changed and the questions they can answer now.</p> <p>In the early stages of a teaching session, I encourage them to infer questions they might expect to be able to answer having learnt the content. These types of activities encourage students to see their knowledge as dynamic and able to be enhanced.<!-- Below is The Conversation's page counter tag.

Economic growth near an end as Treasury talks of prolonged coronavirus downturn

<p>Australia’s three-decade run of near continuous economic growth is set to end, with treasury warning of a hit to growth of “at least” 0.5% in the first quarter of this year, potentially followed by a “prolonged downturn”.</p> <p>If it came to pass, treasury’s preliminary assessment would most likely mean economic growth vanished and went backwards for several quarters, producing what is commonly known as a “<a href="https://www.smh.com.au/politics/federal/the-really-lucky-country-talk-of-recession-as-australia-takes-world-record-20170601-gwiiwl.html">technical recession</a>” – two quarters or more in which income and spending shrink.</p> <p>Providing the <a href="https://treasury.gov.au/speech/opening-statement-march-2020-senate-estimates">assessment</a> to a Senate estimates committee on Thursday morning, treasury secretary Steven Kennedy said the COVID-19 coronavirus would take “at least half a percentage point” from economic growth during the current March quarter and more beyond that.</p> <p>In recent quarters economic growth has been about half a percentage point.</p> <p>Treasury’s preliminary estimate of a hit of at least half a per cent took into account only the direct impacts of the virus on tourism and education, and some exchange rate effects.</p> <p>It did not take into account broader economic effects or the impact of the coronavirus on supply chains.</p> <p>The half a percentage point hit to growth would come on top of a hit of 0.2% from the summer bushfires, most of which would be felt in the March quarter.</p> <p>Dr Kennedy, a former nurse who retrained as an economist, stressed that the impact of the bushfires would extend well beyond the immediate hit to economic growth.</p> <p>“Evidence from past episodes suggest bushfires can lead to long-lasting physical and mental health effects and destroy cultural heritage,” he said.</p> <p>“Research by the University of Melbourne after the Black Saturday bushfires in 2009 found mental health problems continued for three to four years.”</p> <p>The bushfires made clear the increased probability of such events in a world of climate change.</p> <p>“The CSIRO predicts climate change will make bushfires more likely, as fire weather patterns worsen as a result of an increase in weather patterns with hot and dry winds and fuel becoming drier.”</p> <p>Deeper, wider and longer lasting than SARS</p> <p>As of Wednesday there had been 91,868 confirmed COVID-19 cases worldwide and 3,131 deaths, most in China. COVID-19 had spread to 77 countries.</p> <p>When the virus first emerged in China in December, the treasury saw it through the lens of the 2002-04 Severe Acute Respiratory Syndrome (SARS) pandemic.</p> <p>It was now clear COVID-19 would be different.</p> <p><em>The impact of SARS took on a V shape, a relatively contained reduction in activity, mostly in Asia, followed by a quick bounce back.</em></p> <p><em>The economic impact of COVID-19 is likely to be deeper, wider and longer when compared with SARS.</em></p> <p><em>It will create more risk of a prolonged downturn, and fiscal support will be needed to accelerate the recovery of the economy, especially once the health and health management effects of COVID-19 begin to fade.</em></p> <p>The first phase of the economic support package to be delivered next week would target assistance to the businesses and sectors most affected in order to keep people in jobs.</p> <p>After that, support for aggregate demand (overall spending) would become more important.</p> <p> “A very substantial part of the impact is actually confidence among consumers and the business sector because of the uncertainty,” Dr Kennedy said.</p> <p>“Frankly, effective health management will be very important. The economy is actually quite solid. One of the key things will be to to explain to the community how well placed the economy is to manage such a short-term shock.”</p> <p>The shock would last for some time but the economy would “recover on the other side”.</p> <p>Keeping workers employed would be very important.</p> <p><em>Written by Peter Martin.

Public health expert warns coronavirus “could infect 60 per cent of world’s population”

<p>A leading public health expert who spearheaded the fight against SARS has issued a warning, saying that close to 60 per cent of the world’s population could become infected by the coronavirus.</p> <p>Professor Gabriel Leung, chair of public health medicine at Hong Kong University, is an expert on coronavirus epidemics and played a key role during the SARS outbreak in 2002 and 2003.</p> <p>Sitting down with<span> </span><em>60 Minutes</em><span> </span>on Sunday, he said that COVID-19 is “certainly more infective (than SARS), and it’s also very difficult to try to control it”.</p> <p>“The big unknown now is really how big is the iceberg,” he said.</p> <p>There have now been over 106,000 confirmed cases around the world and close to 3,600 deaths since the outbreak began in December, with a mortality rate of around 3.4 per cent.</p> <p>“I don’t know, but I’m suspecting that (there are many more people infected),” he said.</p> <p>“Everybody is susceptible. If you assume that everybody randomly mix with each other, then eventually you will see 40, 50, 60 per cent of the population get infected.”</p> <p>At current mortality rates for COVID-19, that could mean between 45 and 60 million deaths worldwide – in the first wave alone.</p> <p>“We have to prepare for that possibility that there is a second wave,” he said.</p> <p>In Australia, a third person died due to the virus in a hospital overnight, with authorities reporting the total number of cases sitting at 79 as of Sunday evening.</p> <p>Professor Leung said it was likely there were many more undetected cases.</p> <p>“For every death you would expect to see 80 to 100 cases,” he said.</p> <p>“So if you start seeing deaths first before you start picking up large numbers of cases the only conclusion that one can reasonably and scientifically draw is that you hadn’t been testing nearly early enough or extensively enough. Unless you go and test, you’re not going to find.”</p> <p>He said it didn’t appear that any country had been “completely successful at 100 per cent containment and driving back into the wild”.</p> <p>“There is now an emergency going on and what we must do is very rigorous infection control,” he said.</p> <p>“Now is the time to really pull out all the stops, put everything you got into it to fight it. We have to give it the whole-of-government approach. Give it all you got, throw everything at it quick and early and hard. That will buy you sufficient time and if you’re extremely lucky, you might even be able to contain it.”</p>

New technology can help understand the decline in Australian sea lions

<p>Australian sea lions are in trouble. Their population has never recovered from the impact of the commercial sealing that occurred mainly in the 19th century.<span class="attribution"><span class="source"></span></span></p> <p>Currently, the Australian sea lion is a threatened species (listed as <a href="https://www.iucnredlist.org/species/14549/4443172">endangered by the International Union for Conservation of Nature or IUCN)</a> with the population estimated at 10,000 – 12,000. More than 80% of these animals live in the coastal waters of South Australia, where their numbers are estimated to have fallen by more than half over the past 40 years.</p> <p>The sea lions’ survival is threatened by many factors, including bycatch in commercial fisheries, entanglement in marine debris and impacts related to climate change.</p> <p>With time running out, the sea lions’ survival depends on informed management. One important step is to establish a low-risk way of quickly assessing the health of the current population. The results could help us identify how to stop the population declining.</p> <p><strong>Technological insight</strong></p> <p>One common way to get a quick idea of an animal’s health is to assess its body using a measure equivalent to the <a href="https://en.wikipedia.org/wiki/Body_mass_index">body mass index</a> (BMI) for humans, which is calculated from a person’s mass divided by the square of their height. But using a tape measure and scales to obtain the size and mass of Australian sea lions is time consuming, costly and involves risky anaesthesia of endangered animals.</p> <p>With our colleagues Dirk Holman and <a href="http://www.antarctica.gov.au/science/meet-our-scientists/dr-aleks-terauds">Aleks Terauds</a>, we recently developed a technique to non-invasively estimate the body condition of Australian sea lions by using a drone to collect high-resolution photos of sedated sea lions. We then used the photos to digitally reconstruct a 3D model of each animal to estimate its length, width and overall volume – and compared these to physical measurements.</p> <p>The technique, recently published in <a href="https://doi.org/10.1016/j.biocon.2019.108402"><em>Biological Conservation</em></a>, worked better than expected.</p> <p><img src="https://images.theconversation.com/files/303405/original/file-20191125-74599-16xcgmq.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /> <span class="caption">Drone-captured photographs were processed to create 2D mosaics of images and 3D models. These were used to measure area and volume, both of which approximated animal mass.</span> <span class="attribution"><span class="source">J. Hodgson</span></span></p> <p>The measurements were accurate, and we found a strong correlation between the mass of an individual and the area and volume measurements derived from the drone pictures. These are the key ingredients needed to assess sea lion condition without handling animals.</p> <p><strong>Conserving an iconic species</strong></p> <p>While simple body condition measurements have limitations, they are useful for conservation because they provide rapid health insights across a species’ range.</p> <p>Australian sea lions breed at around 80 known sites spanning more than 3,000 km of southern Australian coastline within the <a href="https://theconversation.com/australias-other-reef-is-worth-more-than-10-billion-a-year-but-have-you-heard-of-it-45600">Great Southern Reef</a>.</p> <p>Our technique can be used to study free-ranging animals at colonies across this range, from Kangaroo Island in South Australia to the Houtman Abrolhos Islands in Western Australia, and test for differences in condition.</p> <p><a href="https://images.theconversation.com/files/309600/original/file-20200113-103990-1364qeo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/309600/original/file-20200113-103990-1364qeo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /></a> <span class="caption">3D models of animals measured in the study.</span> <span class="attribution"><span class="source">J. Hodgson</span></span></p> <p>This can give us valuable information about how individual health and colony trends in abundance are related. For example, if a colony is in decline and its members are in poor condition, it could be that factors such as food availability and disease are driving the decline.</p> <p>However, if there is no difference in the condition of animals from declining and recovering colonies, then declines may be due to direct human impacts such as bycatch in commercial fisheries and entanglement in marine debris. We could then target the most likely threats identified using this technique to better understand their impact and how to protect the sea lions against them.</p> <p><img src="https://images.theconversation.com/files/303404/original/file-20191125-74599-kf9j1s.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /> <span class="caption">These two adult male Australian sea lions differed by just 11 cm in length but more than 130 kg in mass.</span> <span class="attribution"><span class="source">J. Hodgson</span></span></p> <p>This technique could be used to complete a population-wide survey of Australian sea lion condition and help ensure the species’ survival. It would build on past mitigation measures which include successfully <a href="https://www.afma.gov.au/sites/default/files/uploads/2014/03/Australian-Sea-Lion-Management-Strategy-2015-v2.0-FINAL.pdf">reducing by-catch from gillnet fishing along the sea floor</a>.</p> <p>It will also complement current initiatives, including a trial to <a href="http://www.doi.org/10.1007/s00436-015-4481-4">control a parasite</a> that may improve <a href="https://sydney.edu.au/news-opinion/news/2019/07/22/saving-our-sea-lions.html">pup survival</a>.</p> <p>Australian sea lions are an icon of Australia’s Great Southern Reef. As an important top-order predator in these coastal waters, they are indicators of ocean health. Understanding and mitigating the causes of their decline will not only help the species recover, but it will also help to ensure the unique coastal ecosystems on which Australian sea lions depend remain intact and functional.<!-- Below is The Conversation's page counter tag.

Australia needs a national crisis plan that covers all natural disasters

<p>Calls are growing for a national bushfire plan, including from former prime minister Malcolm Turnbull, who says they are an issue of <a href="https://www.theguardian.com/australia-news/2019/dec/10/national-security-issue-turnbull-tells-qa-morrison-must-step-up-response-to-bushfire-crisis">national security</a> and the federal government must provide hands-on leadership.</p> <p>It’s true that more people are living in high-risk bushfire areas, emergency services are stretched and the climate is rapidly changing. Future crises are inevitable. We must consider the prospect of a monstrous bushfire season, the likes of which we’ve never seen.</p> <p>But bushfires aren’t the only catastrophe Australia must prepare for. If we are to create a national crisis plan, we must go much further than bushfire planning.</p> <p><strong>Not just bushfires</strong></p> <p>In the decade since Victoria’s Black Saturday fires, <a href="https://theconversation.com/what-has-australia-learned-from-black-saturday-111245">we have improved</a> fire predictions, night-time aerial firefighting, construction codes and emergency warnings. All of these have no doubt saved many lives.</p> <p>There are calls for <a href="https://www.theguardian.com/australia-news/2019/dec/10/scott-morrison-rejects-calls-for-more-help-saying-volunteer-firefighters-want-to-be-there">more resources</a> to fight fires, as part of a coordinated national plan. But few people have proposed an all-encompassing vision of such a plan.</p> <p>For a start, it should not be confined solely to bushfires. <a href="https://www.sciencedirect.com/science/article/pii/S1462901114000999">Far more people die</a> during heatwaves and residential housefires. Tropical cyclones, floods and hail each <a href="https://www.tandfonline.com/doi/full/10.1080/17477891.2019.1609406">cost our economy more</a>.</p> <p>Any plan must provide a strategic vision across these various facets for at least the next ten to 20 years.</p> <p><strong>A national firefighting force?</strong></p> <p>Calls for a <a href="https://www.theguardian.com/australia-news/2019/dec/11/former-fire-and-emergency-chiefs-push-for-national-bushfire-emergency-summit">national firefighting force</a> to supplement existing state resources are fundamentally short-sighted. A national force – quite apart from the level of duplication it would create – would spend much of its time idle.</p> <p>Even during severe fires, such as those now raging, there would be limits to its usefulness. At a certain point, the size and energy of the fires means no amount of firefighting technology will extinguish them all.</p> <p>Research conducted by Risk Frontiers, the Australian National University and Macquarie University through the Bushfire and Natural Hazards Cooperative Research Centre, has focused on better planning and preparedness for catastrophic events.</p> <p>This research concludes it is <a href="https://www.bnhcrc.com.au/research/catastrophic">unrealistic</a> to resource the emergency management sector for rare but truly catastrophic events. It is wildly expensive to remain 100% prepared for the worst-case scenario.</p> <p>Instead of simply scaling up existing arrangements, we need to think differently.</p> <p>Bush firefighting could be improved by innovation and research. Future investments must focus on rapidly detecting and extinguishing ignitions before they spread out of control.</p> <p><strong>Everyone is responsible</strong></p> <p>States and territories are traditionally responsible for emergency management in Australia. But almost by definition, a catastrophic disaster exceeds one’s capacity to cope - inevitably drawing on nationwide resources.</p> <p>This means preparing for catastrophic disasters is everyone’s responsibility.</p> <p>Existing plans allow for assistance across state borders, and between state and federal governments. But there is no national emergency legislation defining the Commonwealth’s role, or assigning responsibility for responding to a truly national disaster.</p> <p>The Australian Defence Force has a well-defined support role in natural disasters, but should not be relied on due to its global commitments.</p> <p>However, resource-sharing between states could benefit from more investment in programs that enable emergency services to work better together.</p> <p>International help in massive emergencies also needs better planning, particularly around timing and integration with local agencies.</p> <p>Non-government organisations, businesses and communities already make valuable contributions, but could play a more central role. We could look to the US, which successfully uses a whole-of-community approach.</p> <p>This might mean emergency services help community organisation provide aid or carry out rescues, rather than do it themselves. These organisations are also best placed to make sure <a href="https://theconversation.com/extreme-weather-makes-homelessness-even-worse-heres-how-we-can-help-82758">vulnerable members of the community</a> are cared for.</p> <p>The most important task is to reduce the risk in the first place. The vast majority of disaster-related spending goes on recovery rather than risk reduction. Calls from the <a href="https://www.pc.gov.au/inquiries/completed/disaster-funding#report">Productivity Commission</a> and the Australian Prudential Regulation Authority (<a href="https://www.preventionweb.net/news/view/67832">APRA</a>) for more disaster mitigation funding have been largely ignored.</p> <p>The federal government’s recent <a href="https://www.homeaffairs.gov.au/emergency/files/national-disaster-risk-reduction-framework.pdf">National Disaster Risk Reduction Framework</a> highlights the need to identify highest-priority disaster risks and mitigation opportunities.</p> <p>This would see priority investments in flood mitigation and strengthening of buildings against cyclones in northern Australia. (This will also help address insurance affordability.)</p> <p>Land-use planning needs to be improved to reduce the chance that future developments are exposed to unreasonable risks.</p> <p>Infrastructure must be constructed to the highest standards and, following a disaster, <a href="https://theconversation.com/moving-grantham-relocating-flood-prone-towns-is-nothing-new-4878">destroyed buildings should be rebuilt away from dangerous areas</a>.</p> <p>Finally, communities have the most critical role. We must understand our local risk and be ready to look after ourselves and each other. Governments at all levels must facilitate this spirit of self-reliance. Local leadership is crucial to any crisis plan and communities need to be involved in its construction.</p> <p>Eastern Australia’s bushfire crisis has triggered emotional arguments for throwing resources at the problem. But planning must be careful and evidenced-based, taking into account the changing face of natural disasters.</p> <p><span><a href="https://theconversation.com/profiles/andrew-gissing-272581"><em>Andrew Gissing</em></a><em>, General Manager, Risk Frontiers, Adjunct Fellow, <a href="http://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> and <a href="https://theconversation.com/profiles/michael-eburn-107766">Michael Eburn</a>, Associate Professor in Law, <a href="http://theconversation.com/institutions/australian-national-university-877">Australian National University</a></em></span></p> <p><em>This article is republished from <a href="http://theconversation.com">The Conversation</a> under a Creative Commons license.

Why economic growth isn't enough to guarantee more prosperous Australia

<p>Despite <a href="https://theconversation.com/vital-signs-sure-economic-growth-is-low-but-think-about-whats-gone-right-122973">28 years</a> of uninterrupted economic growth, future generations of Australians face <a href="https://www.sdgtransformingaustralia.com/#/2788/1276//">being worse off</a> due to <a href="https://www.sdgtransformingaustralia.com/#/1249/2659//">increasing household debt</a>, <a href="https://www.sdgtransformingaustralia.com/#/1252/1347//">cost-of-living pressures</a>, <a href="https://www.sdgtransformingaustralia.com/#/1251/1372//">rising wealth inequality</a>, <a href="https://www.aidr.org.au/media/6682/national-resilience-taskforce-profiling-australias-vulnerability.pdf">climate change impacts</a> and <a href="https://soe.environment.gov.au/key-findings-all">environmental degradation</a>.</p> <p>But our <a href="https://www.nature.com/articles/s41893-019-0409-9">new research</a> finds a fairer, greener and more prosperous Australia is possible – so long as political leaders don’t focus just on economic growth.</p> <h2>Evaluating Australia’s progress by 2030</h2> <p>We modelled four development scenarios for Australia through to 2030:</p> <ul> <li>“Growth at all Costs”, emphasising economic growth</li> <li>“Green Economy”, emphasising environmental outcomes</li> <li>“Inclusive Growth”, emphasising social equality</li> <li>“Sustainability Transition”, balancing economic, social and environmental outcomes.</li> </ul> <p>Each scenario involved different policy and investment settings, particularly around tax and subsidies, government expenditure and private investment.</p> <p>We then evaluated each scenario against the <a href="https://www.un.org/sustainabledevelopment/sustainable-development-goals/">Sustainable Development Goals</a>, an internationally recognised set of targets and indicators that measure national progress in 17 major areas. These include economic growth, poverty, inequality, education, health, clean water and clean energy.</p> <h2>Goals, targets and indicators</h2> <p>Each goal involves multiple targets and indicators. Goal 8, for example, is “Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all”. This involves 10 targets including per capita economic growth, decoupling economic growth from environmental degradation, and protecting labour rights. Each target comes with at least one indicator (for example, the growth rate of real GDP per capita, material consumption per GDP, and the rate of occupational injuries).</p> <p>In all, the 17 goals cover 169 targets. Because Australia has not adopted SDG targets, we chose 52 of those (with about 100 indicators) then modelled Australia’s progress in 2030 using our four scenarios.</p> <p>The graph below shows each scenario’s score (with 0% meaning no progress, 100% target achieved) on each of the 17 goals. We also calculated an average score for each scenario across all goals to aid comparison.</p> <h2>Growth alone is not the answer</h2> <p>Our model projects a business-as-usual approach will achieve progress of about 40% across all goals and targets. The “Growth at all Costs’ scenario scored only slightly better: 42%.</p> <p>Economic growth – defined as an increase in a nation’s production of goods and services – is generally measured by the annual change in real gross domestic product (GDP).</p> <p>Our "Growth at all Costs” scenario involves accelerating economic growth through higher population growth and lower taxes. Net migration is modelled as being 350,000 a year by 2030, with the population reaching just over 30 million. The government’s tax revenue as a proportion of GDP is 10% less than now as a result of lower tax rates.</p> <p>Government spending is about 15% less (as a percentage of GDP), with cuts particularly to health, education and social security, but more spending on transport infrastructure. There are no new measures to tackle greenhouse gas emissions, land degradation or other environmental concerns.</p> <p>In our modelling this scenario increases GDP growth to about 2.6% a year, with low unemployment and declining government debt. But it comes at the expense of income inequality and the environment.</p> <p>Even on the one goal it might be expected to do relatively well – Goal 8 – this scenario performs quite poorly. That’s because the goal measures per capita GDP growth, not just the total GDP growth most politicians talk about, along with a range of social and environmental indicators.</p> <p>The following graphs show how the four scenarios compare on real GDP (i.e. adjusted for inflation), per capita GDP, income inequality and greenhouse gas emissions.</p> <h2>Sustainability transition</h2> <p>With an overall score of 70%, the “Sustainability Transition” scenario is the clear winner.</p> <p>This scenario modelled slower population growth and higher taxes on consumption, income and profits and trade. With net migration of 100,000 a year by 2030, the population reaches about 28 million. Tax revenue as a percentage of GDP is about 8.5% higher than now. This funds more spending on health, education and social security, as well as the equivalent to 1% of GDP on the sustainability of transport, water, energy, agriculture and energy systems.</p> <p>The overall result is economic growth of about 2.1% a year, with government debt 10% higher than our business-as-usual projection.</p> <p>But per capita GDP is higher. Unemployment and income inequality are lower. Fewer people live in relative poverty, and life expectancy is higher. Energy, water and resource consumption is down. So are greenhouse gas emissions. There is more forested land. This delivers a more prosperous, fairer and greener nation in 2030.</p> <h2>Possible futures</h2> <p>These results run contrary to the “growth and jobs” narrative that <a href="https://www.businessinsider.com.au/heres-how-many-times-scott-morrisons-budget-speech-used-the-catchphrase-jobs-and-growth-2016-5">dominates political debate in Australia</a>. Both sides of politics emphasise economic growth as the key to prosperity. But this narrative is clearly flawed when we look at a broader set of issues.</p> <p>The Sustainable Development Goals seek to capture all of these issues in a coherent way. Our study explores four plausible futures, and there are many other possible combinations that could be explored with worse or better results.</p> <p>What is clear is that business as usual certainly won’t ensure Australia has a more prosperous, fairer and environmentally sustainable society.<!-- Below is The Conversation's page counter tag.
