Fertility Collapse a Warning We Can't Ignore

Australia is running out of babies.

That sounds dramatic, but the figures are dramatic. The Australian Bureau of Statistics recorded a total fertility rate of 1.481 children per woman in 2024, the lowest in our history. Replacement level is about 2.1. Commonwealth projections suggest the figure could fall to 1.42 in 2025–26.

For anyone who has not spent their life reading demographic reports, the total fertility rate estimates how many children the average woman would have if the birth rates recorded at each age in that year were maintained throughout her reproductive life. It is not simply a headcount of babies, nor a direct measure of biological infertility.

Australia registered 292,318 births in 2024, up 1.9 percent on the previous year. Yet the fertility rate still fell because the number of women of childbearing age grew faster than the number of births. The median age of mothers was 32.1. For fathers, it was 33.9. So it hardly makes the picture more comforting.

Australia’s fertility rate peaked at 3.55 children per woman in 1961. It dropped below replacement in 1976 and has never climbed back. This is no temporary dip caused by one bad year or a rough patch in the economy. It is the result of a retreat from family formation that has been underway for more than sixty years.

Fertility is more than another government statistic. It tells us whether a civilisation still believes in its own future. Perhaps it is the single best measure we have of that belief. It tells us whether people have the confidence, money, health, and stability to raise the next generation. When the number keeps falling, year after year, something has gone badly wrong. Usually, several things have.

The consequences will not arrive with sirens blaring. Demographic decline moves slowly enough for politicians to ignore it, only to become so entrenched that it can be reversed only at enormous social and economic cost, if it can even be reversed at all.

Fewer workers will have to support more retirees. A smaller tax base will be asked to pay for hospitals, pensions, aged care, and a swollen public service. Schools will close as suburbs and towns age. Regional communities will lose young families. Defence forces will chase a shrinking pool of recruits. Economic growth will become increasingly dependent on importing people rather than building a country in which Australians can afford to have children.

Japan and South Korea provide a warning of where this can lead. South Korea’s fertility rate fell to 1.4 in 1999 and eventually sank to 0.7. Japan has continued falling towards 1.1 despite decades of concern, government programs, and increasingly desperate attempts to convince people to marry and reproduce.

Singapore and China have also discovered that once very low fertility becomes normal, generous incentives do not easily reverse it. And when children become unusual, the culture, economy, and institutions begin adapting to their absence.

People grow up with fewer siblings, cousins, nieces, and nephews. Workplaces become less accommodating to parents because fewer employees are parents. Housing is designed for singles and couples. Social life revolves around adults without children, and having a family begins to feel like an eccentric undertaking rather than the ordinary course of life. Low fertility can become self-reinforcing. A society with fewer children becomes a society less organised around children, which makes raising them even harder.

The federal government expects natural population growth, births minus deaths, eventually to turn negative. Immigration can delay that day, but it cannot cancel it. Australia’s age structure is already being reshaped by lower fertility, longer life expectancy, and the sheer scale of migration.

Still, Canberra has a familiar answer. Raise the migration target and declare the quarterly numbers healthy. That has become the standard response whenever the country’s underlying weaknesses show through. Productivity stalls, so import more people. The population ages, so import more people. Young Australians cannot afford children, so they import people whose children were born somewhere else.

Migration can increase the population, but it cannot provide a permanent escape from an ageing society, particularly when migrant fertility tends to drift towards the norms and costs of the country migrants settle in. The children of migrants face the same house prices, childcare fees, taxes, relationship instability, and career pressures as everyone else. Over time, their family size usually begins to resemble that of the wider population. (However, Muslim migrants do tend to have a much higher birth rate than any host Western country they settle in, leading to massive demographic changes in the long run, but that, while linked to fertility, is another story.

Australia has become very good at hiding its demographic failure without fixing it.

The usual explanations for falling fertility are real enough. Housing is expensive, jobs feel less secure, marriage happens later, childcare costs a fortune, and raising children has become a major financial undertaking.

The Commonwealth’s Centre for Population found that living costs for employee households rose by 55 percent between 2007 and 2024. Australian house values rose by about 150 percent between 2011 and 2024. Home ownership is still seen by many Australians as something that should come before children. Nobody who has watched a young couple calculate a deposit, childcare fees, and mortgage repayments would find that surprising. The only people who seem genuinely puzzled are the ones making housing policy.

The geography tells much the same story. Fertility has been especially weak in expensive capitals such as Melbourne and Sydney, while relatively more affordable regions have often recorded higher rates. That does not prove house prices are the sole cause, but it is a fair clue. A couple looking at a two-bedroom unit in inner Melbourne may be able to imagine one child. A family-sized home within commuting distance is another matter. By the time they have scraped together the deposit, survived several rent rises, and found somewhere with enough bedrooms, years have passed.

A generation has been told to get a degree, build a career, save a deposit, buy a wildly overpriced home, achieve financial security, and then think about children. By the time many people work their way through that list, they are already in their thirties and discovering that biology never agreed to the timetable.

Biology does not negotiate with ideology, career planning, or the property market. The official data makes the point plainly. Australian mothers now have a median age above 32. Delaying the first child does not simply move the same family a few years down the road. It leaves less time for a second, third, or fourth child and raises the chance that age-related fertility problems will intervene.

Government analysis has found that women with post-secondary qualifications had their first child about 3.5 years later than women without those qualifications during the period studied. They also had around 0.14 fewer children on average. That does not mean education is bad or that women should be herded out of universities. It shows that the sequence we have built has consequences. Longer education delays full-time work, a stable income, homeownership, partnering, and, eventually, children. This is an argument against pretending that family formation can be postponed forever without cost.

Modern corporate feminism sold women a rather convenient version of liberation. Women were told that fulfilment meant becoming economically interchangeable with men. The corner office, the professional title, and the uninterrupted CV were celebrated. Motherhood was often treated as a disruption to the important business of paid work. The economy soon adjusted. Two full-time incomes became normal, house prices swallowed the extra earning power, governments collected more tax, and families found that what one wage once provided now required two. Some liberation.

Women are expected to work as if they have no children and raise children as if they have no job. Men are told that traditional responsibility is backward or oppressive, then blamed when they fail to provide stability. Both sexes are taught to treat independence as the highest good, until independence begins to look a lot like loneliness. We built a two-income economy without fully adjusting family life to match. Women gained jobs but often kept most of the old domestic load. Men lost the clear social expectation that they should provide, protect, and lead a family, but were not always given a compelling replacement role. The result has not been equality so much as exhaustion and confusion.

The retreat from marriage matters as well. Children are easier to plan and raise in a stable partnership, yet commitment has been weakened by prolonged adolescence, casual relationships, and an online dating culture that offers endless choice but not much trust. People marry later. Relationships end more readily. More Australians remain single throughout their prime reproductive years. Some choose that life. Others find themselves there after years of short relationships, failed dating apps, and partners who were never quite ready to commit.

Government demographic research identifies delayed partnering, cohabitation, relationship breakdown, and lifelong singleness as part of the fertility story.  Divorce also plays a part. Couples are less likely to have several children when they are not sure the relationship will survive the mortgage.

Culture shapes desire, too. The modern person is trained to chase travel, consumption, convenience, freedom, and self-expression. Children ask for something else entirely. They require sacrifice, patience, routine, compromise, and the acceptance that somebody else’s needs may come before your own. We have built a society optimised for consumption, not family.

Young people are repeatedly told what children will cost them: sleep, money, travel, career progress, freedom, and an attractive body. We then act surprised when they hesitate. At the same time, parenting has become a competitive sport. Parents are expected to provide a large home, the right school, organised sport, constant supervision, endless emotional reassurance, and a childhood fit for social media. Raising an ordinary, resilient child no longer seems to be enough. We have made children less appealing and parenthood more demanding.

There are signs that Australians are not only failing to have the families they want. Some now want smaller families in the first place. Analysis of HILDA survey data found that among women aged 25 to 29, the average desired number of children fell from 2.52 in 2005 to 2.13 in 2023. Among men of the same age, it fell from 2.28 to 1.86. That is a serious cultural shift. A desired family size below two among men aged 25 to 29 suggests that the retreat is happening before infertility treatment, mortgage stress, or the late-thirties biological clock enters the picture.

Younger women aged 18 to 29 also reported wanting fewer children in 2023 than women of the same age did in 2005. The 2025 Population Statement says fertility intentions have been falling since 2001, although the number of children people say they want is still higher than the number they actually have. That gap matters. Some Australians genuinely prefer one child or none. Others still want two or three but cannot afford the house, cannot find a partner, cannot risk stepping away from work, or discover too late that conception is harder than expected.

More men are deciding, earlier and permanently, to limit reproduction. Adelaide University researchers reported that vasectomies among Australian men aged 18 to 44 rose by more than 60 percent, from 18,544 procedures in 2016 to 29,848 in 2024. The rise occurred in every state and territory and included younger men.

The decision to remain childless is also becoming more culturally normal. In some circles, children are spoken about almost as an environmental offence or an irresponsible financial gamble. Adults compare overseas trips, restaurants, and investment portfolios, while parenthood is treated as the road not taken by people who failed to plan properly.

Even pets have been drawn into the change. Australians increasingly hold birthday parties for dogs, push them in prams, buy designer clothing for them, and refer to themselves as pet parents. There is nothing wrong with loving an animal. Most families do. It becomes culturally revealing when pets begin filling the emotional and social space once occupied by children. Nurturing instincts do not vanish. They are redirected towards something cheaper, less permanent, and far less demanding than raising another human being.
