Staff Writer Kaya Newhagen examines the origins and polemic politics of pronatalism and what’s actually driving our demographic downturn.
For decades, policymakers feared overpopulation. Now, across the developed world—and increasingly beyond it—birth rates are falling below the replacement rate of 2.1 children per woman. Since 1950, the global fertility rate has dropped from roughly five births per woman to 2.3 today. Only about a third of countries remain above replacement level—much of sub-Saharan Africa and parts of Central Asia continue to post high rates—but the decline is spreading rapidly.
The United Nations projects that the global population will peak around 2080. Yet even that estimate rests on the assumption that falling fertility will stabilise. Some argue that if rates do not rebound, the peak could arrive decades earlier. The world has not seen sustained global population decline since the mid-14th century.
Falling birth rates are not solely a product of policy failure. They are a structural outcome of modern societies. Reactively treating them as a crisis to reverse has led governments into incoherent, expensive and politically contradictory policies
In the United States, pronatalism has increasingly been associated with the political right. Yet the alignment is not absolute. Not all conservatives are pronatalist, and not all pronatalists are conservative. In recent years, however, the movement has acquired an unmistakable political charge. During the 2024 presidential campaign, JD Vance amplified the debate when he criticised what he called a country run by “a bunch of childless cat ladies”. This sentiment has found organised expression. Events such as NatalCon have become gathering grounds for a loose coalition of conservatives, technology optimists and traditionalist influencers united by a shared fear of “demographic collapse”.
Yet the politics of pronatalism are not confined to rhetoric. Hungary offers the clearest example of a state-led pronatal strategy. Prime Minister Viktor Orbán has made reversing fertility decline a central political mission, framing it in explicitly cultural and national terms. His government has devoted a substantial share of GDP to family support: tax exemptions for mothers, subsidised housing loans and direct payments for large families. The results, however, have been limited. Hungary experienced a temporary increase in births, but the rise mostly reflected couples bringing forward planned children rather than increasing the total number they would have over a lifetime. The policy has proved costly and politically symbolic, but not transformative.
Scandinavia presents a different model. The region has long pursued policies designed to make child-rearing compatible with modern working life: heavily subsidised childcare, generous parental leave and flexible labour markets. Denmark’s “flexicurity” system, combining labour flexibility with social security, is often cited as an example of institutional adaptation. Yet even there fertility has continued to decline. Although governments have expanded support, including subsidised IVF treatments, sustained returns to replacement-level fertility have not materialised. The Nordic approach aims less at reversing demographic decline than at mitigating its social costs.
Common explanations for declining fertility are also misguided. A popular claim is that women’s expanding ambitions are to blame. As women become wealthier and more educated, the theory goes, they prioritise careers over children. The data complicates this narrative. Over the 20th century, fertility rates among rich and poor women converged. In the United States today, college-educated women and higher-income women now often have slightly more children than lower-income counterparts. Meanwhile, one of the largest contributors to the overall fertility decline has been the sharp fall in teenage pregnancy. This is widely regarded as a public policy success. For decades, governments invested heavily in reducing early and unintended births, particularly among young women. Now some of those same societies are alarmed that fertility is too low.
The fertility decline is better understood through structural forces: later marriage, urbanisation, rising opportunity costs of child-rearing and expanded female education. Children are no longer economic assets in agrarian households; they are emotional and financial commitments in urban economies. To fiscally sway fertility upward would require enormous investment, long-term redistribution, and would be difficult to politically justify in ageing societies already facing mounting pension and healthcare burdens.
If domestic births fall, immigration offers a partial offset. The United States has long benefited from higher fertility among first-generation immigrants. Singapore has used its international appeal to attract foreign workers. Some European economies rely increasingly on migrant labour. Yet immigration is not a permanent solution. First, political resistance to immigration has intensified across many Western countries. Second, the fertility advantage of immigrants typically fades by the second or third generation. Third, the fertility decline is no longer confined to rich countries. Immigration can mitigate demographic pressure, but not relieve it.
An aging population carries clear fiscal implications. Fewer workers must support more retirees. Pension systems strain. Healthcare costs rise. Debt burdens increase. There are potential offsets. Older populations may save more and consume less, keeping interest rates lower. Labour shortages could accelerate automation and productivity gains. People are also working longer and remaining healthier for more years than previous generations. But the demographic transition creates awkward lags. Even if pronatal policies worked tomorrow, newborns would not enter the workforce for two decades. In the interim, societies face an expanding elderly population and a relatively thinner middle generation to support it.
Some optimists point to medical advances. Fertility treatments such as IVF, egg freezing and emerging reproductive technologies may extend the biological window for childbirth. If women can have children later in life without greater health risks, total fertility could stabilise. Others argue that productivity gains, artificial intelligence and automation may offset labour shortages. If fewer workers are needed to produce the same output, a smaller workforce need not mean economic decline. These developments may ease some pressure. But they do not change the underlying fact that fertility decline reflects structural preferences in modern societies. The opportunity costs of raising children—in time, income and flexibility—remain high.
Some, including Elon Musk, frame falling fertility as the greatest threat to civilization. Others welcome slower population growth as environmentally beneficial, arguing that fewer people will ease strain on climate and resources. Both views are likely oversimplified. Birth rates fell because societies modernised. Women gained education. Child mortality fell. Urban economies replaced agrarian ones. These shifts reflect progress, not decay. The real danger is not that people are choosing to have fewer children, it is that governments refuse to adjust to the consequences of that choice.
