New report: The public finance implications of fewer children and an ageing population
In our latest report from the Committee for a Future with Children we challenge the conventional assumptions about how demographic change affects public finances. While public debate often focuses on the fiscal pressures created by population ageing, the report shows that declining birth rates have important and often overlooked effects that can temporarily strengthen public finances before generating more significant challenges later on.

The analysis examines how different demographic scenarios affect Sweden’s public finances over both the short and long term. A central finding is that lower birth rates initially reduce public expenditure on childcare, education and other services aimed at children and young people. These savings can outweigh the costs associated with an ageing population for many decades, resulting in stronger fiscal balances than commonly expected. The report finds that, depending on future fertility and migration trends, the public finances may not deteriorate substantially until well into the second half of the century.
However, the report stresses that stronger public finances should not automatically be interpreted as a sign of economic strength. As population growth slows, economic activity in the household and business sectors declines as population growth wanes, which dampens aggregate demand and income growth in the entire economy. Employment, consumption and investment all come under pressure – particularly when low fertility coincides with declining migration. As a result, public finances and the wider economy may move in opposite directions.
That divergence may help explain the persistent economic sluggishness observed in many European countries today. Eventually, however, the arithmetic catches up with the public finances as well. As smaller generations enter the labour market, workforce growth slows or reverses. Tax revenue become harder to sustain, while the share of retirees in the population continues to rise. Dependency ratios climb, growth weakens and fiscal pressure mounts. A weaker economy only amplifies those pressures on public finances in the long term.
The report’s conclusion is that the composition of the population matters at least as much as its size. Societies with a larger share of children and young adults ultimately achieve stronger economic growth, lower dependency ratios and more sustainable public finances. Policymakers should therefore view children and young people not primarily as a public expenditure, but as an investment in future labour supply, human capital and long-term prosperity. The report argues that today’s fiscal gains from lower birth rates should be used strategically to improve the conditions for family formation, strengthen labour-force participation and support sustainable economic development in the decades ahead.
