Sweden’s sharply declining birth rate is no longer a distant demographic concern. It is becoming a near-term economic and fiscal problem with direct consequences for growth, public finances, and the sustainability of the welfare state.
That is the conclusion of the first interim report from the government-appointed population inquiry, presented this week. The report focuses not on why Swedes are having fewer children or how policy might reverse the trend, but on what different fertility scenarios would mean for the economy and public sector over time.
The numbers are stark. In 2023, Sweden’s total fertility rate fell to 1.4 children per woman, the lowest level recorded since measurements began in the 18th century. For a stable population, the rate needs to be around 2.1.
“This is not a future scenario. It is happening here and now,” said Minister of Social Affairs Jakob Forssmed (Christian Democrats) at the presentation.
From demographic shift to economic shock
The inquiry models several fertility trajectories. In the most pessimistic scenario, Sweden’s population could shrink by around four million people by the end of the century, according to lead investigator Åsa Hansson, associate professor of economics.
The economic implications are severe. In such a scenario, more than half of today’s GDP could disappear over time as the workforce contracts and consumption declines.
This is not simply a question of fewer workers supporting more retirees. A shrinking population affects the entire economic ecosystem: labour supply, tax bases, housing demand, capital formation, and productivity dynamics. Fewer children today translate into fewer employees, entrepreneurs, and taxpayers tomorrow.
Hansson notes that both fiscal and monetary policy would be forced to adapt to a structurally weaker growth environment. Lower potential growth makes it harder to finance pensions, healthcare, education, and defence without higher taxes or reduced services.
Early warning signs already visible
Some of the effects are already emerging. As cohorts shrink, municipalities are closing preschools and childcare facilities. That may look like a short-term cost saving, but it creates longer-term challenges for local labour markets, particularly for parents whose ability to work depends on childcare availability.
“This will have a domino effect throughout society,” Hansson said.
For the public sector, the challenge is asymmetric. Costs related to aging rise steadily, while revenues linked to working-age populations weaken. That imbalance puts sustained pressure on municipal finances and raises questions about the current welfare model’s design.
No easy fixes, no external escape
Declining fertility is not unique to Sweden. Most advanced economies, including across the EU, face similar trends. But the government has been clear that the inquiry is focused on national solutions rather than cross-border arrangements.
“There is a strong desire to find a recipe for Sweden,” Forssmed said.
While labour migration can ease short-term shortages, it does not solve the underlying demographic arithmetic unless migrants themselves have higher birth rates over time. Nor can automation fully compensate for a shrinking consumer base.
What the government is doing now
Asked about immediate measures, Forssmed pointed to improved household finances for families with children from the start of the year and increased construction of single-family homes.
These steps may help at the margin, particularly by addressing cost-of-living pressures and housing constraints that delay family formation. But the inquiry makes clear that reversing fertility decline, if it is possible at all, would require sustained, broad-based policy changes over decades rather than isolated reforms.
The interim report reframes low fertility from a social issue into a macroeconomic risk. For businesses, investors, and policymakers, the message is clear: demographics are becoming a binding constraint on Sweden’s long-term growth model.
The inquiry’s mandate has now been extended until 2028. By then, the challenge will be even harder to ignore. The real question is not whether Sweden can afford to act, but whether it can afford not to.
