Luxembourg: A single line in the latest Eurostat projections captures the decade ahead, and it explains why a shrinking workforce now shadows almost every fiscal debate in the Union. According to Demography of Europe 2026, the EU population will crest at roughly 453.3 million people around this year before beginning a long, gradual decline toward 419.5 million by 2100.
The headline number matters less than its composition. The people the Union is losing are disproportionately of working age, while the fastest-growing group is the oldest. That combination reshapes public finances more powerfully than any single policy choice a government could make.
The numbers behind the strain
Eurostat expects the working-age population, those aged 15 to 64, to fall by about 13 percent between 2022 and 2060, with the Union shedding roughly a million workers a year until 2050. At the other end of life, people aged 65 and over will make up 32.5 percent of the population by 2100, up from 22.0 percent in 2025.
The dependency ratios tell the story in one figure. The old-age dependency ratio, which weighs older people against those of working age, is projected to nearly double from 34.5 percent in 2025 to 59.7 percent by 2100. Fewer workers will support more retirees, and the arithmetic tightens with each passing year.
The pressure falls unevenly. By 2050, working-age populations are set to decline in 22 of the 27 member states, and the share of people aged 85 and over across the Union will more than double. A demographic divide is opening between regions that attract younger migrants and workers and those that steadily empty out.
What it means for policy
These projections are not neutral background. They quietly set the ceiling on growth, because an economy with fewer workers must squeeze more output from each of them or accept a slower pace. They also strain pensions, healthcare, and long-term care budgets precisely when the tax base that funds them narrows.
Policymakers have three broad responses, and none is painless. They can raise labour participation, drawing in more women, older workers, and the currently inactive. They can lift productivity through investment and technology so that fewer hands produce more. Or they can turn to migration, which several analysts frame as the most immediate lever, though it carries political costs that governments weigh carefully.
Enlargement enters the conversation here too. Some argue that admitting younger populations from candidate countries could soften the Union’s ageing, yet those same countries face steep demographic declines of their own, so the relief may prove smaller and more temporary than hopeful sketches suggest.
There is a risk in treating demography as destiny. Participation rates can rise faster than models assume, automation can lift output per worker, and healthier ageing can keep people economically active for longer. The projections describe a trajectory under current behaviour, not an immovable fate.
Still, the direction is clear enough to demand attention now rather than later. A shrinking workforce does not announce itself with a crisis on a single morning; it arrives slowly, budget by budget, until the choices left are narrow and expensive. The value of the Eurostat data is that it gives governments the years of warning they need, if they choose to use them.
