How will a shrinking population strain Germany's pension system?
Core argument: Germany's population is projected to fall by more than 4mn to about 79mn by 2050, the lowest level since the early 1990s, with growth projected to hover around 0.4% in the long term.
Germany’s growth rate, projected to hover around just 0.4% in the long term, is likely to face further strain as the labour market comes under pressure from demographic decline. The number of people aged 20 to 66 is projected to fall by about 12%, while the number of pensioners is set to rise by more than 20%, Ifo said. Germany’s pay-as-you-go pension system is likely to come under increasing strain. The government already devotes about a quarter of its budget to supporting it, and the Federal Audit Office warned in 2024 that this share would rise further. By 2050, Germany’s population will fall by more than 4mn to about 79mn, the lowest level since the early 1990s. The inflow of migrants by 2030 is now expected to be significantly lower than previously forecast after the government tightened migration policy. Birth rates, too, were overestimated in earlier projections, with the new data pointing to 150,000 fewer births in 2030 than previously expected. According to Ifo, in 2025 Germany attracted only 225,000 net migrants compared with 454,000 in the previous estimate.
