Declining birth rates for the fourth year in Germany
Last year marked the fourth consecutive year of decline in the birth rate and the lowest level since 1946.
Germany’s current replacement rate is at 1.35 children per woman, which is a record low and far below the 2.1 needed to maintain a stable population.
The Destatis attributes this trend to the entry of the relatively small birth cohorts born in the 1990s into the crucial fertile age of their early 30s, as well as the decline in the total fertility rate since 2022.
As in previous years, the number of births in 2025 fell more sharply in the eastern German states (-4.5%) than in the western states (-3.2%) compared to 2024.
Contrary to the trend, Hamburg was the only German state with an increase in birth rates, rising 0.5% in 2025.
Dastatis longterm projections, which extend to 2070, found that the population could shrink by around 10%. The report concludes that immigration will not offset the decline.
