A new report from the Berlin Institute for Population and Development, conducted in partnership with the Wüstenrot Foundation, forecasts that Germany’s population will drop from 83.5 million in 2025 to approximately 81.8 million by 2045. However, experts emphasize that the primary challenge is not merely the overall decline, but the rapid aging of society and a shrinking labor force. The working-age population is expected to decrease by 4.7% nationally over this period.
Catherina Hinz, president of the Berlin Institute, highlighted the generational imbalance driving these trends. “The baby boomer generation is retiring, while significantly smaller cohorts are following. Birth rates are falling, and immigration is not sufficient to offset the growing surplus of deaths over births,” Hinz stated during the study’s presentation in Berlin. She noted that annual births exceeded one million during the 1960s baby boom, a figure that subsequently fell sharply, effectively halving.
According to the researchers, demographic shifts are not affecting all areas equally. Economic attractiveness and municipal financial health are becoming increasingly decisive factors in determining whether a region grows or contracts. Hinz warned that the divide between different parts of the country is widening, even within eastern and southern Germany as well as rural zones. “Demographic change is unfolding before our very eyes… Its consequences can still be mitigated, but they can no longer be avoided. And the longer we wait, the narrower our scope for action will become,” she said.
Frederick Sixtus of the Berlin Institute pointed out that nearly every region now records more deaths than births, a legacy of decades of low fertility. Consequently, migration has become the key variable shaping local demographics. While international immigration has historically stabilized population numbers, it is no longer sufficient to reverse societal aging on its own. To remain competitive, regions must offer high-quality employment, adequate skilled labor, financially stable municipalities, reliable childcare, and efficient transportation networks.
Manuel Slupina of the Wüstenrot Foundation indicated that major metropolitan areas will continue to attract residents. Berlin is projected to lead this trend, with its population expected to rise by nearly 10% by 2045. Other gaining cities include Hamburg, Frankfurt am Main, Munich, and Düsseldorf in the west, alongside Leipzig, Dresden, and Potsdam in the east. Interestingly, the study challenges the traditional urban-rural divide, noting that hinterlands near large cities may also grow as families with children move away from dense metropolitan centers.
Conversely, several large western German cities, including Bremen, Duisburg, Dortmund, and Kaiserslautern, are expected to lose population due to diminishing economic appeal. The most vulnerable areas are sparsely populated regions, particularly in eastern Germany. Twelve of the twenty districts and independent cities with the lowest overall ratings are now in the east, up from just five in 2019. These areas could see their working-age populations plummet by as much as 18% by 2045.
The competition for talent is expected to intensify, with Bavaria and Baden-Württemberg identified as having the strongest prospects. Bavaria, in particular, benefits from a robust economy and strong labor market, showing higher employment rates among women, older adults, and non-citizens compared to other regions. This suggests that economically successful areas are better equipped to integrate diverse population groups into the workforce.
The study urges policymakers to adopt tailored solutions rather than one-size-fits-all approaches. Slupina argued that growing cities and shrinking rural districts require different strategies, necessitating less rigid regulation and greater financial autonomy for local authorities. While municipalities are currently advocating for a larger share of tax revenues, federal and state governments cite their own budgetary constraints. Nevertheless, both sides acknowledge that reforming fiscal federalism is an inevitable requirement for addressing these long-term demographic challenges.
Finally, a report admitting one size fits none. Local solutions matter more than federal broad strokes.
