Germany's Population Map Accelerates Its Split: East-West Gap Continues to Widen, Declining Regions Bear the Cost of Transition

According to a Deutsche Welle report, the latest population projection jointly released by the Berlin Institute for Population Research and Development and the Wüstenrot Foundation sketches an increasingly polarized picture: by 2045, Germany's total population will fall from 83.5 million in 2025 to roughly 81.8 million, with the overall working-age population shrinking by 4.7% over the same period. The institute stresses that the mere decline in aggregate figures is no longer the core challenge — what is more severe is the widening scissor gap between a continuously climbing number of retirees and a simultaneously shrinking labor force.

Presenting the study in Berlin, institute director Catherina Hinz stated bluntly: "The baby-boom generation is now retiring, while the cohort following it is significantly smaller. Birth rates continue to fall, and immigration is insufficient to close the gap in which deaths exceed births."

The report's core warning centers on regional inequality. Hinz said: "Some regions will lose large numbers of residents and workers in the coming years, while others will continue to grow. Even within eastern Germany, southern Germany, and rural areas, demographic and economic gaps are widening. Demographic change is unfolding before our eyes, its effects reaching across the country; the consequences, though still mitigable, can no longer be avoided — the longer action is delayed, the narrower the room to maneuver."

Growth poles are concentrated in a few urban regions. The report projects that Berlin will add nearly 10% to its population by 2045, placing it among Germany's fastest-growing cities. Western cities such as Hamburg, Frankfurt, Munich, and Düsseldorf, as well as Leipzig, Dresden, and Potsdam in the east, are likewise expected to sustain their growth momentum. The report also points out that the hinterlands of many large cities will continue to attract population — young workers flock to metropolitan areas, while families with children tend to settle in surrounding areas.

The shrinking map, by contrast, traces a markedly different trajectory. Formerly economically attractive western cities such as Bremen, Duisburg, Dortmund, and Kaiserslautern are projected to enter a population-loss track; the bottom of the ranking is occupied by sparsely populated areas, most of them in eastern Germany.

Changes in the geographic distribution of the lowest-rated districts reveal a continuing widening of the east-west divide: among the 20 districts and independent cities with the weakest overall ratings, the share located in the east has increased from 5 to 12. The working-age populations in these areas are forecast to experience the most precipitous contraction — falling by as much as 18% by 2045.

Frederick Sixtus of the Berlin institute notes that deaths now exceed births in nearly every region, the accumulated result of decades of low fertility. The direction of in- and out-migration now determines a region's demographic trajectory, but immigration alone is no longer sufficient to halt the aging of society. From this, the study draws the conclusion that competition for labor will become the central demographic challenge in the coming decades.

In this contest, Germany's southern states of Bavaria and Baden-Württemberg are judged to have the strongest outlook. Bavaria stands out in particular, thanks to a robust economy and an active labor market that reaches the whole state — with higher employment rates for women, older people, and non-German residents than elsewhere. The study notes that economically successful regions are more effective than weaker ones at integrating different groups into the labor market.

Manuel Slupina of the Wüstenrot Foundation emphasized: "What is the right response for a large city that is still growing is not necessarily suited to a rural area whose population is shrinking." He called for regulation to be made less rigid, for local authorities to be given greater autonomy, and for municipalities and grassroots actors to receive more adequate financial support. His message is clear: each region should be trusted to shape its own future.

Yet the appeals that local governments have made for years have yet to translate into substantive action at the federal level. Mayors and district administrators have long pressed for a larger share of tax revenues, while the federal government and the states have pushed back on the grounds of budgetary constraints. Although all sides recognize that Germany must sooner or later reform its fiscal federalism, the full weight of the delay continues to fall on ordinary residents in those regions already suffering continuous population loss and a weak economic base — pressed by structural imbalance to the limits of what they can bear.
