According to the latest forecast by the Senate Chancellery, Berlin is expected to have around 4.006 million inhabitants by the year 2040—an increase of about 109,000 people, or 2.8%, compared to the previous year. However, this growth is unevenly distributed: eight districts are expected to grow, while four districts are projected to experience a population decline.
Treptow-Köpenick is forecast to see the strongest relative increase at around 9.6%, followed by Lichtenberg with 8%. In absolute terms, Treptow-Köpenick and Pankow lead with an expected gain of approximately 28,000 residents each, closely followed by Lichtenberg with around 25,000.
Berlin’s population forecast is regularly compiled by the Senate Department for Urban Development, Building and Housing. It outlines how the city’s total population and demographic structure are likely to develop in the coming years—both citywide and for each individual district. The data serve as a basis for planning in areas such as schools and childcare, residential construction, transport infrastructure, and energy and water supply.
According to the forecast, the largest population declines are expected in Steglitz-Zehlendorf (–2.9%, or about 9,000 fewer residents) and Charlottenburg-Wilmersdorf (–2.5%, or roughly 8,400 fewer). As of the end of December 2024, the Berlin-Brandenburg Office of Statistics recorded 3,897,145 people with their primary residence in Berlin—an increase of around 19,045 people, or 0.5%, compared to the previous year.
