Berlin Nears Historic 4 Million Population Mark by End of 2025

Berlin's population is rapidly approaching the milestone of 4 million residents, with the city recording 3,913,644 inhabitants as of December 31, 2025, according to the Berlin-Brandenburg Statistical Office. This represents an increase of 16,500 people over the previous year. The population growth is uneven across the city, with ten of the twelve districts experiencing population increases. Treptow-Köpenick observed the most significant growth, adding 5,450 residents, a 1.8% rise. In contrast, Reinickendorf and Steglitz-Zehlendorf saw population declines of 0.9% and 0.2%, respectively.

The eastern part of Berlin is growing considerably faster than the western part, with an overall increase of 0.9% compared to just 0.1% in western districts. Despite a sharp drop in foreign immigration—from about 25,500 new registrations in 2024 down to 4,541 in 2025—the share of foreign residents remains stable at 24.9%. Notably, the TXL district experienced a dramatic population decrease of 52.2%, with foreign residents dropping by 66.4%. Blankenfelde in Pankow also reported a steep decline, with a 78.8% reduction in foreign residents. On the other hand, some areas like the landscape park in Adlershof and Oberspree in Treptow-Köpenick saw increases of 27.2% and 9.4%, respectively.

As Berlin inches closer to the symbolic 4 million mark, these demographic shifts highlight the city's evolving urban landscape and the disparities within its districts.
