The foreign-born population of the European Union exceeded 64 million, or 14 percent of the population, in 2025—a historic high. Spain alone accounted for roughly one-third of the bloc’s annual increase, according to a new report from the Center for Research and Analysis of Migration at RFBerlin, an independent research institute.
The study, titled “The Immigrant Population in the European Union: Growth, Concentration and Dispersion” and authored by economists Tommaso Frattini and Camilla Piovesan, draws on Eurostat and U.N. Refugee Agency data to map the sharp and uneven growth in migration flows across the 27-member bloc.
