In this Q&A and video, learn about the methods and data sources the Center used to estimate the number of unauthorized immigrants in Europe.
The size of Europe’s unauthorized immigrant population in 2017 was less than half the number in the United States.
The number of unauthorized immigrants living in Europe increased between 2014 and 2016, then leveled off to an estimated 3.9 million to 4.8 million in 2017, according to new estimates from Pew Research Center.
Most live in Germany, the UK, Italy and France, and about half had arrived in Europe in recent years. Overall, these migrants account for less than 1% of Europe’s total population.
Every year, we publish hundreds of reports, blog posts, digital essays and other studies. Here are some of our most noteworthy findings from the past year.
