Out of the 59.6 million usual residents in England and Wales in 2021, 49.6 million (83.2%) were born in the UK and 10.0 million (16.8%) were born outside the UK. This means that about one in six people in England and Wales were born outside the UK. The size of the non-UK born population has risen since 2011, when it was 7.5 million (13.4%).

Those born in the European Union (EU) made up 3.6 million (36.4% of all non-UK born usual residents) of the population, an increase from 2.5 million (32.7%) in 2011 (including Croatia, who joined the EU in 2013). The remaining 6.4 million (63.6%) were born outside the EU, up from 5.1 million (67.3%) in 2011.
