evidence: These patterns are reflected in the distribution of the foreign-born resident population across the UK, for which the data are more up to date. Although London made up only 14% of the total UK population in 2020, it was home to 35% (3.3 million) of the UK’s foreign-born population (Figure 2). This represented more than 2.5 times as many foreign-born residents as in the South East, a region with about the same total population as London. Migrants born in non-EU countries were particularly likely to live in London – amounting to 2.3 million people, or 39% of all non-EU born migrants living in the UK in 2020. Although Northern Ireland has the smallest total and foreign-born populations in the UK, it has a larger EU-born population than the North East. This includes people born in the Republic of Ireland, which the ONS estimates comprised about 40% (36,000) of Northern Ireland’s EU-born population in 2020 (ONS, 2020).
