About this data

• The UN's estimates are produced every five years (plus 2024), using censuses and population surveys.
• ONS's own estimates, based on the 2021 Census and migration data, are a little higher: 18.9% of the UK population was born abroad in mid-2024. See the chart of the non-UK-born population.
