About this ranking

People born outside the country where they live, as a percentage of the total population. United States: people who were not US citizens at birth, including naturalized citizens, lawful permanent residents, temporary migrants and unauthorized immigrants; American Community Survey five-year estimate, where the period shown is the last year of the five-year span. EU countries: residents on 1 January whose country of birth is not the reporting country (Eurostat). England and Wales: usual residents born outside the United Kingdom, Census 2021.

Based on place of birth, not nationality: a naturalized citizen counts as foreign born. In the United States people born in Puerto Rico, the US island areas or abroad to American parents count as native; in the EU everyone born outside the reporting country counts as foreign born, including people born in another EU country or abroad to national parents. Not comparable with foreign_population_share, which counts foreign nationals in Spain and the EU.

Every value in the ranking comes from the same publisher and the same period, so the cities are compared on one definition. Equal values share a rank.
