Migration[edit]

According to the 2012 French census, 586,163 residents of the City of Paris, or 26.2 percent, and 2,782,834 residents of the Paris Region (Île-de-France), or 23.4 percent, were born outside of Metropolitan France (the last figure up from 22.4% at the 2007 census).^[137]
26,700 of these in the City of Paris and 210,159 in the Paris Region were people born in Overseas France (more than two-thirds of whom in the French West Indies) and are therefore not counted as immigrants since there are legally French citizens at birth.^[137]
A further 103,648 in the City of Paris and in 412,114 in the Paris Region were born in foreign countries with French citizenship at birth.^[137] This concerns in particular the many Christians and Jews from North Africa who moved to France and Paris after the times of independence and are not counted as immigrants due to their being born French citizens.
The remaining group, people born in foreign countries with no French citizenship at birth, are those defined as immigrants under French law. According to the 2012 census, 135,853 residents of the city of Paris were immigrants from Europe, 112,369 were immigrants from the Maghreb, 70,852 from sub-Saharan Africa and Egypt, 5,059 from Turkey, 91,297 from Asia (outside Turkey), 38,858 from the Americas, and 1,365 from the South Pacific.^[144] Note that the immigrants from the Americas and the South Pacific in Paris are vastly outnumbered by migrants from French overseas regions and territories located in these regions of the world.^[137]
In the Paris Region, 590,504 residents were immigrants from Europe, 627,078 were immigrants from the Maghreb, 435,339 from sub-Saharan Africa and Egypt, 69,338 from Turkey, 322,330 from Asia (outside Turkey), 113,363 from the Americas, and 2,261 from the South Pacific.^[145] These last two groups of immigrants are again vastly outnumbered by migrants from French overseas regions and territories located in the Americas and the South Pacific.^[137]
In 2012, there were 8,810 British citizens and 10,019 US citizens living in the City of Paris (Ville de Paris), and 20,466 British citizens and 16,408 US citizens living in the entire Paris Region (Île-de-France).^[146][147]
