Data source: United Nations, Department of Economic and Social Affairs (2015). Trends in International Migrant Stock: The 2015 revision (United Nations database, POP/DB/MIG/Stock/Rev.2015).
Almost 244 million people, or 3.3 percent of the world's population live in a country other than the one where they were born. This stock of migrants and refugess was much smaller in 1990 - only some 153 million.

In absolute terms it is not Northern America, which has the largest number of foreign born and refugees in their population, but Europe. In 2015, European countries reported some 76 million international migrants (foreign-born, foreign citicens and refugees); Northern America reported only some 54 million.

In Africa, there are currently (2015) some 21 million international migrants and in Latin America and the Caribbean there are only about 9 million.

Asia has a foreign born population including refugees of about 75 million - almost as much as Europe.

Note: The data used to produce the estimates refer to the foreign-born population or to foreign citizens. Whenever available, the number of refugees, as reported by UNHCR, were added to the estimate of international migrants. Estimates for countries or areas having no data on the number of international migrants were obtained by imputation.

In realtion to the population Northen America has more foreign-born people than Europe: about 15%, as compared to about 10%, are foreing-born.

Only a very small percentage of the population in Africa, Asia, and Latin America is foreing-born - between 1.5 and 1.7 percent of the population.
