Estimates are presented for 1990, 1995, 2000, 2005, 2010, 2015, and 2020 and are available for 232 countries and areas of the world. The estimates are based on official statistics on the foreign-born or foreign population.
The estimates of the number (or “stock”) of international migrants disaggregated by age, sex and country or area of origin are based on national statistics, in most cases obtained from population censuses. Additionally, population registers and nationally representative surveys provided information on the number and composition of international migrants.
