International migrant stock by destination with analytics by countries of origin | Italy – yearly data, chart and table

International migrant stock is the number of people born in a country other than that in which they live. It also includes refugees. The data used to estimate the international migrant stock at a particular time are obtained mainly from population censuses. The estimates are derived from the data on foreign-born population--people who have residence in one country but were born in another country. When data on the foreign-born population are not available, data on foreign population--that is, people who are citizens of a country other than the country in which they reside--are used as estimates. After the breakup of the Soviet Union in 1991 people living in one of the newly independent countries who were born in another were classified as international migrants. Estimates of migrant stock in the newly independent states from 1990 on are based on the 1989 census of the Soviet Union. For countries with information on the international migrant stock for at least two points in time, interpolation or extrapolation was used to estimate the international migrant stock on July 1 of the reference years. For countries with only one observation, estimates for the reference years were derived using rates of change in the migrant stock in the years preceding or following the single observation available. A model was used to estimate migrants for countries that had no data. In producing the 2024 edition of the International Migrant Stock dataset, the Population Division has prioritized revising the estimates for countries with new empirical information from population censuses or registers and relatively large numbers of international migrants, as well as for countries affected by ongoing or emergent refugee flows as documented by UNHCR. In the new edition of these data, a total of 60 countries and areas received a full reassessment of trends in the number of international migrants residing in the territory. For the remaining countries and areas, the estimates generated in 2024 reflect extrapolations of estimates published in the 2020 edition of the dataset.
