International migrant stock, total

The measure of individuals residing in a country different from their birthplace, this indicator encompasses a diverse population, including refugees and those seeking better opportunities abroad. The estimation process primarily relies on national population censuses, which provide insights into the foreign-born populace. In cases where direct data is lacking, statistics on foreign citizens residing within a country are utilized. The dissolution of the Soviet Union in 1991 significantly transformed migration patterns, as individuals from newly independent states were reassessed as international migrants based on historical census data. Additionally, for nations with limited temporal data on migrant demographics, statistical techniques such as interpolation and extrapolation are applied, allowing for a comprehensive understanding of migration trends over time.
