Total (thousands): The estimated total number of international migrants, both sexes combined, as of 1 July of the years indicated, in thousands. The basic data used to estimate the number of international migrants was obtained mostly from population censuses. For 179 countries or areas, the estimate shown corresponds to the number of persons born in a country other than that in which they lived, that is, the foreign-born population. For a further 42 countries or areas where information on place of birth was not available, the estimate shown corresponds to the number of foreigners. For the remaining 9 countries or areas, no information on the number of foreign-born or foreign persons was available; the estimates were imputed using a model.
