Abstract:Place of birth and nationality are the two criteria most commonly used by OECD countries to define their immigrant population. Based on the first criterion, migrants are persons residing in a country but born in another, i.e. first‐generation migrants. According to the second criterion, migrants are residents who have the nationality of their home country, and may include persons born in the host country. Cross‐country differences between the size of the foreign‐born population and that of the foreign population depend on the rules governing the acquisition of citizenship in each country. In general, estimates of the foreign‐born population are substantially higher than those based on nationality. While different national definitions have traditionally limited cross‐country comparability of the stock of migrants in different OECD countries, this issue of Society at a Glance presents for the first time comparable data of the foreign‐born population derived from population censuses (Dumont and Lemaître, 2005).
