Grants of citizenship awarded by the reporting country to persons who were previously citizens of another country or stateless.
Losses of the citizenship of the reporting country.
The disseminated series comprise: Total number of acquisitions of citizenship and since 2008 the number of losses of citizenship.
The data sources are administrative records in the reporting countries. The completeness of the tables depends largely on the availability of data from the relevant national statistical institutes and other responsible bodies in the countries. However, not all countries are always able to provide data.
Countries differ in terms of the conditions that must be fulfilled to acquire citizenship or to lose the citizenship. Generally, to acquire citizenship a period of (legally registered) residence is required, combined with other factors such as evidence of social and economic integration and knowledge of national languages. Different conditions may apply for persons who were born or educated in the country concerned, or who have parents or other relatives with that country's citizenship.
