Select the type of statistics:


For each country, insofar as these are available, you can find aggregate data from 1985 onwards on the following characteristics of acquisitions of citizenship: total number of acquisitions, mode of acquisition (procedure), citizenship of origin, country of birth, region of residence, sex, age, decisions on applications for naturalisation. These data are summarised in charts on each country statistics page and can be downloaded in spreadsheet format for further analysis. At the top of the statistics page of each country users can find a document indicating which type of data are available for that country, for which years, and also from which sources those data were gathered. Users can also export comparative tables, with a selection of countries, years, and acquisition characteristics.
