Citizenship Statistics

EUDO Citizenship collects statistics on the acquisition of citizenship, as well as on the loss of citizenship. You can find these statistics in two databases on citizenship statistics:

Database on Statistics on Acquisition of Citizenship

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. 

Database on Statistics on Loss of Citizenship 

For 28 EU Member States, insofar as these are available, you can find aggregate data from 1985 onwards on the total numbers of loss of citizenship in a country, as well as on mode of loss of citizenship. 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 procedural characteristics.

 

Sources

The data presented here are derived from publicly accessible national sources European countries. These sources are typically national statistics agencies, but also Ministries of Justice or Home Affairs, Immigration and Naturalization Services, or Immigration Boards. EUDO CITIZENSHIP country experts provided important input for the data presented here.

 

Disclaimer

We aim to present data in a uniform format allowing for comparison across countries, but such comparisons always need to be done with careful consideration of national legislation and information on how the data have been collected. Please note that the source documents also include notes on country-specific aspects of the data.

For an earlier analysis of citizenship statistics in the EU-15 you can download here a 2006 book chapter by Harald Waldrauch based on data collected in the NATAC project.

The PROMINSTAT project provides a useful inventory of available statistics on migration and integration of immigrants, which includes also naturalisation statistics. 

EUROSTAT collects data on acquisition of citizenship in all EU member states, EFTA and EU candidate countries, and provides a breakdown by age, sex and previous citizenship. 

You can access here the EUROSTAT online database on acquisition of citizenship and the database on loss of citizenship, the citizenship section in Eurostat’s "Statistics Explained", as well as a short analytical publication on citizenship statistics.
