The Global Database on Modes of Acquisition of Citizenship includes information on the different ways in which citizenship can be acquired across the world. The database is organized around a comprehensive typology of modes of acquisition of citizenship, which outlines, in a systematic way, 27 ways in which citizenship can be acquired. For each ‘mode of acquisition’ the typology outlines a standardized ‘target person’ which allows comparing rules applicable to similar groups across countries.
The Global Database on Modes of Acquisition of Citizenship covers information on laws in force in 175 states on 1 January 2016 and, for countries in Europe and the Americas, also for the period 2013-2015. The Database will be updated annually.
The database allows two types of searches:
- List all modes of acquisition in one country: select ‘all modes’ and select the country you are interested in (for all available years or select a specific year).
- Compare a mode of acquisition across countries: select the mode of acquisition you are interested in and compare across all or selected countries (for all available years or select a specific year).
