Comparing Citizenship Laws: Loss of Citizenship
EUDO CITIZENSHIP Global Database on Modes of Loss of Citizenship
The EUDO CITIZENSHIP Global Database on Modes of Loss of Citizenship includes information on the different ways in which citizenship can be lost across the world. Citizenship laws often use different terms for similar rules. Comparing legal provisions on acquisition and loss of citizenship requires therefore a standardisation of terms and definitions. The database is organized around a comprehensive typology of modes of loss of citizenship which outlines, in a systematic way, 15 ways in which citizenship can be lost. For each mode of loss of citizenship the typology outlines a standardized 'target person' which allows comparing rules applicable to similar groups across countries. See here for a complete overview of the comparative typology.
The Global Database incorporates the previous EUDO CITIZENSHIP Database on Modes of Loss of Citizenship in Europe, covering information on 41 European states, and will gradually expand its geographical scope. In a first phase, the Global Database adds information on 35 states in the Americas and the Caribbean. The Database includes information on laws in force in these 76 European and American states on 1 January 2015 (in a future expansion we also aim to provide information about citizenship laws in force in the past, but this feature is not yet incorporated).
The database allows two types of searches (search types cannot be combined):
- Country: search by country and view all regulations in one country.
- Mode: search by mode and view regulations across countries.
The EUDO CITIZENSHIP Global Database on Modes of Loss of Citizenship has been developed by a project team of EUDO CITIZENSHIP consortium members, coordinated by Maarten Vink and Olivier Vonk (Maastricht University) together with Rainer Baubock (European University Institute), Iseult Honohan (University College Dublin) and Gerard-René de Groot (Maastricht University). The Database relies on invaluable input from country experts who provide information on the interpretation and context of citizenship laws in Europe and the Americas.
The comparative typology of modes of loss of citizenship builds on earlier work by Harald Waldrauch (see more information here) and has been subsequently refined and expanded.

The 2015 update of the database on loss of citizenship has been supported the European Commission’s DG Justice, Citizenship and Fundamental Rights in the context of the ILEC project (Involuntary Loss of European Citizenship: Exchanging Knowledge and Identifying Guidelines for Europe), which aims to establish a framework for debate on international norms on involuntary loss of nationality.
