T H E G L O B A L S TAT E O F C I T I Z E N S H I P Exploring the data The GLOBALCIT Citizenship Law Dataset, version v3 The data can be explored through two online databases on modes of acquisition of citizenship and modes of loss of citizenship. The databases provide information on the relevant article in the law for a provision, the procedure of acquisition or loss, as well as a summary description of the provision (‘Conditions’) and a standardised categorisation of the type of provision that allows comparing similar types of provisions across countries (‘Category’). What’s in the dataset? The GLOBALCIT Citizenship Law Dataset provides systematic information on the ways in which citizenship can be acquired and lost in 191 countries around the world. We define citizenship as a legal status and relation between an individual and a state or other territorial polity (such as the European Union, a federal province, or only partially recognised states) that entails specific legal rights and duties (see our online Glossary for more definitions of key terms you will encounter in this report). The Dataset is organised around a comprehensive typology of the many ways in which citizenship can be acquired and lost. This information facilitates comparisons of the rules applicable to similar groups across countries and provides a global outlook on the current state of citizenship law. These databases allow two types of searches: a) list all modes of acquisition or loss of citizenship in one country (select the country you are interested in); b) compare a mode of acquisition or loss of citizenship across countries (select the mode of acquisition/ loss of citizenship you are interested in and compare across all or selected countries) How to cite the dataset Vink, Maarten, Luuk van der Baaren, Rainer Bauböck, Jelena Džankić, Iseult Honohan and Bronwen Manby (2025).

This version includes corrections of coding for those years covered by previous iterations of the Dataset, drawing on feedback from experts, new information or revised insights into the most appropriate interpretation of specific legal provisions. All updates and corrections are listed in the updated Codebook.
