Democracy is government accountable to citizens. But how do states determine who their citizens are? Are you interested in the history and current regulation of citizenship in a particular country? Do you want to compare citizenship acquisition by birth or naturalisation across several European states? Do you need information about current international legal norms on multiple nationality or statelessness? Do you want to analyse statistical trends of naturalisation? On this website you will find the best information currently available for the EU member states and neighboring countries.

“EUDO Citizenship Observatory is a key tool for thinking about future prospects of European citizenship and developing evidence-based policy making in the EU’s Area of Freedom, Security and Justice”

EUDO CITIZENSHIP provides information on acquisition and loss of citizenship in Europe for policy makers, NGOs and academic researchers. It is part of a larger European Union Democracy Observatory, hosted at the Robert Schuman centre for Advanced Studies.

This website is built by a network of experts all across Europe and a consortium of five partner institutions. The European Fund for the Integration of Third Country Nationals has provided financial support for the project.

EUDO CITIZENSHIP contributes to understanding current trends in citizenship policies. Although the observatory does not promote specific policy reforms, it intends to stimulate debates about shared principles and minimum standards among countries whose citizenship laws and policies are linked to each other through the common citizenship of the European Union or through migration flows.

Please note that the observatory is a work in progress and several pages of the website are still under construction. Although we make every effort to check the information made available here, we cannot exclude the possibility of occasional errors. We are happy to receive your feedback, contributions, and comments.
