Our new GLOBALCIT website is under construction. In the meantime, please use the current website as before.

Where to find what

Let us briefly introduce you to some of the main features of this website. All the information provided by EUDO CITIZENSHIP is accessible through the left hand side menu. The quicklinks on the right hand side give you direct access to the most frequently used pages.

The pages ABOUT provides you with information about the people who have contributed to EUDO CITIZENSHIP, announcements of forthcoming events, a documentation of past EUDO CITIZENSHIP conferences and other events, a page with testimonials of scholars and policy-makers who have found our website useful, the project's funding, the related projects and information on how you can contact us.

On the COUNTRY PROFILES pages you will find comprehensive expert reports on the history and current citizenship legislation in the countries covered in our project, as well as a the text of citizenship laws and international legal documents to which this country adheres. Moreover, we have collected relevant court decisions, academic publications and links to organisations concerned with citizenship matters.

The page on EUROPEAN UNION CITIZENSHIP collects analyses and original documents on legal norms, court decisions and policy documents concerning the status and rights of citizenship in the EU, focusing on the impact of EU citizenship on national citizenship.

The section DATABASES collects seven different databases on citizenship:

  • The NATIONAL CITIZENSHIP LAWS page collects not only current and past nationality laws, but also decrees, constitutional provisions and other relevant legal texts.
  • The CITIZENSHIP CASE LAW page provides English summaries and full texts in original language of important national, European or international court decisions concerning matters of citizenship and can be searched by country, year, institution or keyword.
  • On the INTERNATIONAL LEGAL NORMS page you may search either for specific international legal documents to see which countries have signed or ratified these, or you can find out which international norms a particular country has subscribed to.
  • Our databases on MODES OF ACQUISITION and MODES OF LOSS OF CITIZENSHIP have been created from answers by our network experts to questionnaires about specific provisions in their countries’ citizenship laws. A main goal of our observatory is to make legal rules for acquiring or losing citizenship comparable across countries. For this purpose we have created a typology of 27 modes of acquisition and 15 modes of loss that captures most of the broad variety of legal regulations that we find in different countries. This feature of EUDO CITIZENSHIP allows you to create your own comparative overviews for specific ways of acquiring or losing citizenship status.
  • Most countries collect statistics only on naturalisation, not on acquisition of citizenship at birth or on loss of citizenship. Our CITIZENSHIP STATISTICS page provides information on the quality of national statistical data and allows you to create your own statistical tables by choosing countries, years, or specific modes of acquisition.
  • CITIZENSHIP LINKS gives you access to the websites of national, European and international organisations (both governmental and non-governmental), leading academic research centres, networks, projects and journals dealing with citizenship.
  • Our CITIZENSHIP BIBLIOGRAPHY collects academic publications on citizenship, with a focus on the nationality laws of the states covered in our observatory. It includes hyperlinks to full texts available online. You can do a bibliographic search according to various criteria and also import specific items or the whole bibliography to your computer.
  • For the purpose of comparing citizenship laws that often use very different terms for similar legal rules, we have created our own CITIZENSHIP GLOSSARY. Apart from offering our own definitions we also provide on this page translations of the words “citizenship” and “nationality” into the official languages of the countries we observe and brief explanations by our network experts how these concepts are used in national laws and political debates.
  • The PROTECTION AGAINST STATELESSNESS page provides information about the extent to which national citizenship laws provide sufficient protection against statelessness, based on the relevant international legal standards, such as those of the 1954 Convention Relating to the Status of Stateless Persons and the 1961 Convention on the Reduction of Statelessness.

The CITIZENSHIP INDICATORS page presents separate sets of indicators that EUDO CITIZENSHIP is currently constructing. Systematic comparison of citizenship across a large number of countries requires condensing qualitative information into indicators that can be used for quantitative analysis. The wealth of data collected by EUDO CITIZENSHIP allows a much more fine-grained analysis of legal provisions (Citizenship Law Indicators), administrative procedures (Implementation Indicators), statistical developments and integration effects of citizenship acquisition than previously possible (Acquisition Indicators and Integration Indicators).


The PUBLICATIONS pages will provide you access to significant publications related to citizenship:
  • COUNTRY REPORTS leads you to our COUNTRY PROFILES pages where you can find expert reports on the history and current citizenship legislation in the countries covered in our project.
  • COMPARATIVE CITIZENSHIP ANALYSES displays our legal and social science experts’ analyses of European trends. Several reports focus on specific modes of acquisition, such as ius soli, naturalisation or extraterritorial acquisition of citizenship.
  • Our WORKING PAPER series collects original academic analyses on citizenship in Europe that have not been specifically commissioned by our project and have not yet been published elsewhere. 
  • In our POLICY BRIEFS we summarise major findings of our comparative research and policy recommendations in a non-technical language.
  • RECENT PUBLICATIONS displays a selection of recent major publications on our research topics.

In the NEWS section, you will find the CITIZENSHIP NEWS page which offers a selection of media reports and news summaries on significant legislative changes, court decisions, policy developments, political campaigns or other events concerning citizenship in Europe and beyond. Information on important events or publications related to citizenship can be found in the section ANNOUNCEMENTS.

Finally, the COMMENTARIES page gives you access to two online platforms where researchers, policy-makers and NGOs can submit comments: the CITIZENSHIP FORUM invites comments written specifically for the EUDO CITIZENSHIP website on a specific question of general and long-term interest and the VIDEO COMMENTS page collects short video statements on current citizenship news and documents presentations at EUDO CITIZENSHIP events.
