Our goals and services

Our goal is to provide academics, governments, international organisations and NGOs with information for research and evidence-based evaluation of public policies.

We do not offer information or counselling to individuals interested in acquiring the citizenship of a particular country and we do not encourage experts in our network to answer such requests.

Where to find what
Let us briefly introduce you to some of the main features of this webpage. Through the right hand side menu you can access our databases, while the left hand side menu publishes analyses written for our observatory. The country profile and European citizenship pages also contain links to relevant data and documents in our databases.
 
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.
 
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.
 
CITIZENSHIP NEWS collects online news articles about political debates, legislative reforms or other matters concerning citizenship. The most recent entries are also displayed on the right margin of this front page. On the Citizenship News page you can search our media archive for older contributions.
 
CITIZENSHIP FORUM is a platform for debate about research hypotheses or political questions concerning the acquisition and loss of citizenship. We invite academic scholars, NGOs and policy makers to introduce their ideas in a broadly accessible comment or to respond to previous contributions.
 
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.
 
On the right hand side menu you can search three databases containing legal documents:
 
The NATIONAL CITIZENSHIP LAWS page collects not only current and past nationality laws, but also decrees, constitutional provisions and other relevant legal texts.
 
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.
 
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.
 
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 horizontal menu at the top of our website provides you with information about our project, the people who have contributed to EUDO CITIZENSHIP, a selection of recent major publications on our research topics, a documentation of past EUDO CITIZENSHIP conferences and other events, announcements of forthcoming events, a page with testimonials of scholars and policy-makers who have found our website useful, and information how you can contact us.
