Comparative Citizenship Analyses

A primary goal of EUDO CITIZENSHIP is to stimulate comparative analyses of citizenship laws and policies. Until recently, most such analyses were either based on in-depth case studies of very small few (mostly Western European) countries, or on a superficial classification of a larger set of countries based on selected indicators such as waiting periods for naturalisation, ius soli provisions or the toleration of dual citizenship. Based on the methodology of the earlier NATAC project, EUDO CITIZENSHIP provides systematic information on all major modes of acquisition and loss of citizenship for all EU member states and a substantial number of neighbouring countries as well as in-depth analyses of the history and contemporary context of citizenship legislation.

These comprehensive sources of information have been used for a series of comparative reports commissioned by EUDO CITIZENSHIP which are posted on this page as they become available.

In addition to analyses of specific modes of acquisition and loss of citizenship for all countries covered by EUDO Citizenship, we have also commissioned regional reports. EUDO Citizenship expert Giovanna Zincone coordinates a series of reports on citizenship policy-making in Mediterranean member states of the European Union (Portugal, Spain, Italy and Greece). The EUDO Citizenship team at the Central European University in Budapest has provided a report on The Politics of External Kin-State Citizenship in East Central Europe.

We encourage researchers from outside our network to use our data bases and reports for their own comparative analyses and to submit these for publication in our Working Paper series.
