This report gives an overview of the obstacles to political participation among mobile European Union (EU) citizens – people holding the citizenship of one Member State who have used their freedom of movement rights to live or work in another. It focuses on how their non-citizenship status in their country of residence, and external status relative to their country of citizenship, affects their ability and propensity to take part in elections in both countries. Drawing on an extensive body of research conducted for the FAIR-EU project, funded by the European Union’s Rights, Equality and Citizenship Programme (2014-2020), the report summarises and synthesises the findings of other FAIR-EU reports to give an overview of the obstacles to electoral participation amongst mobile EU citizens, and the extent to which these impede their propensity to vote and participate in public life.
