The political effects of intra-EU migration: Evidence from national and European elections in seven countries

This article studies the impact of immigration from Central and Eastern Europe on support for Eurosceptic parties. The analysis covers 30 national and European Parliament elections in seven Western, Northern and Southern European countries (2004 to 2019). For each election, I analyse how the local-level share of the vote for right- and left-wing Eurosceptic parties varies as a function of the levels and changes in the local-level share of Central and Eastern European immigrants from the population, controlling for the influence of relevant demographic, social and economic variables. I find that higher levels of immigration from Central and Eastern Europe are systematically related to higher voting shares cast for right-wing Eurosceptic parties at the local level in all of these countries, net of the influence of non-Western immigration, in elections for the European Parliament and in national elections as well. The effects on left-wing Euroscepticism are heterogeneous: positive in the Netherlands, Austria and Portugal, but negative in Italy, Denmark and Sweden. The effects have not diminished significantly over the past 15 years and are most visible in mid-sized localities.
