A cornerstone of European integration, the freedom to work and live anywhere within the European Union is possibly the most visible and cherished perk of EU citizenship. However, for several years the freedom of movement has been the source of a contentious debate, featuring prominently in the rhetoric of Eurosceptic parties re-shaping the political landscape and the EU’s ongoing negotiations over the United Kingdom’s exit from the union in March 2019. In their article “Opportunity or threat? Public attitudes towards EU freedom of movement” published in the Journal of European Public Policy, Sofia Vasilopoulou and Liisa Talving explore the drivers of the public’s attitudes towards intra-EU migration. Combining evidence from four waves of Eurobarometer surveys administered between 2015 and 2017, Sofia and Liisa’s analysis shows that respondents with low levels of skills and education as well as those holding strong feelings about national identity are the ones most likely to oppose freedom of movement. These findings need to be evaluated in a domestic context, however. Digging a little deeper, Sofia and Liisa show that individual-level factors are clearly moderated by country affluence, with generally high levels of support for intra-EU migration in poorer EU member states, even among respondents typically perceived as Eurosceptic. Crucially, Sofia and Liisa’s analysis highlights that “[c]itizens in richer countries that tend to receive more EU migrants and where the question of EU mobility is more salient seem to be more prone to perceiving EU freedom of movement as a threat.”
