European Parliament Election Study 2019, Voter Study

The 2019 European Election Study (EES) Voter Study is a post-election study, conducted in all 28 EU member states after the elections to the European Parliament were held between 23 and 26 May 2019. The main objective of the 2019 EES Voter study is to study electoral participation and voting behaviour in European Parliament elections, but more than that. It is also concerned with the evolution of an EU political community and a European public sphere, with citizens’ perceptions of and preferences about the EU political regime, with their evaluations of EU political performance, and the consequences of Brexit.

The survey was conducted by Gallup International. The data collection was mostly conducted online. The respondents were selected randomly from access panel databases using stratification variables, with the exception of Malta and Cyprus where a multi-stage Random Digit Dialing approach was used. In all countries, the samples were stratified by gender, age, region and type of locality. The sample size is roughly 1,000 interviews in each EU member state (except Cyprus, Luxembourg and Malta where the sample size is 500). The total sample size is 26,538.

The questionnaire covers items on electoral behavior, such as questions on electoral participation and party choice at the EU and national level, party preferences, and propensity to support particular parties; general political attitudes; interest in politics; background characteristics such as gender, age, education, religion. Innovations in EES 2019 include batteries of questions about the consequences of Brexit and on liberal democratic attitudes.
