Swiss voting age population (age 18 and over)

Random sampling. The sample in wave 1 consists of 2633 respondents. Participants who answered the first wave were recontacted in the next two waves. In wave 4 and 5, only respondents who answered the previous wave were recontacted. Wave 5 also includes a refreshment sample.

The final data includes survey weights based on language region, age, gender, and party affinity in order to ensure representativeness.

Working-age respondents (aged 18–69) from all EU member states

The data were collected by placing questions on an EU-wide online survey omnibus (the “EuroPulse”) that was regularly conducted by Dalia Research. In each wave, the sample consists of a census representative sample of approximately 10’000 working- age respondents (aged 18–69) from all EU member states, with sample sizes roughly proportional to their population size. While the overall sample is representative of the EU population, samples from France, Germany, Italy, Poland, Spain, and the UK are also nationally representative.

The final data includes weights based on language region, age, gender and party affinity in order to ensure representativeness.
