Direct Democracy in Switzerland in the 21st Century (DDS21)

Methoden

After each popular vote at the federal level, a cross-sectional online survey is conducted among a random sample of Swiss voters (Swiss citizens aged 18 years and above) taken from the SRPH. At the end of each cross-sectional online survey, respondents are recruited into an online panel survey, with waves after each federal vote. Only respondents with a valid email address are recruited into the feed-in panel survey.
