UniverseThe population comprises all Germans who were eligible to vote German Bundestag. Due to the fact that the study was conducted online, not everybody had a chance to get selected for this survey. Therefore population comprises only members of the LINK Internet Panel who are at least 18 years old, are German citizens, live in Germany and use the Internet for private purposes at least once a week. This population comprises at sampling time nearly 40000 active panel members. Recruitment of panel members was exclusively done by phone.

  •  German Longitudinal Election Study (GLES)
    The German Longitudinal Election Study (GLES) is a DFG-funded project which made its debut just prior to the 2009 federal election. GLES is the largest and most ambitious election study held so far in Germany. Although the initial mandate is to examine and analyse the electorate for three consecutive elections, the aspired goal is to integrate the project within GESIS as an institutionalized election study after the federal election of 2017, and hence to make it a permanent study.
