Methodology

Geographic Coverage
  • Germany (DE)
UniverseThe population comprises all German citizens who were eligible to vote when the survey was conducted. Due to the fact that this was an online survey not everybody who was eligible to vote had a probability to get selected for this Online Tracking. Therefore the population comprises all persons with German citizenship resident in the Federal Republic of Germany and being part of the forsa omninet, who had a minimum age of 18 years, who lived in Germany and used at least once a week the Internet for private reasons. This group comprised nearly 75000 active Panel members. Active Panel members had been recruited exclusively by phone, had filled out a basic questionaire and had attended to at least one survey within the last twelve months.

DateSubjectDescription
2017-11-2Programming error t920Due to a programming error respondents were given the possibilty to check more than one answer instead of just one. Eventually, only one respondet named more than one party. Thus, the answers were able to be combined into on variable, following the party variable schema of version A and B.
2017-11-2Shortend time of collectionDue to a technical problem regarding the invitation to the survey the survey had to be restarted. Therefore, compared to former long-term online trackings the time of collection is shorter.

  •  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.
