Geographic Coverage
  • Germany (DE)
UniverseThe population comprises all German citizens who were eligible to vote in the German federal election when the survey was conducted, i.e. all persons with German citizenship who had reached the age of 18 at the time the study was carried out. Due to the fact that this was an online survey not everybody who was eligible to vote had a chance to get selected for this Online Tracking. Therefore the frame population comprises only active participants of the Online-Access-Panel conducted by Respondi AG who were German citizens and who had reached the age of 18. The Respondi panel contained 65,000 to 70,000 members at the end of 2016. After completing a double opt-in registration procedure and filling in their master data, Respondi panel members are considered active, when they participated in at least one survey in the past three months.

Errata in current version
2020-4-21Error in time variables zstart-zendThe time that respondents needed to view and edit the single pages of the survey is calculated from the cumulated times recorded by the server. Due to unknown reasons, the time was incorrectly recorded on some pages. If this made the correct calculation of the time variables zstart-zend impossible, the time for viewing and editing a page was coded as -92 "Error in data".

  •  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.
