Geographic Coverage
  • Germany (DE)
UniverseThe population of the GLES tracking consists of citizens of the Federal Republic of Germany who were eligible to vote in elections to the German Bundestag at the time of the survey, i.e. German citizens who had reached the age of 18 at the time of the survey. Since the data was collected using computer-aided web interviews (CAWI), not all citizens who were eligible to participate also had a chance different from zero of being selected for the survey. The frame population therefore only includes active participants in the Online-Access-Panel operated by respondi AG who were German citizens and who had reached the age of 18 at the time the study was conducted.

Errata in current version
2020-7-15Programming error: t308pDue to a programming error, no valid entries could be collected here, so the values of all respondents on this variable were coded as -92 "Error in data".
2020-7-15Error 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.
