German Longitudinal Election Study (2009–2017)

This long-term study of three consecutive federal elections (in 2009, 2013 and 2017) seeks to examine the behavior of voters, as well as the context in which they make their decisions (parties, candidates, election campaign, mass media). Horizontal and longitudinal surveys are combined with a survey about the candidates, as well as analyses of TV debates and media coverage. The data sets are available for free download; use of the candidates survey requires agreeing to the user regulations.
