German Longitudinal Election Study (GLES)


The German Longitudinal Election Study (GLES) is the central survey program in Germany for the continuous collection and provision of high-quality data for national and international election research. The methodologically diverse surveys of the GLES make it possible to investigate the political attitudes and behavior of eligible voters and candidates. Since its foundation, the GLES has been conducted in close cooperation between the German Society for Electoral Studies (DGfW) and GESIS – Leibniz Institute for the Social Sciences.


An overview over the GLES Data can be found under Data and Documentation.
