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 behaviour of voters and candidates. Since its foundation, the GLES has been carried out in close cooperation between the German Society for Electoral Studies (DGfW) and GESIS – Leibniz Institute for the Social Sciences.

Data release
GLES Tracking February 2022, T51 is available

The GLES Tracking allows for the analysis of long-term processes of public opinion formation and change, especially in between parliamentary elections. For this purpose, up to four web-based cross-sections with about 1,000 respondents each are surveyed at regular intervals per year using an online access panel. The datasets can be used to analyze voters' attitudes to the most important political and social issues, to the parties and their leaders, as well as to the performance of the federal government and the opposition.

New publication
Edited volume on the 2009, 2013, and 2017 federal elections published!

Edited by (former) members of the GLES Coordination Group Rüdiger Schmitt-Beck, Sigrid Roßteutscher, Harald Schoen, Bernhard Weßels and Christof Wolf, the president of GESIS, the book "The Changing German Voter" was published by Oxford University Press earlier this week. The book focuses on the drastic changes in electoral behavior between the 2009, 2013 and 2017 federal elections in Germany. It contains 15 chapters with in-depth analyses of German voters' attitudes, beliefs and behavior and impressively demonstrates the analytic potential of GLES data.
