Welcome!
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.

| New publication Special Issue “GLES Open Science Challenge 2021” released! (Online first) | |
| The GLES Open Science Challenge 2021 was a pioneering initiative in quantitative political science. The project combined the rigor of registered reports—a new publication format in which studies are evaluated prior to data collection/access and analysis—with quantitative political science research in the context of the 2021 German federal election. The special issue, which features seven registered reports that resulted from the project, shows that transparent research following open science principles benefits our discipline and substantially contributes to quantitative political science. All contributions are based on GLES data and are available open access. (15.12.2022) |  |
