German Longitudinal Election Study
The German Longitudinal Election Study is a large-scale panel and cross-sectional survey program focused on electoral behavior, public opinion, and political communication in Germany. It integrates survey research, experimental designs, and digital trace data to analyze voting patterns and party competition across federal elections such as the 2013 German federal election, 2017 German federal election, and 2021 German federal election. The study is situated within German and comparative research networks including institutions like the Wissenschaftszentrum Berlin für Sozialforschung, University of Mannheim, and the German Research Foundation.

Launched in the early 2010s, the project evolved from earlier German election studies linked to institutions such as the German Longitudinal Election Study (predecessors), the Bundeszentrale für politische Bildung, and international collaborations with the Comparative Study of Electoral Systems, the European Social Survey, and the British Election Study. Founders and leading scholars associated with the initiative include academics from the University of Mannheim, University of Konstanz, Wissenschaftszentrum Berlin für Sozialforschung, Hertie School, Free University of Berlin, Humboldt University of Berlin, Leipzig University, University of Cologne, University of Bonn, University of Bremen, University of Münster, Goethe University Frankfurt, Technical University of Munich, University of Hamburg, University of Göttingen, Saarland University, Johannes Gutenberg University Mainz, University of Tübingen, University of Erlangen-Nuremberg, University of Hamburg's Hans-Bredow-Institut and linked survey centers like GESIS – Leibniz Institute for the Social Sciences.
The methodological design employs probability samples, quota samples, and online panels using instruments developed by methodologists influenced by figures such as Rensis Likert, Paul Lazarsfeld, Gabriel Almond, Sydney Verba, Robert Putnam, Theodore Lowi, Stanley Hoffmann, Elinor Ostrom, James Coleman, Charles Tilly, Giovanni Sartori, Seymour Martin Lipset, Herbert A. Simon, Donald Campbell, Robert M. Hauser, and technical standards from organizations like the American Association for Public Opinion Research, European Consortium for Political Research, and International Social Survey Programme. Data collection mixes face-to-face interviews, telephone surveys, and web-based data streams while incorporating experimental modules inspired by designs used in studies with actors such as Barack Obama, Bill Clinton, Margaret Thatcher, Tony Blair, Emmanuel Macron, François Hollande, Nicola Sturgeon, Pedro Sánchez, Giuseppe Conte, Matteo Renzi, Sergio Mattarella, Andrzej Duda, Vladimir Putin, Recep Tayyip Erdoğan, Narendra Modi, Justin Trudeau, Jacinda Ardern, Scott Morrison, Boris Johnson, Keir Starmer, Alexis Tsipras, Pablo Iglesias, Marine Le Pen, Jean-Luc Mélenchon, Sergio Fajardo.
