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.

PolDem Database

The Observatory for Political Conflict and Democracy (PolDem) is a platform that produces and houses data on protest events, election campaigns, and issue-specific public contestation covering a wide-range of European countries over a long period of time.

PPEG Database

The PPEG Database contains information on political parties, presidents, elections, and governments around the world. It brings together a range of datasets produced by the department "Democracy & Democratization" of the WZB Berlin Social Science Center. Our goal is to provide a comprehensive resource of election and government information for research, education, and policy-making. The current version of the database covers information from 72 countries in Africa, the Americas, Asia, Australia, and Europe between 1945 and 2021 including data on 3.030 political parties, 1.011 parliamentary elections, 338 presidential elections, and 1.881 cabinets.



Protestdatabase PRODAT

The database records protest events in the German Federal Republic. It is based on a random sample of reporting in the Frankfurter Rundschau and the Süddeutsche Zeitung. Currently, a dataset suitable for analysis is available for the period from 1950 to 2002. From 1989 onwards, it includes protests in the GDR respectively in the New Federal States.




The databank-based website documents networks of policy-related research and consulting institutes in Europe, as well as institutes for the marketing of ideas, and political advocacy and opinion making. Information about individuals, financing, publications, events and other activities will also be compiled and documented. The website offers expanded analyses, graphic depictions and research tools.
