Parties, Institutions and Preferences (PIP)

Our PIP-data sets provide detailed information about political parties, institutions (e.g. 1st and 2nd chambers) and the preferences of political actors. Specific indicators suitable for Time-Series—Cross-Sectional (TSCS) data analysis have been developed by a research team of the University of Greifswald. The data cover important aspects of macro-comparative politics and were compiled from other data sources in the political sciences.
