Parliament and government composition database

Research project

ParlGov (Parliament and government composition database) is a database infrastructure that provides information on party positions, election results and government composition. The project is lead by Holger Döring and Philip Manow of the University of Bremen – Centre for Social Policy Research (ZeS). Work on the project started in 2005 at the Max Planck Institute for the Study of Societies (MPIfG) in Cologne. It was later based at the University of Konstanz (2007–2009), the European University Institute (2009/10), the University of Heidelberg (2009/10) and the Centre for Social Policy Research, University of Bremen (2010–today).
