Welcome to The Representative Democracy Data Archive (REPDEM)

REPDEM presents the comparative data collection efforts undertaken by various research and data infrastructure projects on governments, parliaments, political parties, length of government formation periods, bargain rounds, as well as procedures and mechanism for intra-coalition governance in Europe.
Here we offer a range of open-access datasets (available for free). Please select one of the projects to download data and supporting documentation.
The Representative Democracy Data Archive (REPDEM) builds on the European Representative Democracy Archive (ERDDA), but will include countries outside of Europe as well.
