Welcome to the PPDB Project Home Page!

The Political Party Database Project is a cross-national collaborative initiative to establish a regularly-updated, online, public database as a central source for key information about political party organization, party resources, leadership selection, and political participation within parties.  This project is supported by an international team of experts on political parties. Our aim is to advance the comparative study of political parties as central actors in representative democracies.


Project members initially met at the European University Institute in May 2011 in a working group session sponsored by the European Consortium for Political Research.  Participants have subsequently met at Leiden University in Fall 2011, and at the University of Duesseldorf in Summer 2012 and Fall 2013.   Team members are currently finalizing the initial round of data collection. 


More information about the project can be found in Assessing Party Organizational Change: Participation, Representation and Power, a paper presented at the 2013 American Political Association Meetings.
