Comparative Study of Electoral Systems
The Comparative Study of Electoral Systems (CSES) is a collaborative research project among national election studies around the world. Participating countries and polities include a common module of survey questions in their national post-election studies. The resulting data are collated together along with voting, demographic, district and macro variables into one dataset allowing comparative analysis of voting behavior from a multilevel perspective.
The CSES is published as a free, public dataset. The project is administered by the CSES Secretariat, a joint effort between the Institute for Social Research at the University of Michigan and the GESIS – Leibniz Institute for the Social Sciences in Germany.
