About Us

The Constituency-Level Elections Archive (CLEA) is a repository of detailed election results at the constituency level for lower house legislative elections from around the world. Our motivation is to preserve and consolidate these valuable data in one comprehensive and reliable resource that is ready for analysis and publicly available at no cost. This public good is expected to be of use to a range of audiences for research, education, and policy-making.

Award

CLEA was selected to receive the 2012 Lijphart/Przeworski/Verba Data Set Award for the best data set in comparative politics.
