The CSES is a collaborative program of research among election study teams from around the world. Participating countries and provinces include a common module of survey questions in their post-election studies. The resulting data are deposited along with voting, demographic, district and macro/electoral system variables. The studies are then merged into a single, free, public dataset for use in comparative study and cross-level analysis.

The research agenda, questionnaires, and study design are developed by an international committee of leading scholars of electoral politics, political science, and survey research. The design is then implemented in each country and province by their foremost social scientists.
