The website is about the Comparative Study of Electoral Systems (CSES), a collaborative program that conducts research among election teams from different countries. The site provides information on various aspects of the CSES program, such as home, data collection and download, election studies, variable table, turnout, vote choice data overview, results bibliography, and more. It also highlights the 25th anniversary special issue of the Klingemann Prize and an Oxford University Press book series related to CSES. Visitors can find frequently asked questions, updates from the CSES secretariat, and a blog on the website. The research modules conducted by CSES focus on topics like electoral institutions' impact on political behavior and cleavages alignments in democratic processes. They also study accountability and engagement in relation to representative institutions and decision-making processes within different institutional contexts. Finally, they explore perceptions and assessments regarding political choices made during elections and examine how meaningful alternatives are provided by political systems.
