The British Election Study, 2005: Comparative Study of Electoral Systems (CSES) dataset forms part of the CSES programme of collaborative research among election study teams from around the world. The research agenda, questionnaires, and study design are developed by an international committee of leading scholars of electoral politics and political science. The design is implemented in each country by leading social scientists. Participating countries include a common module of survey questions in their post-election studies. The resulting data are combined with voting, demographic, district and macro variables, and each country's data is then merged into a single, free, public dataset for use in comparative research. The BES 2005 CSES data were gathered via an internet survey carried out by YouGov plc. The survey was conducted after the 5 May 2005 general election, between 16 and 31 May. Nearly 90% of the interviews were completed between 16 and 18 May. Further information about the international programme may be found on the CSES web site.
