British Election Study (BES)

The British Election Study (BES) series is the longest academic series of nationally representative probability sample surveys in the country. Its purpose is to investigate the changing elements of electoral behaviour in modern Britain and has been conducted after every general election since 1964. As a research project, the British Election Study has 3 general aims:

• to collect data with a view to describing and explaining the outcome of general elections
• to analyse long-term changes of political attitudes and behaviour from the early 1960's to the present
• to organise and make available these data in a form suitable for a wide range of research.

The results of the 2015 British Election Study are available at http://www.britishelectionstudy.com/ .

Besides the main election surveys, other datasets have also been produced. For example, some studies have included separate sub-samples for ethnic minorities and areas such as Scotland and Northern Ireland (held at the UK Data Archive), and several inter-election panel studies have been undertaken between 1969 and 2001 that follow the same individuals interviewed in the cross-sectional surveys:

• British Election Study, 1974-1983 (BES):

The BES was started as a research project at the University of Essex in 1974, to continue the series started by Butler and Stokes. The BES conducted interview surveys following the general elections of February 1974, October 1974 and May 1979. This series also includes a questionnaire survey conducted after the referendum on Britain's membership of the European Economic Community (EEC) in 1975.

• British General Election Study, 1983-1997 (BGES):

From 1983, the series continued under a slightly changed name conducted jointly by Social and Community Planning Research (SCPR - now the National Centre for Social Research, or NatCen) and Nuffield College Oxford. Prior to 1992 BGES surveys excluded electors living in the five constituencies in the Scottish highlands and islands north of the Caledonian Canal because the small and scattered electorate there could not be interviewed cost-effectively. In the 1992 BGES survey however, these constituencies were included in the sampling frame. Users should note that the Scottish element of the 1992 survey has been down-weighted to form a representative British sample. Researchers wishing to analyse the Scottish sample separately should order SN 3171 General Election in Scotland. The 1997 studies were carried out by the Centre for Research into Elections and Social Trends (CREST) in collaboration with Pippa Norris of Harvard University, the Gatsby Charitable Foundation and the Commission for Racial Equality.
