Following the first two Belgian National Election Studies, which were held after the General Election of 24 November 1991 and 21 May 1995, a third, similar study was set up in connection with the General Election of 13 June 1999. The Study was supported financially by the Federal Services for Technical, Cultural and Scientific Affairs, under the National Ministry of Science. Similar to the first two General Election Studies, this third study focuses on general political attitudes and behavior. Data has been collected on political information and knowledge, perceptions of political bodies such as parties, and perceptions of problems and important issues. Other questions deal with party identification, party preferences, feelings of political efficacy, and the nature and extent of political participation. Perceptions of social class and (economic) well-being, authoritarian attitudes, attitudes to immigrant workers, political corruption and the environment are some of the other areas investigated in this study. Extensive demographic data on the respondents and their families have also been collected.
