General Social Surveys (ICPSR Studies 2685, 6217, 6492, and others) The General Social Survey has been conducted by the National Opinion Research Center annually since 1972 except for the years 1979, 1981, and 1992. Each year the Roper Center for Public Opinion Research prepares a cumulative dataset that merges previous years of the General Social Survey into a single file, with each year or survey constituting a subfile. The content of each year's survey changes slightly as some items are added to or deleted from the interview schedule. Main areas covered in the GSS include socioeconomic status, social mobility, social control, the family, race relations, sex relations, civil liberties, and morals. Topical modules designed to investigate new issues or to expand the coverage of an existing subject have been part of the GSS since 1977. The 1993 topical module concerned cultural issues. Other topics covered have included work organizations (1991); role of government (1990); work orientation (1989); religious socialization, behaviors, and beliefs (1988); sociopolitical participation (1987); the feminization of poverty (1986); social networks (1985); and the role of the military (1982 and 1984). The GSS also added a cross-national component in 1985 through participation in a multinational collaborative group called the International Social Survey Program (ISSP), which includes Great Britain, Germany, Italy, and Austria. Topics addressed are role of government (1985 and 1990); social support (1986); social inequality (1987); the impact on the family of the changing labor force participation of women (1988); work orientation (1989); the impact of religious background, behavior, and beliefs on social and political preferences (1991); and environmental issues (1993). The universe for the GSS is English-speaking persons 18 years of age or over, living in noninstitutional arrangements within the United States. A National Opinion Research Center national probability sample is employed. Block quota sampling was used in 1972-1974 and for half of the 1975 and 1976 surveys. Full probability sampling was employed in the other half of the 1975 and 1976 surveys and for the surveys thereafter.
