General Social Survey
The GSS has been conducted since 1972 by the National Opinion Research Center. It measures attitudes toward social and public policy issues, economic status, political events, work, and family life. Some questions are asked each year, and topical modules are administered on a rotating basis that focus on current topics such as gender equity, religious beliefs, and perception of work. The 1972-2006 file was released in May 2007.
The Survey Documentation and Analysis (SDA) software at UC Berkeley allows you to construct tables from the 1972-2006 cumulative file based on variables you select, perform custom extracts, and create and recode variables. The NORC site has a similar data analysis tool using the NESSTAR software. You can use recent GSS years from the Association of Religion Data Archives, view responses to individual questions crosstabulated by respondent categories, and view frequencies using spiffy graphics. (CISER has the GSS data files on its server.)
