General Social Survey Series
The National Data Program for the Social Sciences (General Social Survey) is both a data diffusion project and a program of social indicator research. Its data collection instrument, the General Social Survey (GSS), was fielded for the 29th time in 2012. Previously an annual survey, the GSS became biennial in 1994. The questionnaire contains a standard core of demographic and attitudinal variables, plus certain topics of special interest selected for rotation (called "topical modules"). Items that appeared on national surveys between 1973 and 1975 are replicated.
