GSS 1972-2018 Cumulative Data File
The 1972-2018 GSS cumulative data file for the National Opinion Research Center’s General Social Surveys (GSS) is available from the Roper Center for Public Opinion Research for immediate download .
These data have been processed by the Roper Center and differ in several ways from the original version supplied by NORC. During the archival process, systematic changes have been made to the data files for completeness.
These changes include:
- Additions and corrections to response labeling
- Inclusion of “Don’t know” responses as valid
- Since a number of variables differ and new variables have been added to the cumulative data file, the codebook frequencies should not be trusted as definitive response distributions.
In 2008 the GSS was in transition from a replicating cross-sectional design to a design that uses rotating panels. There were two components: a new 2008 cross-section with 2,023 cases and the first re-interviews with 1,536 respondents from the 2006 GSS. In 2010 the new design was fully implemented. There is a new cross-section of about 2,044 cases, the first re-interviews of the 2008 GSS respondents, and the second and final re-interviews of the 2006 GSS respondents. This three-wave, rolling panel design was also used in 2012. Each GSS will thus 1) start a new 4-year/3-wave panel, 2) be in the middle of a 4-year/3-wave panel, and 3) finish a still earlier 4-year/3-wave panel.
The National Data Program for the Social Sciences (NDPSS) 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 32nd time in 2018. 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. The exact wording of these questions is retained to facilitate time trend studies as well as replications of earlier findings.
The newly released data file contains individual response coding for 64,814 respondents and 6,108 variables. The 2018 GSS follows the biennial, double sample design that was first adopted in 1994.
Currently, the Principal Investigators are Tom W. Smith, Senior Fellow and Director of NORC's Center for the Study of Politics and Society and Director of the General Social Survey (GSS); Michael Davern, Executive Vice President of Research and Director of Health Care research at NORC; Jeremy Freese, Professor of Sociology at Stanford University, and Stephen Morgan, Bloomberg Distinguished Professor of Sociology and Education at Johns Hopkins University.
Former Principal Investigators include James A. Davis, formerly Director of NORC and now a Senior Lecturer in the Department of Sociology at the University of Chicago; Tom W. Smith, Senior Fellow and Director of NORC's Center for the Study of Politics and Society and Director of the General Social Survey (GSS), and Peter V. Marsden, Research Associate, NORC and Department of Sociology, Harvard University.
The new survey has been added to the cumulative file, which now contains data spanning over 40 years.

GSS 1972-2018 Technical Specifications
The General Social Surveys have been conducted during the first six months of each year. There are a total of 64,814 completed interviews:
The median length of the interview has been about one and a half hours.
GSS Sample Design
- Each survey from 1972 to 2018 was an independently drawn sample of English-speaking persons 18 years of age or over, living in non-institutional arrangements within the United States.
- Starting in 2006 Spanish-speakers were added to the target population.
- Block quota sampling was used in 1972, 1973, and 1974 surveys and for half of the 1975 and 1976 surveys.
- Full probability sampling was employed in half of the 1975 and 1976 surveys and the 1977, 1978, 1980, 1982-1991, 1993-1998, 2000 through 2018 surveys.
- Also, the 2004 through 2018 surveys had sub-sampled non-respondents (see Appendix A for a detailed description of the sample design).
GSS Data Processing
The data from the interviews were processed according to standard NORC procedures.
This cumulative data set merges all 32 surveys into a single file with each year or survey acting as a sub file. This greatly simplifies the use of the General Social Surveys for both trend analysis and pooling. In addition, this cumulative data set contains newly created variables (e.g. a poverty line code). Finally, the cumulative file contains certain items never before available.

GSS Codebook Description
Comprehensive information on all aspects of the General Social Surveys 1972-2018 project. Codebook contains exact question text, response codes and frequency counts for 6,108 variables used by the National Opinion Research Center for over 40 years. While the codebook is intended to be used in conjunction with the General Social Survey 1972-2018 cumulative data file, the codebook alone holds a wealth of opinion data on a wide variety of social issues.
