General Social Survey
The GSS gathers data on contemporary American society to monitor and explain trends and constants in attitudes, behaviors, and attributes. The GSS contains a standard core of demographic, behavioral, and attitudinal questions, plus topics of special interest. Among the topics covered are civil liberties, crime and violence, intergroup tolerance, morality, national spending priorities, psychological well-being, social mobility, and stress and traumatic events. The GSS is considered one of the single best sources for sociological and attitudinal trend data covering the United States.
