General Social Survey  "The General Social Survey (GSS) conducts basic scientific research on the structure and development of American society with a data-collection program designed to both monitor social change within the United States and to compare the United States to other nations. The GSS contains a standard 'core' of demographic, behavioral, and attitudinal questions, plus topics of special interest. Many of the core questions have remained unchanged since 1972 to facilitate time-trend studies as well as replication of earlier findings." (from the GSS website) Data access is provided through the GSS website and ICPSR.

Health and Retirement Study  "The Health and Retirement Study (HRS) is a source of longitudinal, cross-sectional data for researchers and policymakers who study aging.

IPUMS USA This is a project dedicated to collecting and distributing United States census data. The resources here allow you to make subsets of US Census data across censuses and for selections of variables or geography. "The Integrated Public Use Microdata Series (IPUMS) consists of thirty-nine high-precision samples of the American population drawn from fifteen federal censuses and from the American Community Surveys of 2000-2006. Some of these samples have existed for years, and others were created specifically for this database. The thirty-nine samples, which draw on every surviving census from 1850-2000, and the 2000-2006 ACS samples, collectively comprise our richest source of quantitative information on long-term changes in the American population."

IPUMS International As with the IPUMS USA this project aims to make available census data from countries around the world. Census files are currently available for 35 countries.

National Longitudinal Study of Adolescent Health (Add Health) "is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-95 school year. The Add Health cohort has been followed into young adulthood with four in-home interviews, the most recent in 2008, when the sample was aged 24-32. Add Health combines longitudinal survey data on respondents’ social, economic, psychological and physical well-being with contextual data on the family, neighborhood, community, school, friendships, peer groups, and romantic relationships, providing unique opportunities to study how social environments and behaviors in adolescence are linked to health and achievement outcomes in young adulthood. The fourth wave of interviews expanded the collection of biological data in Add Health to understand the social, behavioral, and biological linkages in health trajectories as the Add Health cohort ages through adulthood." (from the Add Health website) Data access is provided by ICPSR and Sociometrics.
