Federal Data Resources

America FactFinder -- A source for population, housing, economic, and geographic data.

American National Election Studies  -- The American National Election Studies (ANES) produces high quality data on voting, public opinion, and political participation to serve the research needs of social scientists, teachers, students, policy makers and journalists who want to better understand the theoretical and empirical foundations of national election outcomes. Central to this mission is the active involvement of the ANES research community in all phases of the project.

Data.Gov -- The purpose of Data.gov is to increase public access to high value, machine readable datasets generated by the Executive Branch of the Federal Government. Data.gov provides descriptions of the Federal datasets (metadata), information about how to access the datasets, and tools that leverage government datasets. The data catalogs will continue to grow as datasets are added. Federal, Executive Branch data are included in the first version of Data.gov.

Fed Stats -- Fed Stats provides information for Federal agencies that are listed in Statistical Programs of The United States Government and reporting expenditures of at least $500,000 per year in one or more statistical activities.

General Social Survey -- 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. The GSS takes the pulse of America, and is a unique and valuable resource. It has tracked the opinions of Americans over the last four decades.

Health and Retirement Study -- The University of Michigan Health and Retirement Study (HRS) surveys more than 22,000 Americans over the age of 50 every two years. Supported by the National Institute on Aging (NIA U01AG009740) and the Social Security Administration, the HRS is a large-scale longitudinal project that studies the labor force participation and health transitions that individuals undergo toward the end of their work lives and in the years that follow. Since its launch in 1992, the study has collected information about income, work, assets, pension plans, health insurance, disability, physical health and functioning, cognitive functioning, and health care expenditures. Through its unique and in-depth interviews with a nationally representative sample of adults over the age of 50, the HRS provides an invaluable, growing body of multidisciplinary data to help researchers address the challenges and opportunities of aging.

The Interuniversity Consortium for Political and Social Research -- ICPSR provides leadership and training in data access, curation, and methods of analysis for a diverse and expanding social science research community.

National Academies’ Committee on National Statistics -- To improve the statistical methods and information on which public policy decisions are based, CNSTAT works to foster state-of-the-art data collection and estimation methods for a wide range of federal statistical activities, to further the application of statistics to better implement and evaluate federal programs, and to strengthen the development and accessibility of data for social, economic, and other scientific research. Every 4 years it publishes the influential volume, Principles and Practices for a Federal Statistical Agency

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.

Panel Study of Income Dynamics -- The Panel Study of Income Dynamics (PSID), begun in 1968, is a longitudinal study of a representative sample of U.S. individuals (men, women, and children) and the family units in which they reside. It emphasizes the dynamic aspects of economic and demographic behavior, but its content is broad, including sociological and psychological measures. As a consequence of low attrition rates and the success in following young adults as they form their own families and recontact efforts (of those declining an interview in prior years), the sample size has grown from 4,800 families in 1968 to more than 7,000 families in 2001. At the conclusion of 2003 data collection, the PSID will have collected information about more than 65,000 individuals spanning as much as 36 years of their lives. The study is conducted at the Survey Research Center, Institute for Social Research, University of Michigan and has been made possible through the generous Sponsorship of government agencies, foundations, and other organizations over the years.  Since 1982, the study has had an advisory Board of Overseers, appointed by the NSF to foster input from the national community of scholars, researchers, and policy makers. The study is currently directed by a team of Principal Investigators

Medical Expenditure Panel Survey - MEPS is a set of large-scale surveys of families and individuals, their medical providers (doctors, hospitals, pharmacies, etc.), and employers across the United States. MEPS collects data on the specific health services that Americans use, how frequently they use them, the cost of these services, and how they are paid for, as well as data on the cost, scope, and breadth of health insurance held by and available to U.S. workers. It is the most complete source of data on the cost and use of health care and health insurance coverage. MEPS currently has two major components: the Household Component and the Insurance Component. The Household Component provides data from individual households and their members, which is supplemented by data from their medical providers. The Insurance Component is a separate survey of employers that provides data on employer-based health insurance.

Health.Data.Gov - Health.Data. Gov is a public resource designed to bring together high-value datasets, tools, and applications using data about health and health care. The datasets and tools have been gathered from agencies across the Federal government.
