ICPSR: Inter-University Consortium for Political and Social Research


The Inter-University Consortium for Political and Social Research (ICPSR), established in 1962, maintains and provides access to a vast archive of social science data for research and instruction, and offers training in quantitative methods to facilitate effective data use. The ICPSR archive offers a large number of data sets on social attitudes, opinions, and behaviors, as well as census and other statistical sources.

The University of Arkansas is a member of ICPSR; current students, faculty, and staff any access and download ICPSR data sets. To download data sets and code books, you will need to create a personal account on the ICPSR site with your UARK email address and a password of your choosing.

ICPSR also hosts a number of partner projects and archives, including:

Child Care and Early Education Research Connections

RC promotes high quality research in child care and early education and the use of that research in policy making. Our vision is that children are well cared for and have rich learning experiences, and their families are supported and able to work. Through this Web site, we offer research and data resources for researchers, policy makers, practitioners, and others.


CrimeStat is a spatial statistics program for the analysis of crime incident locations, developed by Ned Levine & Associates under the direction of Ned Levine, PhD, that was funded by grants from the National Institute of Justice. The program is Windows-based and interfaces with most desktop GIS programs. The purpose is to provide supplemental statistical tools to aid law enforcement agencies and criminal justice researchers in their crime mapping efforts. CrimeStat is being used by many police departments around the country as well as by criminal justice and other researchers. The new version is 3.0 (CrimeStat III).

Health and Medical Care Archive (HMCA)

HMCA is sponsored by the Robert Wood Johnson Foundation, the largest health care philanthropy organization in the United States. HMCA is the official data archive of the Foundation, and is devoted to preserving and making available research data that have significant secondary-analytic value for expanding knowledge on, and ultimately contributing to, improvement of the health of people in the United States.

Homicide Research Working Group (HRWG)

HRWG, an interdisciplinary and international association of researchers and policy makers, was formed in 1991 to foster communication, coordination, and networking among people involved in the study of homicide. ICPSR maintains the HRWG Web site, which provides information on HRWG news, meetings, membership, and publications.

International Archive of Education Data (IAED)

IAED is a project formerly sponsored by the National Center for Education Statistics. The education data stored in this archive are intended to support a wide variety of comparative and longitudinal research through the preservation and sharing of data resources. The archive seeks to serve the needs of academics, policymakers, and researchers in the field of education.

Mexican American Trajectories: Family, Geography, and Intermarriage Across a Century

This website examines family and household relationships of Mexican origin Americans between 1880 and 1990. The research contrasts Mexican Americans to a variety of other immigrant origin groups (the Irish, Italians, Poles, Chinese, and Puerto Ricans) and to blacks and native whites. It assesses the effects of ethnicity on family structure, and especially on the household circumstances of children.

Minority Data Resource Center (MDRC)

MDRC is a membership-funded archive whose purpose is to provide data resources for the comparative analysis of issues affecting racial and ethnic minority populations in the United States. We offer streamlined access to existing ICPSR data and to newly acquired studies that are relevant to the study of immigration, place of origin, ancestry, ethnicity, and race in the United States. Access to MDRC data is available to anyone at an ICPSR member university or institution.

National Archive of Computerized Data on Aging (NACDA)

NACDA is funded by the National Institute on Aging. NACDA's mission is to advance research on aging by helping researchers to profit from the under-exploited potential of a broad range of datasets. NACDA acquires and preserves data relevant to gerontological research, processing as needed to promote effective research use, disseminates them to researchers, and facilitates their use.

National Archive of Criminal Justice Data (NACJD)

NACJD was established in 1978 under the auspices of ICPSR and the Bureau of Justice Statistics, U.S. Department of Justice, and currently also receives funding from the National Institute of Justice, U.S. Department of Justice. At present, NACJD holds over 700 data collections relating to criminal justice. NACJD facilitates and encourages criminal justice research through the preservation and sharing of data resources, and through the provision of training in quantitative analysis of crime and justice data.

Population and Environment in the U.S. Great Plains

This project is a study of the reciprocal relationship between population and environment in the American Great Plains focusing on the relationship between the agricultural land-use and demographic behavior. The researchers have collected county-level data on agriculture, population, and the biophysical environment from between 1870 and the present (for roughly 450 counties), and collaborated on local small-scale studies. Funded by the National Institute for Child Health and Human Development, the project's county dataset is now based at the University of Michigan, where the principal investigator serves as ICPSR director, and a web-based extraction system will be made publicly available.

PreK-3rd Data Resource Center: The First Six Years of Schooling and Beyond

The PreK-3rd Data Resource Center is an online resource center designed to expand the knowledge base and provide tools for the access and handling of Prekindergarten through Third Grade longitudinal data. The goal of this project is to inform the Foundation for Child Development's PreK-3rd initiative and build the research field by facilitating the analysis of rich, complex, longitudinal datasets that contain a wide range of variables on the child, family, school, and neighborhood. The Web site disseminates datasets and user guides developed to provide researchers with detailed guidance in creating their own extract datasets.

Substance Abuse & Mental Health Data Archive (SAMHDA)

SAMHDA is an initiative of the Office of Applied Studies at the Substance Abuse and Mental Health Services Administration of the United States Department of Health and Human Services. The goal of the archive is to provide ready access to substance abuse and mental health research data and to promote the sharing of these data among researchers, academics, policymakers, service providers, and others.

Terrorism & Preparedness Data Resource Center (TPDRC)

TPDRC archives and distributes data collected by government agencies, non-governmental organizations, and researchers about the nature of intra- (domestic) and international terrorism incidents, organizations, perpetrators, and victims; governmental and nongovernmental responses to terror and citizen's attitudes towards terrorism, terror incidents, and the response to terror.
