Core Partners

Among ICPSR Thematic Collections is a small core of long-term archiving projects that represent sustained commitment and support by the project sponsors. These sponsors have worked with ICPSR over many years to enhance and preserve substantial data collections, build improved tools for online data analysis, and increase the research tools available to users.

Child Care and Early Education Research Connections

Research Connections (RC) offers a comprehensive, easily searchable collection of more than 15,000 resources from the many disciplines related to child care and early education. The site offers the most current publications, as well as links to child care policy statements.

Data Sharing for Demographic Research (DSDR)

DSDR provides resources to demographic data producers and users, including confidentiality and disclosure review, restricted data contract development and data dissemination, a searchable index of important demography and population study data, and a catalogue of publications using data indexed.

Health and Medical Care Archive (HMCA)

HMCA preserves and disseminates data collected by research projects funded by The Robert Wood Johnson Foundation, the nation's largest philanthropy devoted exclusively to improving the health and health care of all Americans.

National Archive of Computerized Data on Aging (NACDA)

NACDA acquires and provides access to data relevant to gerontological research with an emphasis on major issues of scientific and policy relevance.

National Archive of Criminal Justice Data (NACJD)

NACJD facilitates research in criminal justice and criminology through the preservation, enhancement, and sharing of computerized data resources. NACJD also promotes original research based on archived data and provides specialized training workshops in quantitative analysis of crime and justice data.

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.

Substance Abuse and Mental Health Data Archive (SAMHDA)

SAMHDA provides public data access and online analysis for important substance abuse and mental health data collections. The project offers variable-level searching, an archive of survey instruments, related literature for data collections, a listserv, disclosure analysis, and traditional data products. SAMHDA was established at ICPSR in 1995 by the Office of Applied Studies (OAS), Substance Abuse and Mental Health Services Administration (SAMHSA).
