Thematic Collections

Over the years, ICPSR has collaborated with a number of funders, including U.S. statistical agencies and foundations, to create archives organized around specific topics. These Thematic Collections and the new services created for them bring a dynamism to ICPSR from which the broader social science research community benefits. The funders provide new data, in most cases free to everyone, and this stimulates more research. The funded archives and ICPSR collaborate to build additional infrastructure for effective data use and discovery.

The AHRQ MCC Research Network works to advance the field of Multiple Chronic Conditions (MCC) research, provide needed guidance for clinicians and patients, and advise policy makers about improved methods to measure and promote quality care for complex patients. This website is dedicated to disseminating data and other documentation created by the AHRQ MCC Research Network.

NAHDAP acquires, preserves and disseminates data relevant to drug addiction and HIV research. By preserving and making available an easily accessible library of electronic data on drug addiction and HIV infection in the United States, NAHDAP offers scholars the opportunity to conduct secondary analysis on major issues of social and behavioral sciences and public policy. NAHDAP was established at ICPSR in 2010 by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.

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