The Inter-University Consortium for Political and Social Research (ICPSR) is an organization of member institutions that support the acquisition and preservation of social science data, to provide open and equitable access, and to promote effective data use, by: 

• maximizing access to research data for analysis and publications
• providing data management & curation services to fulfill grant requirements and assure long-term viability of research data
• educating and training current & future research methodologists & data scientists 

ICPSR is the world's largest archive of computer-readable social science data including education, public health, sociology, political science, criminal justice, history, and economics, and contains thematic data archives such as Aging and Health, Child Care and Education, and Criminology and Criminal Justice

While the ICPSR holdings include several time series and other types of aggregate data, the holdings consist mainly of raw data derived from surveys, censuses, and administrative records. 

ICPSR sponsors summer courses and workshops on such topics as "Quantitative Research on Race and Ethnicity," "Longitudinal Analysis of Historical Demographic Data" and much more. For more information about ICPSR programs, see the ICPSR Web Site.
