The Inter-university Consortium for Political and Social Research (ICPSR) is the world's largest collection of digital social science data. These data can be used for secondary research, instructional activities, and to write articles, papers or theses. ICPSR data cover topics from sociology, political science, economics, demography, education, child care, health care, crime, minority populations, aging, terrorism, substance abuse, mental health, public policy, and international relations.
The College of Behavioral and Social Sciences (BSOS) and the University Libraries have partnered to provide campus-wide access to ICPSR for data access so that faculty, staff, and students can easily access data for coursework and research. The ICPSR membership is available to current Faculty and Students at the University of Maryland (College Park campus only). Data retrieved from ICPSR may be used only for research that is to be performed by and used for the purposes of the University of Maryland. ICPSR data may not be redistributed to others, nor may it be used for the advancement of any institution other than the University of Maryland. Individual datasets may have further restrictions regarding use, sharing, and citation.
Find available data at the ICPSR website. Some studies are freely available, while most studies require membership in ICPSR for access. There are studies that are wholly or partially restricted from viewing and use, generally for security/privacy concerns, and these studies will contain information about those restrictions in the study documentation.
Note that some data sets have additional restrictions on use and access. The user is responsible for performing any procedures required to lift additional restrictions.
