The Inter-university Consortium for Political and Social Research (ICPSR), the world's largest repository of digital social science data, provides leadership and training in data access, curation, and methods of analysis for a diverse and expanding social science research community.

The ICPSR repository spans the behavioral and social sciences and includes data on sociology, political science, demography, economics, history, criminal justice, gerontology, public health, education, criminal justice, gerontology, substance abuse, international relations, and much more. ICPSR's Summer Program in Quantitative Methods is internationally recognized as the premier program for training in the methodology of social science research.

ICPSR's membership includes over 650 educational and research institutions around the world. ICPSR member institutions pay annual dues that entitle faculty, staff, and students to the full range of data resources and services provided by ICPSR, but many of the ICPSR data holdings are freely available to anyone.

ICPSR content takes the form of numeric data files and associated PDF technical documentation (over 500,000 discrete files comprising over 7000 studies) that may be analyzed using statistical software packages or, in some cases, online analysis software. Each study in the holdings has a corresponding descriptive metadata record.

Data in the repository are linked to related publications in the research literature via a Bibliography of over 45,000 entries. Similarly, citations in the Bibliography are linked to the data that generated the research findings. Full text is available for many publications in the Bibliography. ICPSR content provides a rich resource for data mining.
