All Northwestern faculty, students and staff have access to the services and data provided by ICPSR through its web server. Note that access to the data warehoused in ICPSR requires knowledge of a statistical or programming language, as most of the files are flat ASCII files.

The institutional subscription is managed by Northwestern Library's Social Sciences Data Services. Please check their web site for additional documentation on ICPSR and other institutional memberships.


ICPSR is the world's largest data repository. The data holdings cover a broad range of disciplines, including political science, sociology, demography, economics, history, education, gerontology, criminal justice, public health, foreign policy, and law. ICPSR's web site allows searching the archive and downloading of data and codebooks. The latter (if the dataset is the result of a survey) frequently include the questionnaire or survey instrument.

In addition to being a data repository, ICPSR offers training opportunities by means of its Summer Program in Quantitative Methods of Social Research. Since Northwestern University is a member of the Committee on Institutional Cooperation (CIC), students get a significant discount in tuition (students remain registered at Northwestern and pay only the regular fees charged while in residence at Northwestern).
