ICPSR is the world's largest collection of digital social science data - www.icpsr.umich.edu. 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.
OACS pays the annual membership fee to ICPSR for data access so that BSOS faculty, staff, and students can eaily access data for BSOS-centered research. Data can be downloaded directly from ICPSR to BSOS office desktop computers. If downloading to a BSOS desktop is not an option, please contact Marie Gates-Liden in OACS for assistance.
