The Roper Center for Public Opinion Research collects, preserves, and disseminates public opinion data. Its collection includes over 22,000 datasets from the 1930s to the present, containing responses from millions of individuals on a wide range of topics, including politics, elections, U.S. policy, and social issues. This database is sponsored by the College of Liberal Arts. For special expertise with the database, contact Dr. Greg Bohr. This database will no longer be available after October 31, 2018.
