The Roper Center for Public Opinion Research is one of the world's leading archives of social science data, specializing in data from surveys of public opinion. The data held by the Roper Center range from the 1930s, when survey research was in its infancy, to the present. Most of the data are from the United States, but over 50 nations are represented.
Our membership with the Roper Center is now active and ready for use. With the membership, University of Minnesota current students, faculty and staff have access on and off campus to the full suite of Roper content, including iPoll and the Dataset Collection.
For surveys with national adult or major subpopulation samples (such as registered voters, women, or African Americans), iPOLL can be used as the primary finding aid to locate datasets on particular topics or for specific time periods. For state, foreign, and other special samples, the Dataset Collections can be used to locate datasets by keyword (the abstract is searched), date, country, survey organization, survey sponsor, or type of sample. Our membership includes downloads of all files in the Roper Express collection.
Roper also offers the option to do online analysis of selected datasets through the IDEAS: Interactive Data Exploration & Analysis System.
