The Roper Center for Public Opinion Research, currently located at Cornell University, is one of the world’s leading archives of social science data, specializing in data from public opinion surveys. The Center’s mission is to collect, preserve, and disseminate public opinion data; to serve as a resource to help improve the practice of survey research; and to broaden the understanding of public opinion through the use of survey data in the United States and abroad. Founded in 1947, the Roper Center holds polling data ranging from the 1930s, when survey research was in its infancy, to the present. Over 650,000 questions of U.S. samples can be searched at the question-level in iPOLL, while RoperExpress offers downloads of over 20,000 datasets from over 100 countries.
