Roper Center for Public Opinion Research

Dates Covered & Contents:

The Roper Center for Public Opinion Research, located at Cornell University, is one of the world’s leading archives of social science data, specializing in data from public opinion surveys. Includes the iPoll question databank, a vast collection of surveys from Gallup, Harris, Roper, the New York Times, and many other organizations covering national public opinion. iPoll searches at the question-level, allowing you to sift through more than half a million questions asked since 1935. See also their topical collections for pre-made tables, graphs, and searches. Roper also provides access to more than 10,000 international surveys. You can search by keyword, by topic, by country, or by organization. Datasets for most studies (those with an X icon) can be downloaded after you register; studies with a green and blue star icon can be analyzed online.
