Who We Are

The Roper Center for Public Opinion Research is the largest archive of public opinion data in existence. The Center holds data dating back to the 1930’s and from over 60 nations.

The Roper Center is a public opinion archive — it preserves the data from polls conducted by many leading survey organizations for the use of researchers, students, and journalists. Read more about the purpose of the Center.
Elmo Roper founded the Roper Center just after World War II. He and George Gallup played leading roles in its subsequent development. The survey organizations they established have continued to contribute their polls to the Center’s library, and scores of other survey organizations in the United States, and many foreign countries, have followed their example.
