Getting Polling Data from the Roper Center for Public Opinion

If you are looking for polling or public opinion data, you should check the archives of the Roper Center for Public Opinion Research. The Roper Center maintains "the most comprehensive and up-to-date source of national public opinion in the United States." Stanford University is a member of the Roper Center, so the data in the Roper archive, as well as other resources can be accessed by you. Search the Roper Center Catalog of Holdings to locate polling data in their collection.  Datasets can be searched by keyword, date range, survey organization or sponsor, and the sample type.

Contact us for data help if you need assistance using the Roper web site.  If you cannot find the data that you need at Roper, then check out other selections under Data Resources.

 iPOLL Databank and iPOLL Plus

A large number of Roper Archive datasets can be located using Roper's iPOLL, a searchable database of polling questions and their responses that link questions to their catalog of data holdings.   Any computer on Stanford's central campus network can access the iPoll database directly.  You will need to register with your email address to access iPoll.

iPOLL Plus provides demographic crosstabs alongside the iPOLL questions.  Currently iPoll survey questions from around 1995 onward have been processed for iPoll Plus.  An iPOLL Plus icon identifies questions that include demographic banners.  Access the iPOLL Plus video tutorial to learn more about this feature. 

Roper Express and Roper Explorer

Roper Center datasets with directly downloadable SPSS or ASCII data files are available via Roper Express.  These datasets are marked with the RoperExpress 'X' icon. 

A number of Roper datasets are available for online analysis via their RoperExplorer system.  Check out the RoperExplorer "how to" guide  and video tutorial

Other Center Polling Collections

The Roper Center is the repository for some international archives of polling data. One example is the Latin American Databank (LAD), which currently has almost one thousand studies from 16 countries, including Argentina, Chile, Mexico, Peru and Venezuela.  Links to this  and other collections are on the Roper Center web site.
