Pew Research Center for The People & The Press

The Pew Research Center for The People and the Press conducts numerous studies of public opinion in the US.  Data, results, and analysis from the center's studies are available in several ways.

Survey Reports are usually available shortly after data are collected, and contain basic  descriptive analysis of survey findings, as well as appendices which publish questionnaires and marginal frequencies.  

More interpretative analysis and commentaries about these data by Pew analysts is also available on this site.  

Users may search a database of survey questions and results of all Pew studies through a database collaboration with the Roper Center for Public Opinion Research. 

The center also provides scholars and researchers with access to its datasets for more detailed analysis through its archive.   Survey data are released six months after the reports are issued and are posted on the web as quickly as possible. Datasets can be analyzed in popular statistical packages. 

Detailed discussions of the survey methods used by these studies are also available in deatailed methodological reports.
