SDA is a set of programs for the documentation and Web-based analysis of survey data. SDA was developed, distributed and supported by the Computer-assisted Survey Methods Program (CSM) at the University of California, Berkeley until the end of 2014. Beginning in 2015, CSM is managed and supported by the Institute for Scientific Analysis, a private, non-profit organization, under an exclusive continuing license agreement with the University of California. CSM also develops the CASES software package.

To see how it all works, test-drive SDA at our demonstration SDA Archive. Browse the documentation for a survey and get fast data analysis results. The SDA Archive includes several datasets, including the General Social Survey (GSS), the American National Election Study (ANES), and the Survey of Consumer Finances (SCF). You can also look at some other archives that use SDA software.

For information on obtaining SDA software and services, see the SDA Software and Services page.
