Welcome to the

Understanding America Study

The Understanding America Study (UAS) is a panel at the University of Southern California (USC) of approximately 6,000 households representing the entire United States. The study is an ‘Internet Panel,’ which means that respondents answer our surveys on a computer, tablet, or smart phone, wherever they are and whenever they wish to participate.

Surveys are designed by research teams around the world; programmed and tested by our team at the Center for Economic and Social Research, translated into Spanish and then fielded.

A majority of the UAS data is publicly available. An excellent start is the UAS Comprehensive File, which merges the data from a number core surveys in the UAS that are repeated every two years.
