The Understanding America Study (UAS) is a panel at the University of Southern California (USC) of approximately 6,000 individuals 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.
The majority of the panel members have their own Internet access. The remaining panel members have been provided Internet access by USC through the provision of a tablet and/or an Internet subscription. At this time the UAS only asks surveys of adults aged 18 and over. It is not possible to volunteer for joining the UAS. We randomly select people around the country using postal codes.
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.
Final datasets for finished surveys are posted on our site with sample weights.
Note to registered users: We have recently updated our data user agreement. In light of this change we have contacted you with details on how to restore access. You can also download the new data user agreement here, complete and sign it, and return it as indicated on the form.
