The menu at the top of this page provides links to documents and data from the Understanding America Study's Understanding Coronavirus in America (“Covid”) survey of attitudes and behaviors around the Novel Coronavirus pandemic in the United States. The project was launched with a stand-alone survey on March 10, 2021 (wave 1). The tracking survey (waves 2-29) included a national long-form questionnaire and a Los Angeles County short-form questionnaire and ran from April 1, 2020 through July 2021 . Tracking survey waves 2-24 were administered bi-weekly (national) and weekly (LA County) from April 1 2020 through February 16 2021. Survey waves 25-29 were administered monthly (national) and bi-weekly (LA County)from February 17-July 20, 2021. Subsequent waves are conducted as stand-alone surveys.

A comparison of the UAS Covid-19 data with several other Covid-19 survey data sources is available in the UAS Covid-19 Comparison With Other Data Sources.

Reports, questionnaires, toplines, single data files, a longitudinal data file, and documentation are provided after the end of each wave of the UAS COVID survey. The data may be accessed via the Data tab in the menu above (or directly here for National Survey Data and Los Angeles Survey Data data). Details on how to access Covid survey microdata are also found on the Data tab. Reports, questionnaires, toplines and other documentation are located in the Documentation tab. Press releases, graphics, and other reports are provided via the Press tab. Browse publications associated with this data collection on the Publications tab.
