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 survey was launched on March 10, and includes a national bi-weekly long-form questionnaire and a weekly Los Angeles County short-form questionnaire administered in each bi-weekly wave. An overall description of the UAS Covid-19 surveys can be found in the UAS COVID-19 Panel Description. 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, data, and documentation are provided for each wave of the UAS COVID survey as it is completed, every two weeks. 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.

You can add questions to the surveys!

Since a new survey is launched every two weeks, it is possible to add questions. Given the wealth of information available, adding one or two questions on a specific topic may open powerful new opportunities for innovative analysis. We are interested in new ideas, and are accepting proposals for one-minute modules (about two to three simple questions) that may be added at no cost! Submissions are screened by UAS staff to verify that proposals meet the criteria laid out below. Proposals that pass the initial screen are evaluated by an external committee (not involving UAS staff) within two weeks of receipt. The committee recommends to “accept”, “reject”, or “accept conditional on making changes”.
Submit your proposal now.

You may add additional or longer modules to the survey as well, at our discounted tracking survey rate. The pricing schedule is straightforward; we charge $2 per respondent for one minute of question time. Since the sample size is about 7,000, one minute of question time in a two-week survey comes to $14,000. Data from each wave remains under embargo to the public until it is complete, during the full 28-day field period. However, authors who add questions have access to the data during the field period, including weighted preliminary files. Preliminary data is useful for analysis as more than 90% of responses are accumulated in the first 14 days.

By proposing and funding new questions, you are supporting the operation and contribute to science for the common good. Just send an email to Tania Gutsche (
