The Delphi Group at Carnegie Mellon University and the University of Maryland Social Data Science Center partnered with Facebook to launch the COVID-19 Trends and Impact Survey (CTIS) in April 2020. From vaccine hesitancy and barriers to vaccination to mask use and contacts outside the home, our insights continue to provide a clear and holistic view of the pandemic and the rate at which it’s changing. As of June 25, 2022, CTIS will no longer collect new survey data, but historical data will remain available. Please reference the Global CTIS FAQ and U.S. CTIS FAQ for additional information.

Our academic partners make all of our efforts possible. The University of Maryland and Carnegie Mellon University gather the input on survey instruments that is needed to continually provide scientists, researchers, policymakers, members of the press and the general public with detailed reports on the pandemic so we can provide a global view of where—and how—it’s changing.
