The COVID Tracking Project

Our data compilation is finished. Our research and analysis work continues through May.

Our final data collection shift took place on March 7, 2021. Don’t worry, all our data is still here.

We would like to thank the hundreds of volunteers who,
for the last 12 months, collected and published

the most complete data about COVID-19 in the US.
