Why this data matters
This project was launched out of The Atlantic to fill a major gap in publicly available COVID-19 testing data. Johns Hopkins University maintains a comprehensive case count, but no governmental or institutional source is publishing complete testing data—including not just identified cases, but how many people have been tested, and where. Without this data, we can’t make informed decisions or accurately communicate risks. More >>
Check your state's testing data report card to see the quality of the data they are providing.
