COVID-19 testing statistics in California

All measures below are rolling 7 day averages except Total Tests and Total Tests per 1M residents which are cumulative counts of COVID-19 tests as of the date reported. Testing statistics are dependent on high quality reporting of negative test results by states. Not all states report all tests and thus some of these measures may not represent the true testing picture.

A final word on this analysis

Please take my calculations and amatuer epidemiological speculations with a grain of salt as I'm moving quickly to get what I hope are meaningful measures online. There may be errors in my data and my thinking! Also, this data may be revised as states revise and backfill their data.

These statistics were inspired by posts on Calculated Risk and the Bondad Blog regarding metrics to track for COVID-19.

Last but not least, thanks to the folks at COVID Tracking Project for making this data available to everyone.
