State-level Metrics
New tests Total PCR tests (specimens)
New cases (Notes)
Current hospitalizations
New deaths
- Nov 6: On November 6, 2020, Illinois announced that they “will report confirmed cases and probable cases combined” going forward rather than reporting them separately. The time series for the Confirmed and Probable Case metrics are available in the historical data, and our data downloads.
We calculate daily changes based on the data states report each day. Some states report new cases, tests, and deaths using other methods. Please consult official state data sources for more information. We chart “New tests” using different units across jurisdictions, because not all states and territories report tests in the same units. Learn more about total test units and see what we chart for each jurisdiction in our total tests documentation.
We do not have a complete dataset for every metric in every state. If we have data for less than 30% of the past 90 days for a given metric, you’ll see a warning instead of a chart for that metric.
All the data for these charts is available for download. You can also review tabular national data on our US historical data page and data for each state and territory on the individual state or territory’s overview page.

Race & ethnicity data
We compute the number of cases and deaths per 100k people for each race and ethnicity.
These numbers show the scale of outcomes compared to the size of each group’s population. These are not the number of cases or deaths, rather the proportion of each demographic group who have been affected.
Race & ethnicity: cases per capita

The changes in ME dropped totalTestResults by around 40k. The changes in IL made no impact to the value of totalTestResults at the topline but may have shifted earlier values.
