New cases per 100,000 residents (14-day average)



Westchester County does not currently publish historical data at the municipal-level, but I have reconstructed this data using maps posted on the WestchesterGov Twitter account. The earliest maps that included the number of active cases by municipality were posted in early May. As such, the data I have largely misses the first wave of the pandemic from March and April 2020.

The chart below shows the severity of the pandemic in each municipality by plotting the rolling 14-day average of new cases per 100,000 residents by day. The municipalities are ordered from top to bottom by their current average daily cases per 100,000.
