All of my charts and tables are shared in a public Google sheets document:


Washington State

King County

All counties ranked by trailing average case per 100k as of 9/16/2020

Here is a ranked list of all counties as of 9/16/2020. I have added Washington State as a whole to help contextualize the numbers. Due to its small population, Garfield’s second place ranking is not a concern. It records new cases in single digits.

Whitman County continues to lead Washington State in cases

Whitman remains at the top of the list at 55.60 which is almost 10 times worse than the state average (5.98). It has held this position for almost three full weeks.

Adams County

Adams’ holds a 3rd place position at 32.17. One might ask if this is a numeric anomaly with its smaller population (~20k). It has maintained an average of 6–10 new cases a day for the past two weeks. I’ve provided its chart below.


I chose trailing averages and scaled to population (“per 100k”) to help readers identify how COVID-19 is trending in each chart and to allow readers to make fairly direct comparisons county-to-county.
