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


Washington state

There is a growth in counted cases nation-wide. Taking these number at face value, I would point out that the rate of growth exceeds that of the July and April in slope.

King county trends above the state average for the first time since May

For the first time in six months, King county is just above the state average with a trailing average of 16.8. This change started in the beginning of November with a jump in cases.

All counties ranked by trailing average case per 100k as of 11/7/2020

Here is a ranked list of all counties as of 11/7/2020. I have added the nation and Washington State as a whole to help contextualize the numbers. Garfield is at the top of this list, but only due to the small population of around two thousand.

Table of all trailing averages for Washington counties for 11/7/2020. Walla wall, Adams, and Asotin county exceed the USA average. Counties that exceed the state average are Benton, Franklin, Chelan, Spokane, Grant, Douglas, Whitman, Pierce, Columbia, Stevens, and King.

Walla walla’s case count has been higher than the US average and trends upward

In my prior analysis, Walla walla county showed a sharp increase in new COVID-19 cases. This trend has continued without any downturn. Since 10/22/2020, Walla walla county’s count of new cases has surpassed even the US average. A visual inspection of the past 14 days shows a consistently growing margin between the US average and the county.

Adams and Asotin county have also exceeded the national average

Adams and Asotin county

Benton has hit the national average

Benton county has had an aggressive slope since the start of November and has now hit the national average.

Spokane county (523k) has remained above average for 2 months

Looking into the past, Spokane county stands out with a steady position above the state average for 2 months.

Whitman county shows recovery to the norm

Whitman county has managed to bring down its new cases count dramatically. In the past two weeks it dropped from an average of 32 cases per day down to 14. Although there is a small uptick in the past few days.


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.
