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


Washington State trends downward; diverging from a national rise in November

King County is lower than the state average by about 10 cases/100k and also has a downward trend.

Chelan case counts are notably higher than even the US average — though there may be data inconsistencies

All counties ranked by trailing average case per 100k as of 11/24/2021

Here is a ranked list of all counties as of 11/24/2021. I have added the nation and Washington State as a whole to help contextualize the numbers.

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.
These charts compare each county against the entire state. This allows us to say whether or not a county has generally been doing better or worse than the rest of the state. I am using the trailing averages and trend line comparison to mitigate the way that testing patterns have changed since the early months.
I have refrained from speculation about the reasons for each county’s performance in this post and concentrated on simple language: above vs below average and a month to month comparison.
