COVID in Washington State, county-level (9/11/2021)
Here are charts for Washington State counties. These charts rely on the New York Times’ published data on COVID-19 in the United States. I am primarily use their county-level data set together with population estimates (Wikipedia reports on US Census data from 2019).
I have produced charts of new cases of COVID-19 as
- 7-day trailing averages
- scaled to cases per 100k.

All of my charts and tables are shared in a public Google sheets document:
Washington State is not much lower than the national average
The entire state has a 14-day trailing average of 42.03 cases per 100k. The country equals this at 44.72 cases.
King County’s average is a flat line in the past month, a clear deviation from the national and state-wide peak
King County appeared to cut off its rate of increase in cases about a month ago. It has held steady between 22 and 29 new cases on average. In recent days, there is a possibility of drop.
All counties ranked by trailing average case per 100k as of 9/11/2021
Here is a ranked list of all counties as of 9/11/2021. I have added the nation and Washington State as a whole to help contextualize the numbers.
More than 20 counties in the state are positioned above the state average.
Here are graphs for the top five counties in the state
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.
