COVID in King County, charts per city (3/29/2021)

Here are charts for King County cities. These charts rely on the King County outbreak summary dashboard together with population estimates from the JC_Rook’s daily spreadsheet report on King County.

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:

King County

King County is seeing a rise in new cases that matches the state average.


Seattle shows a similar uptick in cases from about a week before, though it remains below the overall average of King County itself.

King County cities ranked as of 3/29/2020

  • Only cities with population > 5k
  • All of USA, WA and King County are included as reference points.

Charts for top 5 cities

Auburn, Enumclaw, Maple Valley, Hobart, Pacific all supercede the average for the entire USA by at least 10 cases per 100k.


I chose these the average and 100k transformations to help readers identify how COVID-19 is trending in each chart and to allow readers to make fairly direct comparisons city-to-city.

These charts compare each city against the entire county. This allows us to say whether or not a city has generally been doing better or worse than the rest of the county. I am using the trailing averages and trend line comparison to mitigate the way that testing patterns have changed since the early months.

I generally refrain 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.
