King County

Until early May, King County was the leader in average COVID-19 cases per 100k citizen for the state of Washington. The King County curve sloped down below the state average only to aggressively turn upwards, peaking on July 4th, both to hit the state average and then to decline sharply. Since then, King County has held a comfortable below-average position to date.


Since almost the start, Seattle has maintained a comfortable below-average position against the county with one exception. Like King County, there was an aggressive upward slope at the end of June. This culminated into a record number of cases in early July. Seattle then dropped down to below-average again to resume a below-average position to date.

Auburn, Bryn Mawr-Skyway, Burien, Covington, Federal Way, Kent, Lakeland North, SeaTac, and Tukwila are trending high

By a rough visual review, I would point out these cities as having an above-average trendline for the past few days. Historically, I would note that some of these cities have always maintained an above-average position. Those are Auburn, Federal Way, Kent, SeaTac, Tukwila.

Snoqualmie, White Center, North Bend, Woodinville, Lake Morton-Berrydale, Fairwood, and Bothell show success in responding to a recent peak above average

These cities experienced a sharp peak above average, then their number have dropped to or below average in a promising fashion.


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.
