Weekly Update: Which COUNTIES have the highest per capita rates of #COVID19 cases and deaths?

The data below comes from the GitHub data repositories of Johns Hopkins University, except for Rhode Island, Utah and Wyoming, which come from the GitHub data of the New York Times due to the JHU data being incomplete for these three states. Some data comes directly from state health department websites.

Note that a few weeks ago I finally went through and separated out swing districts. I'm defining these as any county which where the difference between Donald Trump and Hillary Clinton was less than 6 percentage points either way in 2016. There's a total of 198 Swing Counties using this criteria (out of over 3,200 total), containing around 38.5 million Americans out of over 330 million nationally, or roughly 11.6% of the U.S. population.

With these updates in mind, here's the top 100 counties ranked by per capita COVID-19 cases as of Saturday, October 10th (click image for high-res version). Blue = Hillary Clinton won by more than 6 points; Orange = Donald Trump won by more than 6 points; Yellow = Swing District

Lincoln County, Arkansas, now holds the #1 spot. Over 2,200 of their 13,000 residents have now tested positive for #COVID19.

14 of the top 20 counties were solidly won by Donald Trump in 2016, as were 68 of the top 100.

The first New York county, Rockland (a swing county), comes in at #141.

New York City's 5 boroughs, however, continue to drop on the list:

  • #458 (Bronx)
  • #590 (Staten Island)
  • #673 (Queens)
  • #941 (Brooklyn)
  • #1,507 (Manhattan)

Michigan's first listing is deep red Iron County (#843). Wayne County is down at #1,478. Oakland County, where I live, is #1,791.

Here's the top 100 counties ranked by per capita COVID-19 fatalities as of Saturday, October 10th (click image for high-res version):

Of the top 100 counties:

  • 23 are in Georgia
  • 14 are in Mississippi
  • 14 are in Texas
  • 7 are in Louisiana

New York City's 5 boroughs now rank #12, 18, 25, 52 and 94. Wayne County, Michigan (which includes Detroit) is now down to #138.

It's also worth noting how the ratio of per capita cases has shifted between the Clinton and Trump counties over time. Back in mid-March, the rate was 450% higher in Clinton-voting counties than Trump counties. As of this weekend that ratio was down to 9% higher. In terms of the mortality rate, the ratio has dropped from 530% to 171% higher.

As you can see below, separating out the ~200 swing counties from the Red and Blue ones caused the ratio between the two for both case rates and death rates to bump back up towards a higher blue county rate, but only slightly and only for that one week. The trend has continued downwards since then:

I've also taken a look at the counties with the lowest rates of COVID-19 cases and fatalities:

  • There are 400 counties nationwide which have no COVID-19 deaths as of yet, down from 445 a week ago.
  • There are only 5 counties nationwide which don't have any cases yet:
    • Hoonah-Angoon Census Area, Alaska
    • Lake & Peninsula Borough, Alaska
    • Kalawao County, Hawaiii
    • Esmeralda County, Nevada
    • Loving County, Texas

Total population of these 10 counties? 4,868 people.
