Weekly Update: U.S. #COVID19 vaccination levels by COUNTY & Partisan Lean

COVID-19 Vaccine

Methodology reminders:

  • I go by FULLY vaccinated residents only (defined as 2 doses of the Pfizer or Moderna vaccine or one dose of the Johnson & Johnson vaccine).
  • I base my percentages on the total population, as opposed to adults only or those over 11 years old.
  • The 5 major U.S. territories don't vote for President in the general election, preventing me from displaying them in the main graph, but I have them listed down the right side.

With all this in mind, here's what things looked like as of yesterday, August 24, 2021:

It's also important to note that while there was a very slight, one-time drop in both the R2 (correlation) and slope formulas a week or so ago when I switched from 2019 estimated population data to official 2020 U.S. Census data for every county, this drop has since reversed itself and continued its gradual climb higher on both the correlation and slope fronts:

Other things especially worth noting:

  • Kalawao County, HI (pop. 82) is still the only one which is 100% vaccinated.
  • After yet another data source correction, I again have Dukes (pop. 20,600) and Nantucket (pop. 14,255), Masschusetts up in the #2 and 3 spots with 88% & 87% of their total populations vaccinated respectively.
  • Bristol Bay Borough, AK (pop. 844) and Hudspeth County, Texas (pop. 4,886) are the highest-vaccinated solid red counties at 86% and 85% respectively. I'll have to look into what's up with Hudspeth County, since USA Today claims they're only at 67%. Huh.
  • At the opposite end, there's still 2 counties below 10% fully vaccinated: McPherson County, SD (pop. 2,411) and Slope County, ND (pop. 706).
  • Of counties with more than 100,000 residents, the top-vaxxed is Marin County, CA (73.9% vaxxed); Montgomery County, MD (71.9%); and Sumter County, FL (71.6% vaxxed), which has overtaken San Francisco, CA (71.4% vaxxed).

Sumter County is a solid red county...but it's also famously (or infamously?) home to The Villages, the massive retirement community where Trump held rallies last summer.

  • Of counties with more than 100,000 residents, the least-vaxxed are Shelby and Limestone Counties, AL, neither of which has vaccinated more than 26% of their total populations.
  • There are 49 counties with more than 1 million residents. Of those, the highest-vaxxed is Montgomery County, MD (71.9% vaxxed) while the lowest-vaxxed is Wayne County, MI (home of Detroit), which has only vaccinated 42.0% of its population.
