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

COVID-19 Vaccine

Methodology reminders:

  • I go by county residents who have received the 2nd COVID-19 shot only (or 1st in the case of the J&J vaccine). Data for 3rd/booster shots aren't available at the county level in most states yet.
  • I base my percentages on the total population, as opposed to adults only or those over 11 years old (or even over 4 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 December 13th, 2021:

It's also important to note that both the R2 (correlation) and slope formulas, which had plateaued for most of October and November, appear to be increasing again now that the first batch of 5 - 11 year olds have started receiving their 2nd Pfizer shot:

Here's what the data above looks like in bar graph format, broken out in rough deciles (tenths of the total population, or around 33.1 million people apiece). The vaccination rate in the bluest tenth of the nation is running 63% higher than the reddest tenth:
