Weekly Update: County-level #COVID19 vaccination levels by 2020 Partisan Lean

COVID-19 Vaccine

NOTE: Given how much the national pace of vaccination shots has slowed down recently (the 7-day average is down to around ~330,000/day), going forward this will be a MONTHLY update, unless the pace picks up again significantly.

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).
  • I base my percentages on the total population via the 2020 U.S. Census 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.
  • There are several counties which have supposedly surpassed 100% vaccination rates; obviously that's impossible, and is due to discrepancies in either the vaccination data or actual population counts. In addition, people have moved, died, etc. since the 2020 Census was locked in as of April 2020. With that in mind, I've started setting the maximum vaccination rate for any county at 98%.

With all this in mind, here's what things looked like as of February 27th, 2022:

It looks like the mini-spike of the R-squared line increasing in response to 5-11 yr olds receiving their 2nd COVID shots starting around Thanksgiving has leveled off again, although the slope line is still getting steeper. I'd imagine there will be one more final mini-spike once children under 5 years old are approved to get vaccinated as well; after that there's really no way for the slope to increase any further as the bluest counties are starting to bump up against their likely vaccination rate ceilings.
