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 via the 2020 U.S. Census as opposed to adults only or those over 11 years old (or even over 4 years old).
  • For most states + DC I use the daily data from the Centers for Disease Control, but there are some where the CDC is either missing county-level data entirely or where the CDC data is less than 90% complete at the county level. Therefore:
    • For Vermont, Virginia and West Virginia, I'm using data from the COVID Act Now Risk & Vaccine Tracker database
      • NOTE: I've started using the official state health department dashboard for Virginia this week due to some weirdness in the COVID Act Now data. Unfortunately¬†the VA Health Dept. dashboard doesn't allow you to export, view or download all 95 counties/city-counties at once, making this a tedious effort, so I'm not sure how I'll deal with it going forward.
  • 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.
  • IMPORTANT: There are now 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 one exception: Kalawao County, Hawaii, which only has 82 residents & is a special case.

With all this in mind, here's what things looked like as of January 16th, 2022:

The most noteworthy thing this week is that the R-squared for this graph has now moved over the 0.5 threshold, and the slope angle has started to increase again as well.

As I predicted back in mid-November, the most obvious reason for this is that 5 - 11 year-olds started receiving their 2nd Pfizer shot around Thanksgiving. The parents who were most likely to have gotten vaccinated themselves earlier this year are pretty clearly the ones most likely to get their children vaccinated, and the parents least likely to get vaccinated are, sadly, also those least likely to vaccinate their children either:
