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

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).

• 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 Hawaii, Illinois, Vermont, Virginia and West Virginia, I'm using data from the COVID Act Now Risk & Vaccine Tracker database.
  • For Colorado, Georgia, Minnesota, and Texas, I'm using their COVID vaccine dashboards set up by the state health departments.
  • For California, I'm using the CDC data for most counties and the state health dept. dashboard data for the 8 small counties which the CDC isn't allowed to post data for.
  • For Massachusetts, I'm using the CDC data for most counties but am now using the official Massachusetts Health Dept. weekly data report for Barnstable, Dukes & Nantucket counties, which the CDC only has partial data for.

• 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.

• County populations are based on official 2020 U.S. Census Bureau data

• Alaska's 2020 election results are estimated thanks to an updated analysis by RRH Elections (all other states +DC have been using 2020 county-level election data all along).

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:
