Weekly Update: County-level #COVID19 vaccination levels by 2020 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).
  • Note: I've temporarily stopped tracking boosters again, as it appears that the data on this front is still too confused to get an accurate county-level national read.

• 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 and West Virginia, I'm using data from the COVID Act Now Risk & Vaccine Tracker database
  • For Virginia, I've (reluctantly) switched back to using COVID Act Now data even though it's had some strange data lately. I'd normally use the official state health department dashboard, but theirs doesn't allow you to export, view or download all 95 counties/city-counties at once, making this a tedious effort.

• • 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.

• 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).

• BY POPULAR REQUEST, here's an updated Google Spreadsheet with all the relevant data.

• 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 7th, 2022:

As I predicted back in mid-November, the most obvious reason for both the R-squared and slope increasing again recently 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:

• There's 12 Counties where over 90% of their populations have received their 2nd shot, with ~428,000 residents, including:
  • Bristol Bay, AK (pop. 844)
  • Apache County, AZ (pop. 66,021)
  • Santa Cruz County, AZ (pop. 47,669)
    • (Note: there's a serious discrepancy between the official CDC vaxx rate & the AZ Health Dept. for both Apache & Santa Cruz)
