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 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: There's several counties in Virginia where I'm using the official state health department dashboard instead this week specifically due to some weirdness in the COVID Act Now data. If these issues continue I may have to switch to the state dashboard for all counties for VA going forward, which would be a royal pain given the inability to export every county at once.

• • 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.

With all this in mind, here's what things looked like as of January 5th, 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:

Other things especially worth noting:

• Kalawao County, HI (pop. 82) is still the only one which is 100% vaccinated.

• 9 Counties with over 90% of their populations having received their 2nd shot have ~166,000 residents, including the above plus:
  • 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 of these counties)
  • Dukes County, MA (pop. 20,600)
  • Nantucket County, MA (pop. 14,255)
  • Hudspeth County, TX (pop. 2,912)
  • Presidio County, TX (pop. 6,131)
  • Charles City, VA (pop. 6,773) (maybe...see note above re. Virginia data)

• 30 Counties with over 80% of their total populations having received their 2nd shot have ~7.78 million residents, including the above plus:
  • Haines County, AK (pop. 2080)
