Monthly Update: County-level #COVID19 vaccination levels by 2020 Partisan Lean (w/Miami-Dade correction)

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), this is now 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).

• 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

• • For California, Colorado, Georgia, Hawaii, Minnesota and Texas, I'm using their COVID vaccine dashboards set up by the state health departments.
  • For Massachusetts, I use CDC data for most counties but 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 March 26th, 2022:

The most notable change in this update is Miami Dade County (located at around 46% Trump / 72% vaccinated), which until now was listed as being more like 85% vaccinated.

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. 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:
