Here's what I did. I took the 20 most populated cities in the country (or rather, the counties containing those cities) and looked at both daily Covid rates (over the past 14 days) and full vaccination rates. What I was curious about was whether there was any correlation between the rapid spread of Omicron and vaccination rates. Here are my findings:
Vaccination rates ranged from a low of 52% in the county containing Indianapolis to a high of 81% in the county containing San Jose. Daily case rates (per 100k of population) ranged from a low of 23 in the county containing Fort Worth to a high of 293 in Washington DC.
The correlation graph goes from a low of 24 cases at the lowest vaccinated part of the graph to a high of 70 cases at the highest vaccinated part. Translation: Covid is spreading 2.9x faster in the highest vaccinated regions than in the lowest. This fairly closely mirrors the national average of 3.5x faster when sorting by state.
Perhaps most fascinating is that each and every one of the 6 LEAST vaccinated areas (counties containing Indianapolis, Phoenix, Fort Worth, Dallas, San Diego, and Jacksonville) had daily case rates below the median of 78. Only 1 of the 10 least vaccinated areas (Columbus) had a daily case rate over 100 while half (5 out of 10) of the most vaccinated areas (Philly, DC, Chicago, Denver, and New York City) had rates over 100.
I'll post the raw data and some graphs later, and if I have extra time, I may expand this list out to the top 30 or 40 most populated cities, but bottom line appears to be that Omicron is literally spreading 3x faster in the highest vaccinated big cities than it is in the lowest vaccinated big cities.
EDIT - Here is the raw data thus far. I'll post more when I have more time later.
