It's funny because I linked the CDC demographics page in my post, which shows various demographic groups ranging from 19.9% to 34.9% as of today. Based on that I threw out the 30% figure. Yet simultaneously they claim that the total number is 42.5%, which would be mathematically impossible if every subgroup is below that number. Turns out they only have race data for 2/3 of vaccinations, and for some reason didn't normalize for this when reporting race demographic percentages. In any case I've added a correction to my post about this, thank you.
