In the age group from 45 to 49 in the USA, mortality was set back by 40 years in 2021:
The death rate for those of age 45 to 49 in 2021 reached a level that had not been seen in that age group for 40 years, all the way back to 1981. Because COVID shots rolled out by 2021, they are the most-likely cause.
The 2021 death rate was 39% higher than the mean of the 2015-2019 death rate, and using the standard deviation from 2015-2019, the 2021 death rate was 48 standard deviations above the mean.

Great numbers, great work. You live and learn although I do miss ignorance, those were the days!
