Take out the “presumed”, and what would the statistics show?
Who knows? Not that I truly understand the question.
To my mind, it remains an apples-to-apples comparison, since the "deaths involving COVID" designation is that which is put on individual death certificates by doctors, hospitals, and other individual health care entities throughout the country and then reported as such to the NCHS. However those myriad designations were being made in September 2020, they were still being made in September 2021.
Given this, the question remains: why are there more deaths involving COVID now, when millions of people in the U.S. have been vaccinated, compared to this same time a year ago, when no one had been vaccinated? Many more deaths, to my eye. I don't myself know the answer to that question, but I think it fair to pose it.
