I was puzzled by the CDC’s recent claim that the Wuhan Virus Pandemic had cased a one year drop in life expectance in the U. S. It turns out that their claim is so screwed up it isn’t even wrong. If life expectancy has dropped because of Covid, the decline is probably less than a week, an amount so small that it’s inside the roundoff error of the statistics. Eugene Volokh has a post up with details from a report by Dr. Peter Bach.
Analysts estimate that, on average, a death from Covid-19 robs its victim of around 12 years of life. Approximately 400,000 Americans died Covid-19 in 2020, meaning about 4.8 million years of life collectively vanished. Spread that ghastly number across the U.S. population of 330 million and it comes out to 0.014 years of life lost per person. That’s 5.3 days. There were other excess deaths in 2020, so maybe the answer is seven days lost per person.
No matter how you look at it, the result is a far cry from what the CDC announced.
It’s not that the agency made a math mistake. I checked the calculations myself, and even went over them with one of the CDC analysts. The error was more problematic in my view: The CDC relied on an assumption it had to know was wrong….
Apparently, 2 + 2 equals whatever the public health establishment needs it to be.
