The CDC is attempting to cover up the massive increase in US working age mortality in 2021 versus 2019. There were 707,000 US working age deaths in 2019 and 230,000 more in 2021. 2019 was the last pre-pandemic year and was more or less in line with the mortality trend from 2015-2019. After data normalization, there wasn’t much change in US working age mortality between 2015 and 2019. Then there was about a 15% increase in US working age mortality in 2020, which is a multiple sigma deviation* from the 2015-2019 mortality norm. Then, in 2021, there was an additional 17% increase in US working age mortality, which adds more multiples to the deviation of 2020.
The CDC compares 2020, which is a year with a multiple sigma mortality deviation, with 2021, which is a year with even an even higher multiple sigma deviation from the pre-pandemic five year trend. (See the Table in the link.) It is statistically incompetent to compare data with multiple-sigma deviations (2020) from the normal trend with data that has an even larger multiple sigma deviation from the normal trend. Yet that is what the CDC is doing. The only reason for doing that is to cover up the fact that 2021 is an even larger mortality deviation from 2019 than was 2020. The CDC must either know or strongly suspect why the mortality increased–otherwise there would be no point in trying to cover it up. The CDC would be trying to investigate the reason for the massive increase in US working age mortality in 2021 v. 2019 if it were dealing an honest game.
*Multiple sigma deviation–this is based off of standard deviations of data from a normal trend. The larger the deviation, the more sigmas are used to describe it.
