Go see the charts at the source. And the CDC info that Steve could only get from a CDC leaker.
I only see one chart about mortality at the source link. That’s a chart of percent changes in mortality from 2020 to 2021. It has a sharp spike up to a maximum in September, which is hard to explain completely by lockdowns in 2020. But a substantial part of the increase from 2020 could be caused by a dip in deaths from traffic accidents and homicides in 2020 (resulting from lockdowns and people staying home). Again, we need to see the original data for mortality in 2020 and 2021 for people between 18 and 55. Until we have that data, it’s difficult to reach any definitive conclusions.
