So in these data (remember, the numbers are updated regularly, we’re looking at March 1 to September 1 only, and this is a rough-and-ready calculation), we have 1,641,133 All-Cause deaths in comparison to a baseline 2015-2019 average of 1,359,816. In this period the raw excess is 281,317 deaths. COVID-19 was listed as a cause of 179,303 of these, leaving a deficit—a remaining excess—of 102,014. Overall excess mortality from March 1st to September 1st is 17.1% above the baseline, with COVID-19 accounting for 10.9 of those percentage points, with a 6.22 percentage point excess distributed across other causes.
