In order to provide a more accurate measure of the impact of the pandemic, this CDC report estimates all-cause excess deaths NYC between March 11–May 2, 2020.
The authors defined excess deaths as the number of deaths above expected seasonal baseline levels, regardless of the reported cause of death. They determined excess deaths for the period of March 11–May 2, 2020, using mortality data from the period January 1, 2015–May 2, 2020 and calculated the difference between the seasonally expected baseline number and the reported number of all-cause deaths.
They report a total of 32,107 deaths during this time period. Of these deaths, 24,172 (95% confidence interval = 22,980–25,364) were found to be in excess of the seasonal expected baseline. Included in the 24,172 deaths were 13,831 (57%) laboratory-confirmed COVID-19–associated deaths and 5,048 (21%) probable COVID-19–associated deaths, leaving 5,293 (22%) excess deaths that were not identified as either laboratory-confirmed or probable COVID-19–associated deaths.
