Deaths 2020

• Peer-reviewed research in Science Advances identifies 155,000 uncounted COVID-19 deaths in 2020-2021, raising official U.S. toll from 840,000 to nearly 1 million that period. • AI analysis of mortality data shows 16% undercount, totaling 1.2 million U.S. COVID deaths over six years. • Undercounts disproportionately affect Hispanic and communities of color, often from non-hospital deaths, impacting public health policy accuracy.

• Researchers using AI analyzed death certificates and estimated 155,000 additional unrecognized COVID-19 deaths outside hospitals in 2020-2021, raising the official toll of 840,000 by 16%. • The study compared symptomology of hospital deaths with those outside care, highlighting dramatic disparities in uncounted fatalities nationwide. • This undercounting underscores ongoing challenges in pandemic mortality tracking and public health surveillance across the U.S.
