Lead author Theresa Andrasfay, a postdoctoral scholar at the USC Leonard Davis School of Gerontology, and coauthor Noreen Goldman of Princeton University first examined the pandemic's effect on American life expectancy in October 2020. Their initial study, published in Proceedings of the National Academy of Sciences in January 2021, showed the largest single-year decline in life expectancy in at least 40 years and the lowest life expectancy estimated since 2003.

The updated analysis, which included the more than 380,000 US COVID-19 deaths in 2020 and used 2018 life expectancies as a comparison, indicates that COVID-19 reduced overall life expectancy by 1.31 years (up from the initial estimate of 1.13 years lost) to 77.43 years. The reductions in average lifespan are more than three times as large for Latinos (3.03 years) and twice as large for the Black population (1.90 years) compared to whites (0.94 years).
