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

The updated analysis, published in PLOS ONE, indicates that U.S. life expectancy at birth decreased by 2.2 years from 78.8 in 2019 to 76.6 in 2021. The estimated decrease in life expectancy for 2021 is 0.6 years larger than the decrease observed in 2020, Andrasfay said.
