This paper quantifies the net impact (direct and indirect effects) of the pandemic on the United States population in 2020 using three metrics: excess deaths, life expectancy, and total years of life lost. The findings indicate there were 375,235 excess deaths, with 83% attributable to direct, and 17% attributable to indirect effects of COVID-19. The decrease in life expectancy was 1.67 years, translating to a reversion of 14 years in historical life expectancy gains. Total years of life lost in 2020 was 7,362,555 across the USA (73% directly attributable, 27% indirectly attributable to COVID-19), with considerable heterogeneity at the individual state level.
本文使用三种指标量化了 2020 年大流行对美国人口的净影响（直接和间接影响）：超额死亡人数、预期寿命和生命损失总数。研究结果表明，有 375235 人超额死亡，其中 83%归因于 COVID-19 的直接影响，17%归因于间接影响。预期寿命下降了 1.67 年，相当于历史上预期寿命增长的 14 年被逆转。2020 年，美国的生命损失总数为 7362555 年（73%直接归因于 COVID-19，27%间接归因于 COVID-19），各州之间存在很大差异。
