BACKGROUNDThe end of the public health emergency provides an opportunity to fully describe disparities during the Covid-19 pandemic.METHODSIn this retrospective cohort analysis of US deaths during the Covid-19 public health emergency (March 2020-April 2023), all-cause excess mortality and years of potential life lost (YPLL) were calculated by race or ethnicity overall and by age groups (ages <25 years, 25-64 years, ≥65 years). Temporal correlations with Covid-19-specific mortality were measured.RESULTS>1.38 million all-cause excess deaths and ~23 million corresponding YPLL occurred during the pandemic. Had the rate of excess mortality observed among the White population been observed among the total population, >252,300 (18%) fewer excess deaths, and >5,192,000 fewer (22%) YPLL would have occurred. The highest excess mortality rates were among the American Indian/Alaska Native (AI/AN, 822 per 100,000; ~405,700 YPLL) and the Black (549 per 100,000; ~4,289,200 YPLL) populations. The highest relative increase in mortality was observed in the AI/AN population (1.34; 95% CI 1.31-1.37), followed by Hispanic (1.31; 95% CI 1.27-1.34), Native Hawaiian or Other Pacific Islander (1.24; 95% CI 1.21-1.27), Asian (1.20; 95% CI 1.18-1.20), Black (1.20; 95% CI 1.18-1.22) and White (1.12; 95% CI 1.09-1.15) populations. Greater disparities occurred among children and adults <65 years.CONCLUSIONSExcess mortality occurred in all groups during the Covid-19 pandemic, with disparities by race and ethnicity, especially in younger and middle-aged populations. >252,000 and 5.2 million fewer YPLL would have been observed had increases in mortality among the total population been similar to the White population.
