U.S. life expectancy fell by a year in the first half of 2020, CDC report finds
As the Covid-19 pandemic took hold, life expectancy in the United States dropped one full year during the first half of 2020, according to a new Centers of Disease Control and Prevention report, with even greater declines seen among Black and Hispanic people.
Preliminary data from the agency’s National Center for Health Statistics released Thursday mark a reversal of incremental gains over the past few years. Life expectancy at birth for the total U.S. population declined from 78.8 years in 2019 to 77.8 years for January through June 2020. During that same time period, life expectancy for non-Hispanic Black people decreased by 2.7 years (74.7 to 72); for Hispanic individuals, 1.9 years (81.8 to 79.9); and for non-Hispanic white people, 0.8 years (78.8 to 78).
The Covid-19 pandemic is likely responsible for “the majority of the decline,” said Elizabeth Arias, a health scientist at the Mortality Statistics Branch of the NCHS and the lead author of the report.

Arias said it’s also possible that some of the decline can be indirectly attributed to the pandemic, such as the rise in drug overdose deaths.
The new life expectancy projection is the lowest it’s been since 2006 — and it had been on the rise in both 2018 and 2019.
“Life expectancy has mostly been increasing from year to year,” said Arias. Even before 2018, Arias said life expectancy estimates tended to be almost the same or decrease very slightly, for instance by a few tenths of a year.
Among males, life expectancy at birth fell 1.2 years, from 76.3 years in 2019 to 75.1 during the first half of 2020. For females, it dropped 0.9 years, from 81.4 years to 80.5. The gap in life expectancy between sexes increased from 5.1 years in 2019 to 5.4 in 2020.
Looking further at racial disparities in the data, the gap in life expectancy between non-Hispanic white and Black people widened from 4.1 years in 2019 to six years in the first half of 2020 — the largest gap since 1998.
“The disparities between those populations have been declining consistently, since we began estimating life expectancy, which goes back to 1900,” she said.
The gap between Hispanic and white non-Hispanic individuals narrowed, however, from three years in 2019 to 1.9 in 2020.
Non-Hispanic Black males experienced the highest decline in life expectancy — three years — of any race and sex subgroup in the new analysis, followed by Hispanic males (2.4 years), non-Hispanic Black females (2.3 years), and Hispanic females (1.1 years).
The data come with several caveats: The provisional count means that the report doesn’t capture the full impact of the Covid-19 pandemic in 2020. Arias said data from the entire year will be released in May or June, and finalized versions of 2020 data on mortality and life expectancy, which the NCHS publishes annually, will be released by the end of this year or early next year.
And because the early part of the Covid-19 pandemic largely affected urban areas, where people of color are more likely to live, overall life expectancy could be an underestimate. Arias said data from the full year will likely better reflect the impact of the pandemic on life expectancy, since the pandemic eventually spread throughout both urban and rural areas.
Arias said the differences in life expectancy among racial groups were particularly striking, as the Covid-19 pandemic took a disproportionate toll on communities of color.
“There’s a big difference there,” Arias said. “That was one of things that stuck out the most.”
