The average lifespan in America dropped for the second year in a row in 2021, according to a Vital Statistics Rapid Release fact sheet published by the Centers for disease control and Prevention.

In the first two years of the COVID-19 pandemic, the estimated American lifespan was shortened by nearly three years. The last comparable decrease happened in the early 1940s, during the height of World War II.

Factors for the Decline

US officials blamed COVID-19 for about half the decline in 2021, a year when vaccinations became widely available but new coronavirus variants caused waves of hospitalizations and deaths. Other contributors to the decline are longstanding problems: drug overdoses, heart disease, suicide, and chronic liver disease. 

“It’s a dismal situation. It was bad before and it’s gotten worse,” said Samuel Preston, a University of Pennsylvania demographer.

Life expectancy is an estimate of the average number of years a baby born in a given year might expect to live, given death rates at that time, according to the CDC.

It is “the most fundamental indicator of population health in this country,” said Robert Hummer, a University of North Carolina researcher who studies population health patterns. 

According to researchers, U.S. life expectancy rose for decades, but progress stalled before the pandemic. It was 78 years and 10 months back in 2019. In 2020, it dropped to 77 years. Last year, it fell to about 76 years, 1 month.

The last time it was that low was in 1996.

Declines during the pandemic were worse for some racial groups, and some gaps widened. For example, life expectancy for American Indian and Alaskan Native people saw a decline of more than 6 1/2 years since the pandemic began and is at 65 years. In the same span, life expectancy for Asian Americans dropped by about two years and stands at 83.5.

Experts say there are many possible reasons for such differences, including lack of access to quality health care and a greater share of the population in lower-paying jobs that required them to keep working when the pandemic was at its worst.

The new report is based on provisional data. Life expectancy estimates can change with the addition of more data and further analysis. 

But it’s likely the declines in 2020 and 2021 will stand as the first two consecutive years of declining life expectancy in the U.S. since the early 1960s, officials said.

As Expected, After Pandemic – other sources

Report’s Findings

  • Life expectancy at birth for women in the United States dropped 0.8 years from 79.9 years in 2020 to 79.1 in 2021, while life expectancy for men dropped one full year, from 74.2 years in 2020 to 73.2 in 2021
  • Life expectancy for men dropped a full year, from about 74 years to 73.
  • The declines in life expectancy since 2019 are largely driven by the pandemic. COVID-19 deaths contributed to nearly three-fourths or 74% of the decline from 2019 to 2020 and 50% of the decline from 2020 to 2021.
  • White people saw the second biggest drop among racial and ethnic groups, with life expectancy falling one year, to about 76 years, 5 months. 
  • Black Americans had the third largest decline, falling more than eight months, to 70 years, 10 months.
  • Hispanic Americans had seen a huge drop in life expectancy in 2020 – four years. But in 2021, life expectancy for them dropped by about two months, to about 77 years, 7 months. Higher vaccination rates among Hispanics may have played a role.

Number of Suicides Increased Last Year

The report also suggests gains against suicide are being undone. 

U.S. suicides rose from the early 2000s until 2018. But they fell a little in 2019 and then more in 2020, the first year of the pandemic. 

The CDC’s report said suicide contributed to the decline in life expectancy in 2021, but it did not provide detail. According to provisional numbers from a public CDC database, the number of U.S. suicides increased last year by about 2,000, to 48,000. The U.S. suicide rate rose as well, from 13.5 per 100,000 to 14.1 – bringing it back up to about where it was in 2018.
