Life expectancy in US plunged again in 2021
COVID-19, overdoses, diseases most to blame
NEW YORK – U.S. life expectancy dropped for the second consecutive year in 2021, falling by nearly a year from 2020, according to a government report being released Wednesday.
In the first two years of the COVID-19 pandemic, the estimated American lifespan has shortened by nearly three years. The last comparable decrease happened in the early 1940s, during the height of World War II.
Centers for Disease Control and Prevention 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.
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. It is “the most fundamental indicator of population health in this country,” said Robert Hummer, a University of North Carolina researcher focused on population health patterns.
U.S. life expectancy rose for decades, but progress stalled before the pandemic.
It was 78 years, 10 months 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 61⁄2 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 831⁄2.
Experts say there are many possible reasons for such differences, including lack of access to quality health care, lower vaccination rates, 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, CDC officials said.
The report also suggests gains against suicide are being undone. It 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.
