US 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, the AP reports. 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.
“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. 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. US 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.
The new report is based on provisional data. Life expectancy estimates can change with the addition of more data and further analysis. For example, the CDC initially said life expectancy in 2020 declined by about 1 year 6 months. But after more death reports and analysis came in, it ended up being about 1 year 10 months. But it's likely the declines in 2020 and 2021 will stand as the first two consecutive years of declining life expectancy in the US since the early 1960s, CDC officials said. Life expectancy for women in the United States dropped about 10 months, from just under 80 years in 2020 to slightly more than 79 in 2021. Life expectancy for men dropped a full year, from about 74 years to 73. (Click for more from the report, including life expectancy gaps between racial groups.)
