US life expectancy plunged again in 2021, down nearly a year

U.S. life expectancy dropped for two consecutive years in 2020 and 2021, marking the first such trend since the early 1920s, according to a new government report.

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.
