U.S. life expectancy rose in 2022, but it remains below its pre-pandemic level

S. life expectancy rose last year — by more than a year — but still isn’t close to what it was before the Covid-19 pandemic.

The 2022 rise was mainly due to the waning pandemic, Centers for Disease Control and Prevention researchers said Wednesday. But even with the large increase, U.S. life expectancy is only back to 77 years, 6 months — about what it was two decades ago.

Life expectancy is an estimate of the average number of years a baby born in a given year might expect to live, assuming the death rates at that time hold constant. The snapshot statistic is considered one of the most important measures of the health of the U.S. population. The 2022 calculations released Wednesday are provisional, and could change a little as the math is finalized.

For decades, U.S. life expectancy rose a little nearly every year. But about a decade ago, the trend flattened and even declined some years — a stall blamed largely on overdose deaths and suicides.
