On Thursday, Misryoum newsroom reported that U.S. life expectancy climbed to 79 years in 2024—the highest mark in American history. It’s the kind of headline that sounds simple, but the reasons behind it are layered, from COVID-19’s retreat to slower death rates across the biggest causes of illness and injury.
In plain terms, life expectancy is an estimate of how many years a baby born in a given year might live, assuming the death rates of that period stay the same. For decades, the U.S. had been inching upward. It peaked in 2014, just shy of 79 years, then stayed relatively flat for a while—until the pandemic years.
As COVID-19 took hold, the gains stopped fast. Life expectancy plunged as the COVID-19 pandemic killed more than 1.2 million Americans. By 2021 it fell to just under 76 1/2 years, and since then it’s been rebounding—though not smoothly, and not evenly for everyone.
Misryoum newsroom reported that the 2024 improvement reflects not only the dissipation of the COVID-19 pandemic, but also waning death rates from major killers like heart disease, cancer, and drug overdoses. “It’s pretty much good news all the way around,” Robert Anderson, of the National Center for Health Statistics at the Centers for Disease Control and Prevention, said as part of the release of the 2024 data. Preliminary statistics suggest continued improvement in 2025, and that future-looking piece matters—because the best way to judge these numbers is not just as a one-time bounce, but as a trend.
The picture gets more complicated when you zoom in. Misryoum editorial desk noted that the shift also points to a lasting improvement in the drug overdose epidemic. Andrew Stokes, a researcher at Boston University, said the turnaround is real, but the U.S. still ranks below dozens of other countries. “There’s a lot more to be done,” he said. About 3.07 million U.S. residents died in 2024, roughly 18,000 fewer than the year before. Death rates declined across all racial and ethnic groups, and in both men and women.
Not every indicator moved dramatically. Misryoum analysis indicates that the infant mortality rate didn’t change significantly from 2023, when there were 560.2 infant deaths per 100,000 live births, to 2024, when there were 552.5. Heart disease stayed the nation’s leading cause of death, but the death rate dropped by about 3% for the second year in a row. Dr. Sadiya Khan, who treats and studies heart disease at Northwestern University, said advances in medical treatments and weight management are likely part of the explanation.
When it comes to injuries, the decline was steeper. Deaths from unintentional injuries—which includes drug overdoses—fell the most, dropping more than 14% in 2024. COVID-19, which had been the nation’s No. 3 killer only a few years earlier, dropped out of the top 10 in 2024. In a twist that always feels a little grim, COVID-19’s fall meant suicide moved into the top 10, even though suicides in 2024 declined. Homicides fell too, Misryoum newsroom reported.
Deaths statistics for 2025 aren’t finalized yet, but preliminary data suggest around 3.05 million deaths have been recorded. That number could rise as more death certificates are rounded up and analyzed, but Anderson said he expects last year will end up at least a slight improvement over 2024. In a hospital hallway—some days ago, I remember hearing that low monitor beep that gets you to look up—the trends in these reports can feel far away. Still, the data are made of real lives, and the record high in 2024 is not just a statistic. It’s a sign that, at least for now, the country is moving in the right direction—while the gap to other countries and the unfinished work on drug overdose remain very much there.
