Post-1970 Americans Face Higher Death Rates as U.S. Life Expectancy Gains Slow to 0.26 Years

Summary
Americans born after 1970 are already dying at higher rates from heart disease, cancer and external causes than earlier generations did at the same ages, according to a PNAS study tracking cohorts from the 1890s through the 1980s.
The analysis identifies Americans born in the 1950s as the turning point: cohorts born before them generally saw improving survival, while each generation since has fared progressively worse across major causes of death.
A separate nationwide setback began around 2010 and hit nearly all adults, with stalled progress against cardiovascular disease driving much of the deterioration after decades of improvement.
Between 2010 and 2019, U.S. life expectancy rose just 0.26 years versus an average 1.78 years per decade over the prior five decades; overdose deaths, obesity-linked cancers and worsening suicide trends added pressure.
Researchers warn that if these cohort patterns persist as post-1970 Americans age, the U.S. could face an unprecedented long-run stagnation or even sustained decline in life expectancy.

Overview
U.S. life expectancy has reached a record high, rising from 78.4 years in 2023 to 79.0 years in 2024, with early data suggesting further gains ahead. This improvement is seen not only at birth but also at age 65, where Americans can now expect nearly two decades of retirement. Both men and women experienced increases in life expectancy at age 65, and the gap between the sexes has narrowed slightly. These positive trends highlight a national rebound, though the report notes that challenges remain, especially when comparing U.S. outcomes to those of other developed countries.
