Roughly 1 in 5 American men and 1 in 8 American women will die before reaching age 65, based on the Social Security Administration’s most recent actuarial life tables. More precisely, a 20-year-old man has about a 21.6% chance of dying before 65, while a 20-year-old woman faces about a 13% chance. Those numbers make the U.S. an outlier among wealthy nations, and the gap between men and women, between states, and between income levels is striking.
The Numbers by Sex
The SSA’s 2022 period life table, used in its 2025 Trustees Report, tracks what happens to a hypothetical group of 100,000 people born alive. Of 100,000 males, roughly 98,698 survive to age 20, but only 77,402 make it to 65. That means about 21,300 out of every 100,000 men die during their working years. For women, 99,094 survive to age 20 and 86,231 reach 65, a loss of roughly 12,900 per 100,000. The gap comes down to higher rates of heart disease, accidental injury, and suicide among men across nearly every age bracket.
What Kills People Before 65
The leading causes shift dramatically depending on the decade of life. For Americans between 15 and 34, unintentional injuries (a category dominated by drug overdoses and car crashes) are the top killer by a wide margin. Suicide and homicide round out the top three for younger adults.
Starting in the mid-30s, chronic disease takes over. Heart disease and cancer become the leading causes of death from age 35 onward and dominate from the mid-40s through the early 60s. Liver disease, largely driven by alcohol use, enters the top five for people in their 30s through 50s. Diabetes becomes a major factor in the 45 to 54 age group.
In practical terms, this means the risks you face before 65 break into two broad categories: injuries and self-harm when you’re younger, and cardiovascular disease and cancer as you move into middle age. Both categories are heavily influenced by behavior, environment, and access to healthcare.
Where You Live Changes Your Odds
The chance of dying before 65 varies enormously across the country. Research from Syracuse University’s Lerner Center for Public Health found that residents of Minnesota, California, New York, and Massachusetts have the lowest rates of premature death. At the other end, a cluster of Southern states, including West Virginia, Mississippi, Alabama, Kentucky, Tennessee, Louisiana, Arkansas, and Oklahoma, have rates so high that more than 1 in 5 people born in those states will not survive to 65 under current conditions.
That 1-in-5 figure for the worst-performing states is close to the national average for men, meaning women in those states face risks that look more like the national male average. The geographic pattern tracks closely with poverty rates, access to healthcare, smoking prevalence, and rates of drug overdose.
Income and Premature Death
County-level CDC data shows a clear relationship between income and the likelihood of dying young. Low-income counties (with median household incomes at or below roughly $30,000) had premature death rates of 496 per 100,000 residents, compared to 351 per 100,000 in high-income counties. That translates to about 41% more premature deaths in the poorest communities compared to the wealthiest ones. Living in a low-income county was associated with 18% higher premature mortality compared to middle-income areas, while high-income counties saw 20% lower rates.
These differences reflect compounding disadvantages: less access to preventive care, higher rates of smoking and obesity, more dangerous working conditions, greater exposure to environmental hazards, and fewer resources to manage chronic conditions before they become fatal.
Recent Trends
Death rates for every age group under 65 dropped between 2023 and 2024, some by significant margins. The largest improvement was among 25-to-34-year-olds, whose death rate fell nearly 16%, from 148.1 to 124.5 per 100,000. Rates for 15-to-24-year-olds dropped almost 13%. Even the 55-to-64 group, where rates are highest, saw a 4.4% decline.
These recent declines follow a turbulent period. The COVID-19 pandemic pushed midlife death rates sharply upward in 2020 and 2021, and the ongoing overdose crisis had already been driving up mortality among working-age adults for over a decade before that. The 2024 numbers suggest a partial recovery, but death rates for younger and middle-aged Americans remain higher than they were in 2019 for several age groups.
How the U.S. Compares Internationally
The U.S. consistently ranks poorly among high-income countries on premature mortality. While exact comparisons depend on how “premature” is defined, peer nations in Western Europe and East Asia typically see significantly lower shares of their populations dying before 65. Countries with universal healthcare systems, lower rates of gun violence, stricter drug policies, and stronger social safety nets tend to lose fewer people during working age. The American combination of high unintentional injury rates, limited healthcare access for lower-income adults, and elevated cardiovascular disease burden creates a gap that has widened over the past two decades.
