Roughly one in five Americans dies before reaching age 65, though that fraction shifts dramatically depending on sex, race, income, and where a person lives. For men the odds are worse than for women, for Black Americans worse than for white Americans, and for the poor worse than for the affluent. What makes this figure particularly striking is that much of this early mortality is driven by preventable conditions, and the U.S. fares poorly by the standards of other wealthy nations.
How the Overall Numbers Break Down
Using CDC life tables and actuarial data from the Social Security Administration, a person born in the United States today has roughly an 18 to 22 percent chance of dying before their 65th birthday, depending on birth year and sex. Men face a substantially higher risk than women, largely because of higher rates of heart disease, accidents, suicide, and drug overdose. When public health researchers talk about “premature death,” they usually mean death before 65 or before 75, and the U.S. uses that 65-year threshold as a standard benchmark partly because it has long been tied to retirement eligibility and Medicare enrollment.
The concept of years of potential life lost, sometimes abbreviated YPLL, is one way researchers quantify the social cost of these early deaths. It estimates the average time a person would have lived had they not died prematurely, and it tends to highlight causes of death that strike younger adults more than older ones.1PubMed. Years of potential life lost (YPLL)–what does it measure? By that measure, causes like drug overdose and car accidents carry disproportionate weight compared with something like Alzheimer’s disease, which overwhelmingly kills people well past 65.
What Kills People Before 65
The leading causes of premature death in the U.S. overlap with but differ in emphasis from the leading causes of death overall. Heart disease and cancer top both lists, but accidents (including drug overdoses), chronic liver disease, and suicide rank much higher when you focus on deaths before 65. A major analysis of cause-specific mortality in U.S. adults listed the primary causes as diseases of the heart, malignant neoplasms, cerebrovascular diseases, chronic lower respiratory diseases, diabetes, accidents, Alzheimer’s disease, influenza and pneumonia, and kidney disease.2PubMed Central. The Association Between Obesity Class and Cause‐Specific Mortality by Age and Sex in US Adults Among those causes, heart disease and accidents carry an outsized share of early deaths relative to the others.
Heart disease deserves special attention because decades of progress in reducing premature cardiovascular deaths have stalled. After a long period of decline, premature heart disease mortality plateaued and in some groups began rising. Researchers have pointed to continued high rates of uncontrolled blood pressure, increasing prevalence of diabetes, and rising obesity as key obstacles to getting the trend moving downward again.3PubMed Central. US trends in premature heart disease mortality over the past 50 years: Where do we go from here? The frustrating part is that proven treatments and public health strategies exist for all three of those risk factors; the problem is one of implementation, not knowledge.
Firearm injuries also play a meaningful role. Because gun deaths disproportionately affect younger adults, they account for about 7 percent of all years of potential life lost before age 65, a share that is far larger than firearms’ share of total annual deaths would suggest.4PubMed Central. Firearm injuries in the United States This reflects the fact that homicide and suicide by firearm tend to kill people in their twenties through fifties, pulling the YPLL number steeply upward.
Racial and Ethnic Gaps
One of the starkest features of premature death in the U.S. is the racial gap. In 2022, Black adults had a premature mortality rate of 427 per 100,000, compared with 316 per 100,000 for white adults. A decade earlier the gap was already wide (309 vs. 247), and it grew significantly between 2012 and 2022, with premature death rates climbing about 38 percent for Black adults and about 28 percent for white adults.5JAMA Health Forum. Racial Disparities in Premature Mortality and Unrealized Medicare Benefits Across US States In most states the difference was statistically significant, with only a handful of exceptions.
The picture becomes even more complicated when you look beyond the Black-white comparison. During 1999 through 2016, midlife death rates rose not just among white Americans but also among American Indian and Alaska Native populations. Black, Hispanic, and Asian American groups initially saw declines, but those improvements stalled around 2009 to 2011 and in some cases reversed.6PubMed Central. Changes in midlife death rates across racial and ethnic groups in the United States: systematic analysis of vital statistics Drug overdoses drove many of those increases across all racial and ethnic groups, but rising deaths from alcohol-related conditions and suicides also contributed.
A separate trend analysis found a pattern that was consistent across age groups: racial and ethnic mortality disparities had been narrowing for roughly the first decade of the 2000s, but then began widening again around 2009 to 2012. Adults aged 35 to 64 were among the groups where this reversal reached statistical significance, meaning the convergence in death rates across racial groups didn’t just slow down but actively went into reverse.7American Journal of Preventive Medicine. Trends in Racial and Ethnic Mortality Disparities by Age Group in the United States The reasons for this inflection are still debated, but the Great Recession and its aftermath, uneven recovery in employment and wages, and the accelerating opioid crisis all likely played a role.
Income, Education, and Wealth
Socioeconomic status is one of the strongest predictors of whether someone will reach 65. Education alone is associated with enormous differences in life expectancy. Adults with at least a master’s degree had a remaining life expectancy at age 18 that was nearly 15 years longer than adults who never finished high school, and about 8 years longer than those with only a high school diploma.8PubMed Central. Marked Disparities in Life Expectancy by Education, Poverty Level, Occupation, and Housing Tenure in the United States, 1997-2014 Those gaps held across gender and racial groups.
Poverty amplifies the risk further. People living below the federal poverty line had a remaining life expectancy at age 18 that was roughly 10.5 years shorter than people with incomes at four times the poverty threshold or above. Even modest income differences mattered: those at one to two times the poverty level still faced nearly 9 fewer years of expected life.8PubMed Central. Marked Disparities in Life Expectancy by Education, Poverty Level, Occupation, and Housing Tenure in the United States, 1997-2014
Wealth, which includes assets like home equity and savings rather than just current income, may be an even stronger predictor of dying before 65 than education or occupation alone. One study found that before age 65, the gap in mortality risk between the wealthiest and poorest groups was larger than the gap for any other single socioeconomic measure. A composite index combining income, education, occupation, and wealth showed a threefold or greater difference in risk of death before 65 between the top and bottom groups.9JAMA Network Open. Assessment of Mortality Disparities by Wealth Relative to Other Measures of Socioeconomic Status Among US Adults The implication is that accumulated financial security, not just a college degree or a good paycheck, acts as a buffer against early death through multiple channels at once: better healthcare access, lower chronic stress, safer housing and neighborhoods, and more ability to manage health problems before they become fatal.
The Rural Penalty
Where you live within the United States matters for your odds of dying young, and the gap between rural and urban counties has been widening. A CDC analysis covering 2010 through 2022 found that the percentage of preventable premature deaths from the five leading causes was consistently higher in rural counties than in urban ones. The most rural counties (classified as “noncore” in the federal system) had higher rates of preventable premature death from heart disease, cancer, unintentional injuries, chronic lower respiratory diseases, and stroke than even the most urban metropolitan counties across every year of the study period.10PubMed Central. Preventable Premature Deaths from the Five Leading Causes of Death in Nonmetropolitan and Metropolitan Counties, United States, 2010-2022
Several forces converge in rural America to push premature death rates up. Hospitals and clinics are farther away, meaning that heart attacks, strokes, and traumatic injuries are less likely to receive timely treatment. Rates of smoking, obesity, and physical inactivity tend to be higher. Poverty is more concentrated. And the opioid and methamphetamine crises hit rural communities particularly hard, adding drug-overdose deaths on top of already elevated rates of chronic disease mortality.
Deaths of Despair
The phrase “deaths of despair” was coined to describe the rising tide of suicides, fatal drug overdoses, and alcohol-related deaths among working-age Americans, particularly since the early 2000s. A scoping review of the research identified a progressive increase in deaths from all three of these causes over the past two decades in the U.S.11PubMed Central. Deaths of Despair: A Scoping Review on the Social Determinants of Drug Overdose, Alcohol-Related Liver Disease and Suicide Social determinants such as unemployment, lack of social cohesion, economic inequality, and housing instability have been linked to these deaths.
The relationship between economic conditions and these deaths is real but nuanced. Research using labor market data from 2003 through 2017 found that a one-percentage-point rise in the aggregate employment rate decreased current-year non-drug suicides by about 1.7 percent among working-age adults. The protective effect was concentrated among working-age men and reflected both individual employment gains and the broader effects of local economic growth. Interestingly, the same study found no consistent evidence that short-term economic swings affected drug or alcohol-related mortality, suggesting those trends are driven more by long-term structural changes, drug supply dynamics, and other factors than by year-to-year job fluctuations.12PubMed Central. “Deaths of despair” over the business cycle
This distinction matters for how we think about solutions. Suicide prevention responds partly to near-term economic improvement, but the drug overdose crisis has its own momentum, driven by the availability of fentanyl and other synthetic opioids. Treating all three causes as a monolithic “despair” problem, while politically useful, can obscure the fact that they have partly overlapping but partly independent drivers.
How the U.S. Compares Internationally
The U.S. stands out among wealthy nations for its high rate of premature death. One study published in the BMJ found that the U.S. premature death rate was roughly double that of France.13PubMed. Premature death rate in US is almost double that in France, study shows This gap isn’t explained by a single cause; instead, the U.S. performs worse across a range of categories including cardiovascular disease, injuries, and drug-related deaths. Countries with universal healthcare systems, lower rates of gun violence, and stronger social safety nets consistently outperform the U.S. on this metric.
Projections through 2030 suggest that U.S. premature death rates will continue declining on average, with women’s rates projected to fall from about 250 per 100,000 in 2016 to about 202 per 100,000 by 2030, and men’s rates from about 420 per 100,000 to about 340 per 100,000. But these projected improvements vary enormously by racial and ethnic group, meaning the international gap may narrow for some Americans and persist or worsen for others.14PubMed Central. Premature Death Rates in the United States: Projections through 2030
Health Insurance and Access to Care
Lack of health insurance is itself a risk factor for dying before 65. The evidence from multiple research designs converges on the conclusion that health insurance coverage reduces mortality. Across the available studies, the odds of dying among insured people relative to uninsured people ranged from about 0.71 to 0.97, meaning insurance was associated with somewhere between a modest and a substantial reduction in the risk of death.15PubMed. The Relationship of Health Insurance and Mortality: Is Lack of Insurance Deadly? A more recent review reinforced that finding, concluding that credible evidence from multiple data sources supports the link between gaining insurance and lower mortality.16PubMed. The Impact of Health Insurance on Mortality
This matters for premature death specifically because people under 65 who are not yet eligible for Medicare are the ones most likely to be uninsured. Medicaid expansion under the Affordable Care Act reduced uninsurance rates in states that adopted it, and research has linked expansion to measurable decreases in mortality, particularly from conditions that are treatable when caught early, like diabetes and cardiovascular disease. In states that did not expand Medicaid, working-age adults in the coverage gap have no affordable insurance option, which contributes to the geographic variation in premature death rates discussed earlier.
COVID-19 and the Recent Spike
The COVID-19 pandemic punched a visible hole in premature death trends. Midlife adults between 40 and 64 experienced significant excess mortality during 2020 and 2021. Among men, the 55 to 59 age group saw one of the highest impacts, partly because that group’s death rate had been declining steadily in the years just before the pandemic, making the reversal especially sharp.17Aging and Health Research. Impact of COVID-19 on mortality and excess mortality of midlife from 40 to 64 age groups The virus itself was only part of the story: delayed medical care, disrupted substance use treatment, increased alcohol consumption, and rising overdose deaths all contributed to the spike in under-65 mortality during the pandemic years.
While the worst of the pandemic’s acute mortality impact has receded, some of the collateral damage persists. Rates of drug overdose deaths, already elevated, accelerated during and after the pandemic. Screening rates for cancer dropped during lockdowns, and some researchers worry that delayed diagnoses will translate into additional premature cancer deaths in the years ahead. Whether these disruptions produce a lasting upward shift in premature mortality or merely a temporary bump that reverses as healthcare access normalizes remains an open question.
Childhood Adversity and the Long Fuse
Some of the roots of premature death reach back to childhood. Adverse childhood experiences, a category that includes abuse, neglect, household dysfunction, parental separation, and poverty, are linked to a significantly higher risk of dying young. One study found that adults who experienced six or more such adversities were about 2.4 times more likely to die before age 65 than adults with no such history, after accounting for other factors.18PubMed. Adverse childhood experiences and the risk of premature mortality
The relationship between childhood adversity and early death appears to be dose-dependent: each additional adverse experience adds roughly 4 percent to the overall risk of dying in adulthood, and this association holds across both sexes.19Child Abuse & Neglect. Adverse childhood experiences and all-cause mortality risk in adulthood A five-decade prospective study found that children who grew up in poverty with parental separation had about 50 percent higher odds of premature death compared with those who experienced low adversity, while children with four or more adverse experiences had about 45 percent higher odds.20The Lancet Regional Health – Americas. Adverse childhood experiences and premature mortality through mid-adulthood: A five-decade prospective study
The pathways connecting childhood trauma to early death are both behavioral and biological. Children who grow up in chaotic or abusive environments are more likely to smoke, use drugs, become obese, and engage in risky behavior as adults. But there are also direct physiological effects: chronic stress in childhood alters hormonal and immune system development in ways that accelerate cardiovascular disease, diabetes, and other chronic illnesses decades later. Premature death, in other words, can have a very long fuse.
Poverty, Blood Pressure, and the Global View
Zooming out to a cross-national perspective offers a useful sense of which risk factors carry the most weight. A statistical analysis of cardiovascular death before age 65 across 168 countries ranked the attributable risks of multiple variables. High blood pressure and air pollution each contributed about 9 percent of the risk. Poverty contributed about 8 percent, and tobacco about 7 percent. Being male carried about 6 percent of the risk, while excessive alcohol consumption contributed less than half a percent.21PubMed Central. Cardiovascular Disease Death Before Age 65 in 168 Countries Correlated Statistically with Biometrics, Socioeconomic Status, Tobacco, Gender, Exercise, Macronutrients, and Vitamin K These figures represent global averages and don’t translate directly to the U.S., but they reinforce a consistent theme: poverty, blood pressure, and tobacco are among the most potent modifiable drivers of dying young, and the U.S. has room to improve on all three.
What makes the American situation frustrating is that most of the top killers before 65 are at least partly addressable. Blood pressure can be controlled with inexpensive medications. Smoking rates have fallen but still hover above 10 percent of the adult population. Drug overdose deaths could be reduced with wider access to medication-assisted treatment and harm-reduction programs. The gap between what is medically possible and what the U.S. actually achieves in preventing premature death remains wide, and that gap is measured in hundreds of thousands of lost years of life.
