What Is the Average Lifespan of an American Male?

The average American male lives to 76.5 years, based on 2024 data from the CDC. That’s up from 75.8 in 2023, continuing a rebound after several rough years driven by COVID-19 and the opioid crisis. While this number is climbing again, it still places American men well behind their peers in other wealthy nations.

How Male Life Expectancy Has Changed Over Time

In 1900, life expectancy at birth in the U.S. was just 47.3 years. That number reflected high rates of infant mortality, infectious disease, and limited medical care. The jump from 47 to 76.5 over a little more than a century is largely the result of cleaner water, vaccines, antibiotics, and improvements in maternal and infant care. Most of those early gains came from keeping children alive, not from extending old age.

The most recent disruption came between 2019 and 2022, when life expectancy dropped sharply. The COVID-19 pandemic hit men especially hard, and opioid-related deaths surged at the same time. A Johns Hopkins analysis published in The Lancet found that opioid deaths alone shaved 0.67 years off national life expectancy in 2022, up from 0.52 years in 2019. The pandemic period also disrupted social, economic, and health systems in ways that amplified drug overdose deaths. The 2024 figure of 76.5 represents a meaningful recovery, but male life expectancy still hasn’t returned to its pre-pandemic peak.

How the U.S. Compares to Other Countries

Among wealthy nations, the U.S. ranks last in male life expectancy. The average across comparable high-income countries is 80.5 years for men, a gap of four full years. That 5.3% difference persists even after age 65, where comparable countries exceed the U.S. by 5.5%. American men don’t just die younger overall; they also live fewer years in retirement than men in peer nations.

This gap exists despite the U.S. spending far more per person on healthcare than any other country. The shortfall is driven less by medical technology and more by factors like gun violence, drug overdoses, car accidents, obesity, and uneven access to preventive care.

Why Men Live Shorter Than Women

American women live to an average of 81.4 years, nearly five years longer than men. This gap shows up across almost every country in the world, which points to a combination of biology and behavior.

On the biological side, the Y chromosome develops mutations more frequently than X chromosomes. Women carry two X chromosomes, so if one has a harmful mutation, the other can compensate. Men don’t have that backup. Male fetuses are also less likely to survive in the womb, and developmental disorders are more common in boys. There’s even evidence that larger body size, which men tend to have, correlates with shorter lifespan across many species. Lower estrogen levels in men may also contribute to higher rates of heart disease, and men are 50% more likely than women to die of heart disease.

Behavioral differences widen the gap further. Men take more physical risks, leading to higher death rates from accidents, violence, and dangerous occupations like construction, firefighting, and military combat. Men are also far more likely to skip routine health screenings and less likely to have seen a doctor in the past year. The part of the brain responsible for judgment and impulse control develops more slowly in young men, which may partly explain higher rates of risky behavior like drunk driving and substance use in younger age groups. Men also commit suicide at higher rates than women, despite women experiencing higher rates of depression, a pattern often linked to cultural norms that discourage men from seeking mental health support. Social isolation plays a role too: men tend to have fewer and weaker social connections, and people with limited social ties have higher death rates.

Life Expectancy After Age 65

If you’re an American man who has already reached 65, your outlook is better than the “76.5” headline number suggests. That figure is calculated at birth and includes everyone who dies young from accidents, overdoses, and other causes. Once you’ve made it to 65, the Social Security Administration estimates you’ll live an additional 17.5 years on average, putting you at roughly 82 or 83.

That distinction matters for retirement planning, healthcare decisions, and long-term financial goals. Many men underestimate how long they’ll actually live past 65, which can lead to undersaving or making overly conservative assumptions about their remaining years.

What Shortens (and Lengthens) the Average

Life expectancy is a population-level average, not a personal prediction. Your own trajectory depends heavily on a handful of factors. Heart disease remains the leading killer of American men, and it’s closely tied to blood pressure, cholesterol, smoking, diet, and physical activity. These are also the areas where individual choices have the most impact.

Opioid overdoses have become a major driver of premature death, particularly among men in their 30s and 40s. Because life expectancy calculations weigh early deaths heavily, these losses pull the average down more than a death at 85 would. The same is true for car accidents, homicides, and suicides, all of which disproportionately affect men at younger ages.

On the other side, the factors most consistently linked to longer life are familiar: not smoking, maintaining a healthy weight, staying physically active, managing blood pressure and cholesterol, staying socially connected, and actually going to the doctor for preventive care. None of these are surprising, but the gap between knowing them and doing them is where much of the male life expectancy shortfall lives.
