For decades, conversations about career growth and women’s health ran on parallel tracks. That separation is no longer sustainable. As more women occupy leadership roles, executive positions, and entrepreneurial ventures, the mid-career transition known as perimenopause has become impossible to ignore. In the United States, perimenopause—the years of hormonal fluctuation leading up to menopause—most often begins between ages 35 and 55. This window overlaps almost exactly with the period of peak earning power, maximum career responsibility, and highest potential for advancement. The result is a collision of biology and professional demand that many women experience as a sudden, unexplained decline in focus, energy, and resilience. Generic wellness advice is not enough. What is required is a deliberate strategy that protects cognitive performance, leverages available legal and workplace protections, and safeguards long-term financial security.

The Longevity Gap: Why U.S. Women Live Longer—and Why It's Shrinking
Women still have a meaningful life-expectancy advantage in the United States. The latest national data, however, show that the difference between women and men is becoming smaller. Here's what the numbers tell us—and what they do not tell us.
Women's longevity is shaped by a combination of biology, behavior,
healthcare, social conditions and broader public-health factors.
How long people live is influenced by much more than biology. Access to healthcare, income, education, working conditions, behavior, chronic disease, injury risk and the environment around us can all influence population health. One of the clearest patterns in U.S. mortality statistics is that women have historically lived longer than men.
But that advantage is not fixed. According to final 2024 data from the CDC's National Center for Health Statistics (NCHS), life expectancy at birth was 81.4 years for U.S. females and 76.5 years for U.S. males. That represents a difference of 4.9 years. In 2023, the difference was 5.3 years, meaning the gap narrowed by 0.4 year in 2024.
That change raises an important question: if women still live longer on average, why is the longevity gap getting smaller? The answer is complicated. It involves changes in mortality among men, chronic diseases affecting both sexes, behavioral patterns, healthcare, socioeconomic conditions and biological differences.
Key Takeaways
- U.S. women had a life expectancy of 81.4 years in 2024.
- U.S. men had a life expectancy of 76.5 years in 2024.
- The female–male life-expectancy gap was 4.9 years in 2024, down from 5.3 years in 2023.
- Women's longer average lifespan cannot be explained by one biological factor. Biology, behavior, healthcare and social conditions all matter.
- Living longer does not automatically mean spending more years in good health. Healthspan and quality of life are also important.
What the Latest U.S. Numbers Tell Us
The most recent final mortality data from the CDC show that life expectancy increased for both women and men between 2023 and 2024. However, the increase was larger for men, which is why the female–male gap became smaller.

Why Have Women Historically Lived Longer?
The female longevity advantage is not the result of one simple cause. Researchers have examined biological, behavioral and social explanations, and the evidence points to an interaction between many factors.
Biological differences may play a role
Sex-related biological differences may influence cardiovascular health, immune responses, metabolism and other processes associated with aging. Hormones, chromosomes and differences in biological aging have all been studied as possible contributors to the longevity difference.
However, it would be misleading to describe one biological mechanism as the definitive reason women live longer. Human longevity is influenced by multiple interacting factors, and population differences cannot be reduced to biology alone.
Behavior and risk exposure also matter
Differences in health-related behaviors and exposure to certain risks can influence mortality. Smoking, alcohol use, occupational hazards, road injuries, violence, substance use and other external causes of death have not affected women and men in exactly the same way.
These patterns can be especially important because deaths occurring earlier in adulthood have a larger effect on life expectancy than deaths occurring at very advanced ages.
Healthcare and prevention contribute too
Women and men may differ in when and how they interact with healthcare services. Preventive care, screening, treatment of chronic conditions and timely management of health problems can all influence outcomes.
Healthcare utilization is only one part of the picture, however. The ability to obtain care, afford medication, take time away from work, access healthy food and live in a safe environment can also shape health outcomes.
Why Is the Longevity Gap Shrinking?
The latest numbers provide an important clue. Between 2023 and 2024, female life expectancy increased by 0.3 year, while male life expectancy increased by 0.7 year. As a result, the difference between the two groups decreased from 5.3 years to 4.9 years.
A narrowing gap does not mean that women are suddenly losing their longevity advantage. Women continued to have the higher life expectancy in 2024. Instead, the change means that mortality improved more for men than for women during that particular period.
The important distinction:
A shrinking gap can happen because one group gains more years, because
mortality patterns change differently between groups, or because both
happen at the same time. A single year's movement should therefore be
interpreted in the context of longer-term trends rather than treated as
proof of a permanent reversal.
Several forces can influence the difference
- Changes in premature mortality: Deaths occurring among younger and middle-aged adults can have a disproportionate effect on life expectancy.
- Chronic disease: Cardiovascular disease, cancer, diabetes and other chronic conditions influence mortality patterns for both sexes.
- External causes: Injuries, overdoses and other external causes of death can affect male mortality particularly strongly in some age groups.
- Changes in healthcare and prevention: Improvements in diagnosis, treatment and prevention can affect mortality differently across populations.
- Social and economic conditions: Employment, income, education, housing, environment and access to healthcare all contribute to population health.
The broader lesson is that the longevity gap is not a fixed biological constant. It can change as health risks, medical care, behavior and social conditions change.
What Happens After Age 65?
Life expectancy at birth is only one way to look at longevity. Another useful measure is the number of additional years people are expected to live after reaching age 65.
In 2024, the CDC estimated remaining life expectancy at age 65 at 20.8 years for females and 18.4 years for males. The female–male difference at age 65 was therefore 2.4 years.
This is different from the 4.9-year gap at birth. It illustrates why longevity statistics should always be interpreted in context: the size of the difference depends on the age at which life expectancy is measured.
Life Expectancy Is Not the Same for Every U.S. Population
National averages can hide substantial differences between populations. Life expectancy varies by race and Hispanic origin, geography, socioeconomic circumstances and other factors.
These differences should not be interpreted as biological rankings. Population health is shaped by a complex combination of income, education, healthcare access, neighborhood conditions, occupational exposures, environmental factors, chronic disease, discrimination and many other influences.
For that reason, this article does not present a simple ranking of racial or ethnic groups as though one number could explain the health experience of every woman. The CDC's mortality and life-table datasets provide the appropriate context for examining differences between populations.
Life expectancy is a population-level statistic and does not predict an
individual's lifespan.
Heart Disease Remains a Major Concern for Women
Living longer does not mean women are protected from serious chronic disease. Heart disease remains the leading cause of death among women in the United States.
According to the CDC, heart disease was responsible for 304,970 deaths among U.S. women in 2023, representing about one in five female deaths that year.
Important cardiovascular risk factors include high blood pressure, high cholesterol, diabetes, smoking, physical inactivity and other individual and environmental factors. Women can also experience heart disease differently at different stages of life.
The practical lesson is not that every woman needs the same medical screening schedule. Rather, cardiovascular risk should be discussed with a healthcare professional based on age, family history, symptoms, existing conditions and other individual factors.
The Biological Side of Female Longevity
Biology is one part of the longevity story. Researchers have investigated the possible roles of sex hormones, sex chromosomes, immune function, cellular aging and other biological differences.
Estrogen, for example, has important effects on several body systems, including the cardiovascular system. However, it would be inaccurate to turn this into a simple claim that estrogen alone explains women's longer lives. Hormonal changes across the life course are complex, and individual health outcomes vary considerably.
The strongest explanation is therefore a combination of biology and lived experience rather than a single "female longevity gene" or one protective hormone.
Living Longer Does Not Always Mean Living Healthier
One of the most important distinctions in conversations about longevity is the difference between lifespan and healthspan.
Lifespan refers to how long a person lives. Healthspan refers more broadly to the years spent in relatively good health and with the ability to participate in everyday life.
A longer average lifespan is valuable, but the quality of those additional years matters too. Chronic disease, mobility limitations, cognitive problems and loss of independence can affect later life even when a person reaches an advanced age.
A better question than "How long will I live?" is often:
"What can I do to improve the chances of remaining healthy, independent
and active as I age?"
Practical Ways to Support Healthy Aging
No lifestyle strategy can guarantee a particular lifespan. However, several broadly established health behaviors can support cardiovascular, metabolic, muscular and overall wellbeing.
-
Know your cardiovascular risk factors.
Keep track of health measures that your healthcare professional recommends, such as blood pressure, cholesterol and blood glucose. Ask what your personal risk factors mean rather than relying on population averages. -
Stay physically active.
Regular movement supports cardiovascular fitness, muscle function, mobility and overall health. Include activities appropriate for your age, abilities and health status. -
Protect muscle and bone strength.
Resistance and weight-bearing activities can be useful components of healthy aging. If you have an injury, chronic condition or other limitation, ask a qualified professional how to exercise safely. -
Build a balanced eating pattern.
A varied diet that includes vegetables, fruits, whole grains, legumes, nuts, adequate protein and other nutrient-rich foods can support overall health. Individual dietary needs vary. -
Protect sleep and social wellbeing.
Consistent sleep, meaningful relationships and opportunities for social connection are important parts of overall wellbeing. Persistent sleep or mental-health concerns deserve professional attention.
Healthy aging involves many factors, including preventive healthcare,
physical activity, nutrition and social wellbeing.
Why Social and Economic Conditions Matter
Longevity is not determined entirely by individual choices. Where a person lives, works and ages can affect the opportunities available to maintain good health.
Access to healthcare, affordable medicines, nutritious food, safe housing, transportation, education, stable employment and clean environments can all influence health outcomes.
This is why telling people simply to "make healthier choices" can be incomplete. Personal behavior matters, but health is also shaped by the circumstances in which people make those choices.
What the Longevity Gap Means for Women
The latest statistics provide both good news and an important reminder. Women continue to have a longer average life expectancy than men in the United States. At the same time, the advantage is not permanent or guaranteed.
The narrowing gap also demonstrates why longevity should not be treated as a competition between women and men. Changes in mortality can affect both groups, and the reasons behind those changes are often connected to broader public-health conditions.
For individual women, the most useful takeaway is to focus less on a single life-expectancy number and more on the factors that can support health and independence throughout the years: preventive care, physical activity, nutritious eating, adequate sleep, social connection and appropriate management of health risks.
Frequently Asked Questions
What is the life expectancy of a woman in the United States?
According to final 2024 CDC data, life expectancy at birth for U.S. females was 81.4 years.
How much longer do women live than men in the United States?
In 2024, female life expectancy at birth was 81.4 years compared with 76.5 years for males. The difference was therefore 4.9 years.
Is the life-expectancy gap between women and men shrinking?
Yes. The CDC reported a female–male life-expectancy difference of 5.3 years in 2023 and 4.9 years in 2024. The gap therefore narrowed by 0.4 year in 2024.
Why do women tend to live longer than men?
Researchers consider several explanations, including biological differences, health behaviors, injury and risk exposure, healthcare patterns and social conditions. No single factor completely explains the female longevity advantage.
What is the leading cause of death for women in the United States?
Heart disease remains the leading cause of death for women in the United States. CDC data show that heart disease caused about one in five female deaths in 2023.
Does living longer mean women have better health?
Not necessarily. Life expectancy measures expected length of life, while healthspan focuses on the years lived in relatively good health. A longer lifespan and a healthier lifespan are related but not identical.
