Life Expectancy Statistics 2026
US life expectancy reached a record high of 79.0 years in 2024, according to the CDC - up from a pandemic low of 76.1 years in 2021. Globally, life expectancy averaged 73.3 years in 2024, but the gap between the longest-lived and shortest-lived nations spans more than 30 years. Regular physical activity is associated with gains of up to 6.9 additional years of life, while sitting for more than three hours a day is linked to losing at least two years. The research is consistent: how much you move, and how much muscle you carry, are among the strongest predictors of how long you live.
Life expectancy is not fixed. The choices people make around exercise, diet, sleep, and body composition shift the number meaningfully - sometimes by a decade or more. That puts longevity firmly in the domain of training, not just medicine.
This post covers 16 key life expectancy statistics drawn from CDC, WHO, and peer-reviewed research. It is for anyone who lifts, trains, or simply wants to understand what the data says about living longer and staying functional for more of those years.
1. US life expectancy hit a record 79.0 years in 2024
79.0 years - the life expectancy at birth for the total US population in 2024 - marks the highest figure ever recorded in the United States, per CDC's National Center for Health Statistics. That is an increase of 0.6 years from 78.4 in 2023.
The gain was driven by falling drug overdose deaths and the decline of COVID-19 as a top cause of death, which dropped off the list of the 10 leading killers entirely. The total number of resident deaths fell by 18,298 compared to 2023.
For a lifter, the baseline matters. The US average is still more than five years behind Japan and other top-ranked nations - and the data on exercise suggest a meaningful share of that gap is behavioural, not genetic.

2. The pandemic wiped 2.7 years off US life expectancy in two years
US life expectancy fell from 78.8 years in 2019 to 76.1 years in 2021 - a drop of 2.7 years across two consecutive years, the largest two-year decline since the early 1920s, according to CDC. COVID-19 accounted for 74% of the 2020 decline and 50% of the 2021 decline.
The collapse was sharpest among American Indian and Alaska Native populations, who lost 6.6 years between 2019 and 2021, reaching a low of 65.2 years. Hispanic Americans lost approximately 3 years, Black Americans approximately 2.9 years.
The bounce-back since 2021 is real but incomplete. The US is still not back to its pre-pandemic trajectory, and the event demonstrated how quickly population-level longevity can reverse when preventable deaths spike.

3. Women outlive men by 4.9 years in the US
US women had a life expectancy of 81.4 years in 2024, compared to 76.5 years for men - a gap of 4.9 years, per CDC's 2024 mortality data. The gap narrowed slightly from 5.3 years in 2023 as male life expectancy recovered faster.
The gender gap reflects higher rates of cardiovascular disease, injury deaths, and drug overdoses among men, combined with lower rates of preventive healthcare use. Men are also significantly less likely to meet the physical activity guidelines that research consistently links to longer life.
The good news for men is that the gap has been shrinking, and the behaviours that extend female longevity - regular activity, consistent sleep, lower sedentary time - are fully accessible.

4. Global life expectancy averaged 73.3 years in 2024
World life expectancy reached 73.3 years in 2024, per Macrotrends data sourced from UN population estimates - up from 71.4 years in 2021 when the pandemic pushed it back to 2012 levels. The WHO noted in May 2024 that COVID-19 eliminated roughly a decade of progress in just two years.
Before the pandemic, global life expectancy had risen from 46.5 years in 1950 to 73.6 years in 2019 - one of the great public-health achievements in history. The post-pandemic recovery has been faster than feared but has not fully restored the prior growth trajectory.
The 73.3-year global average masks massive variation. Monaco leads at 86.5 years. Several low-income nations sit below 60 years. Income, healthcare access, and lifestyle are the main drivers of that spread.

5. Japan's 84.8-year life expectancy is tied to high physical activity culture
Japan's life expectancy of 84.8 years in 2025 places it among the longest-lived nations on earth, per World Population Review data. South Korea (84.4 years) and Hong Kong (85.6 years) are nearby, all sharing cultures with high daily movement and plant-rich diets.
Research published in the International Journal of Environmental Research and Public Health points to low obesity rates, high fish and soy intake, and a public-transport culture that builds walking into daily life as key contributors to Japanese longevity. Walking regularly and using transit are treated as default behaviours, not deliberate exercise.
The contrast with the US - which ranks 62nd globally at 79.5 years - is stark. Countries near the top of the longevity table share structural features that keep people moving throughout the day, not just in dedicated gym sessions.

6. Active people live up to 6.9 years longer than inactive people
Physically active individuals live between 0.43 and 6.9 additional years compared to inactive individuals, according to a systematic review of life-table analyses published in the Journal of Aging Research. The range depends on activity level and the population studied, but the direction is unambiguous.
A 2024 PubMed-indexed life-table analysis confirmed that higher physical activity provides a substantial increase in population life expectancy and that investment in activity-promoting environments directly extends healthy longevity. The benefit does not require elite-level training.
For a gym-goer, even moving from completely sedentary to moderately active captures most of the gain. Studies show the steepest life-expectancy improvement occurs in the first step off the couch, not at the top of the performance scale.

7. Meeting activity guidelines adds 3.4 years of life expectancy
Meeting the minimum guideline of 150 to 299 minutes of brisk walking per week is associated with a gain of 3.4 years of life expectancy, according to a large pooled-cohort analysis cited by the American Heart Association. Going higher - to 450-plus minutes per week - extends the gain to 4.5 years.
The analysis also found that being active at the minimum level reduces all-cause mortality risk by 20 to 21%. Doubling or quadrupling the recommended minimum pushes that mortality reduction to 31%, with no upper threshold of harm identified.
For someone already training three to five days a week, these numbers provide a measurable return on the habit. The data come from hundreds of thousands of participants followed over years, making this one of the most robust life-expectancy datasets available.
8. Strength training alone cuts all-cause mortality risk by 9 to 22%
Regular resistance training is associated with a 9% to 22% lower risk of dying from any cause, even without added cardiovascular exercise, according to research reviewed by Harvard Health. Adding strength training to 2.5 hours of aerobic exercise per week reduces the risk of dying during a study period by 30%.
The data come from a JAMA Network Open study that analysed physical activity in more than 115,000 adults aged 65 and older over a follow-up period averaging nearly eight years. Participants who did both forms of exercise consistently outperformed those who did only one.
Resistance training extends life through multiple pathways - preserving muscle mass, improving insulin sensitivity, lowering cardiovascular risk, and slowing the loss of bone density. It is the component most people skip, but the research suggests it carries independent mortality protection. You can read more in the Strength Training Statistics 2026 breakdown.

9. Sitting more than 3 hours a day cuts life expectancy by 2 years
People who sit for more than three hours per day live approximately two years less than those who sit for fewer than three hours, per an analysis of five large-scale studies following about 2 million people across multiple countries, published in BMJ Open. The effect held regardless of whether the individual met exercise guidelines.
Reducing TV viewing to under two hours per day independently adds approximately 1.4 years. Sitting was also responsible for 3.8% of all-cause mortality - about 433,000 deaths per year - across the 54 countries included in a separate Lancet meta-analysis.
This is the data that separates exercise from movement. An hour-long gym session does not fully cancel eight hours of continuous sitting. Managing total daily sedentary time is a distinct lever from hitting a weekly workout target. For the broader picture on inactivity, see Sedentary Lifestyle Statistics 2026.

10. Sarcopenia nearly doubles the mortality rate compared to muscle-sufficient adults
Older adults with sarcopenia had a mortality rate of 4.8 per 100 person-years over six years, versus 2.1 per 100 person-years for those without sarcopenia - a rate more than double, per a population-based cohort study published in JAMA Network Open. Sarcopenia is the progressive loss of muscle mass and strength with age.
The condition affects a substantial share of older adults: prevalence was 36.5% in one large population-based study. Importantly, the presence of all three sarcopenia criteria (low mass, low strength, low physical performance) was associated with an 87% higher all-cause mortality risk (HR 1.87).
Adults lose approximately 1% of muscle mass per year after their thirties, meaning the trajectory starts decades before it becomes clinically obvious. Resistance training is the most effective intervention to slow that decline and preserve the muscle that appears to be carrying significant longevity value. More data on this process is in Muscle Loss and Aging Statistics 2026.

11. High VO2 max is associated with an 80% reduction in mortality risk
Individuals with elite cardiorespiratory fitness (VO2 max) experienced an 80% reduction in mortality risk compared to the lowest fitness group, in a study of 122,000 patients published in JAMA Network Open. The Copenhagen Male Study found that men in the highest fitness category lived approximately 5 years longer than those in the lowest.
Cardiorespiratory fitness is consistently described as one of the strongest predictors of all-cause mortality - stronger than smoking, diabetes, or hypertension in some analyses. Each 1-MET increase in aerobic fitness correlates with a 13% reduction in all-cause mortality risk.
VO2 max is trainable. Consistent aerobic exercise, especially vigorous-intensity work, raises it meaningfully. For lifters who focus primarily on strength, adding structured cardio does not dilute muscle gains - it adds a separate longevity benefit on top.

12. Short or long sleep both raise mortality risk by 14 to 34%
Sleeping fewer than 7 hours per night raises mortality risk by 14%, and sleeping more than 9 hours raises it by 34%, per a 2025 meta-analysis of 79 cohort studies published in GeroScience. The sweet spot is consistent 7 to 8 hours.
Sleep irregularity compounds the risk independently. A separate study found that people with the most stable sleep-wake patterns had a 30% lower risk of all-cause mortality and a 38% lower risk of cardiometabolic mortality. Poor sleep consistency is a mortality risk even among people who get enough total hours.
For athletes and active people, sleep is the primary recovery window. The mortality data add urgency to what the performance data already suggest: skimping on sleep to train more is counterproductive in every measurable direction.

13. Smoking costs men an average of 13 years of life
Male smokers lose an average of 13 years of potential life compared with never-smokers; female smokers lose 12 years, based on data from the Global Burden of Disease Study 2021, published in PMC in October 2024. Globally, smoking accounted for more than 175 million deaths and nearly 4.3 billion years of life lost from 1990 to 2021.
Tobacco remains the single leading behavioural risk factor for mortality worldwide. If global smoking prevalence steadily declined to 5% by 2050, projections suggest life expectancy in males would increase by approximately one additional year, and 876 million total years of life lost would be avoided.
The smoking numbers put the exercise data in perspective. Regular resistance and aerobic training can add 3 to 7 years. Smoking removes 12 to 13. No training programme fully compensates for a habit that large - but training is still a net positive on top of quitting.

14. Obesity can cut life expectancy by up to 14 years
Severe obesity (BMI 40 or above) is associated with a reduction of up to 14 years of life, based on analyses reviewed in multiple studies including research cited by the American Academy of Sleep Medicine. Standard obesity (BMI 30 to 35) is associated with losing 1 to 6 years.
Young adults aged 20 to 29 with severe obesity face the greatest projected loss - up to 19 fewer healthy life-years. The mechanisms run through heart disease, cancer, and diabetes, which collectively account for the majority of excess deaths in this group.
The physical activity data and the obesity data point in the same direction. Exercise preserves body composition, builds muscle that raises resting metabolic rate, and directly counters the obesity-related mortality risk. The two are not independent variables.
15. Mediterranean diet adherence cuts mortality risk by up to 23%
Women who closely followed a Mediterranean diet were up to 23% less likely to die during a 25-year follow-up period, according to a Harvard-led study of 25,315 women published in JAMA Network Open in May 2024. Reductions in both cancer and cardiovascular mortality were observed.
The diet - high in vegetables, legumes, whole grains, fish, and olive oil, and low in red meat and processed foods - appears to reduce mortality through measurable biological pathways. The researchers identified changes in inflammation markers, lipid profiles, and blood glucose regulation as likely mechanisms.
For people who train consistently, nutrition is the other half of the recovery equation. A diet that reduces systemic inflammation and cardiovascular risk extends both training longevity and overall lifespan - aligning exactly with what the strength and activity data also suggest.

16. Racial disparities put Black Americans 5+ years behind White Americans in life expectancy
The life expectancy gap between Black and White men in the US exceeds five years; among women it exceeds three years, per data reviewed by KFF and multiple peer-reviewed analyses. Black men averaged approximately 69.7 years versus 74.9 years for White men in the years immediately before the pandemic.
COVID-19 widened the gap sharply: Black Americans lost approximately 2.9 years between 2019 and 2020, while White Americans lost 1.4 years. The gap has since started narrowing again, but decades of structural disparities in healthcare access, residential segregation, and occupational exposure to mortality risk keep it large.
Physical inactivity rates are higher in communities with fewer safe spaces to exercise and less access to affordable fitness infrastructure. Addressing the life expectancy gap requires narrowing the activity gap - and that requires lowering the barriers to consistent training.

What the data says about training and longevity
The life expectancy statistics line up around a consistent thesis: the single most modifiable determinant of how long you live is how much you move and how much muscle you carry. The CDC data shows the US is recovering from a historic collapse during the pandemic. The WHO data shows the global average is still below its 2019 level. And the exercise research shows that physically active people live 3 to 7 years longer than inactive people - independent of genetics, income, or country of birth.
What separates the exercise data from the diet and sleep data is the dose-response curve. More activity produces more benefit, with no observed ceiling. Resistance training specifically provides a mortality signal that is independent of cardio - meaning strength work and aerobic work compound each other rather than substituting for one another. The sarcopenia data reinforces this: muscle mass in later life is not just performance-relevant, it is survival-relevant.
The clearest takeaway from these 16 statistics is that consistently tracking and performing both resistance training and aerobic exercise is among the highest-return health investments a person can make.

Frequently Asked Questions
What is the average US life expectancy in 2024?
The average US life expectancy at birth reached 79.0 years in 2024, a record high according to CDC's National Center for Health Statistics. Women averaged 81.4 years and men averaged 76.5 years. The 2024 figure recovered substantially from the pandemic low of 76.1 years in 2021.
How much does exercise increase life expectancy?
Research shows physically active people live between 0.43 and 6.9 years longer than inactive people, depending on activity level. Meeting the minimum guideline of 150 minutes of moderate activity per week is associated with a 3.4-year life expectancy gain. High volumes of both cardio and resistance training produce the greatest longevity benefit.
Does strength training increase lifespan?
Yes. Regular resistance training is associated with a 9 to 22% reduction in all-cause mortality risk, even without added aerobic exercise, per data from a JAMA Network Open study. When combined with 2.5 hours of aerobic exercise per week, the mortality risk reduction reaches 30%. Preserving muscle mass also reduces the risk of sarcopenia, which is independently linked to a nearly doubled mortality rate in older adults.
Which country has the highest life expectancy?
Monaco leads with approximately 86.5 years, followed by Hong Kong (85.6 years), Japan (84.8 years), and South Korea (84.4 years). These nations share features including universal healthcare, low obesity rates, high physical activity levels built into daily routines, and plant-rich diets. The United States ranks 62nd globally at approximately 79.5 years.
