The global average age of death is about 71.4 years, based on the most recent World Health Organization estimates from 2021. In the United States, that number is higher: 79.0 years as of 2024. But these figures shift dramatically depending on sex, geography, and the specific causes of death most common in a given population.
Global vs. U.S. Life Expectancy
The 71.4-year global average masks enormous variation between countries. Among high-income nations, Switzerland leads at 84.2 years, followed closely by Japan at 84.1 and Sweden at 83.8. Australia and France both come in around 83.0. The United States, despite spending more on healthcare than any comparable country, sits at 79.0, the lowest among wealthy nations. Germany (81.2), the United Kingdom (81.3), and the Netherlands (81.9) all outpace the U.S. by two or more years.
The gap between the richest and poorest countries is far wider. Low-income nations in sub-Saharan Africa often have life expectancies in the mid-50s to low 60s, driven largely by infectious disease, maternal mortality, and limited healthcare access.
Women Live Nearly Five Years Longer
In the United States, women live to an average of 81.4 years while men average 76.5, a gap of 4.9 years. This pattern holds across virtually every country in the world. The reasons are partly biological: estrogen appears to offer some cardiovascular protection during reproductive years, and having two X chromosomes provides a genetic backup that may buffer against certain inherited conditions. But behavior plays a large role too. Men historically have higher rates of smoking, heavy drinking, occupational hazards, and deaths from accidents and violence.
The gap has actually narrowed over the past few decades. In 1950, U.S. women outlived men by about 5.5 years (71.1 vs. 65.6). As smoking rates among men declined and workplace safety improved, their life expectancy gained ground.
How Much Life Expectancy Has Grown
The increase over the past century is staggering. In 1950, the average American man could expect to live to 65.6 and the average woman to 71.1. By 2000, those numbers had climbed to 73.7 and 79.4. Today they stand at 76.5 and 81.4. That’s roughly a decade of additional life gained in 74 years.
Most of the early gains came from reducing infant and childhood mortality. Vaccines, antibiotics, clean water, and better nutrition meant far more people survived to adulthood. More recent gains have come from treating the diseases of aging, particularly heart disease and stroke, where improved medications and surgical techniques have added years to the lives of older adults.
The Pandemic Set the Clock Back
Between 2019 and 2021, global life expectancy fell by 1.8 years, the largest drop in recent history. That single decline erased roughly a decade of progress, pushing global averages back to 2012 levels. COVID-19 became the second leading cause of death worldwide in 2021, directly responsible for 8.8 million deaths that year alone.
Recovery has been uneven. In the U.S., life expectancy has rebounded from its pandemic low of around 76.4 in 2021 to 79.0 in 2024, a gain of 0.6 years over 2023 alone. But the WHO has warned that the broader trajectory of global health improvement was already slowing before the pandemic, and the recovery since has been sluggish.
What People Actually Die From
Heart disease is the world’s leading killer, responsible for 13% of all deaths globally. Stroke ranks third at about 10%. Together, cardiovascular diseases account for more deaths than any other category. These are largely diseases of aging and lifestyle: high blood pressure, high cholesterol, smoking, diabetes, and physical inactivity all increase risk substantially.
Lung cancer deaths have risen from 1.2 million in 2000 to 1.9 million in 2021, making it the sixth leading cause of death. Alzheimer’s disease and other dementias rank seventh, reflecting both aging populations and better diagnosis. Diabetes deaths have surged by 95% since 2000, and kidney disease has jumped from the nineteenth leading cause of death to the ninth over the same period. Lower respiratory infections remain the deadliest communicable disease outside of COVID-19.
In total, the top 10 causes of death accounted for 39 million of the 68 million deaths worldwide in 2021. Seven of those ten are noncommunicable diseases, meaning they develop over time rather than being caught from another person.
Life Expectancy After 65
The “average age of death” figure describes life expectancy at birth, which is pulled down by every death that occurs in childhood, young adulthood, and middle age. If you’ve already reached 65, your statistical outlook is considerably better. A 65-year-old man in the U.S. can expect to live an additional 17.5 years, to about 82.5. A 65-year-old woman can expect roughly 20 more years, reaching about 85.
This distinction matters for practical planning. If you’re approaching retirement age and wondering how long your savings need to last, the “average age of death” headline number significantly underestimates your likely lifespan. The longer you’ve already lived, the longer you’re statistically expected to keep living.
Healthy Years vs. Total Years
Living longer doesn’t necessarily mean living well for all of those years. The WHO tracks “healthy life expectancy,” which measures how many years a person can expect to live in full health before disease or disability significantly limits daily function. Globally, that number is 61.9 years, nearly a decade less than the total life expectancy of 71.4. The gap represents years spent living with chronic pain, reduced mobility, cognitive decline, or dependence on others for basic activities.
Healthy life expectancy has improved, rising from 58.1 years in 2000 to 61.9 in 2021. But the roughly 9.5-year gap between total lifespan and healthy lifespan has remained stubbornly consistent. In practical terms, this means the average person worldwide spends the last decade of life dealing with meaningful health limitations. The factors that widen or narrow that gap are largely the same ones that affect total lifespan: physical activity, diet, smoking, alcohol use, access to preventive care, and management of chronic conditions like diabetes and high blood pressure.
