Women in the United States live to an average age of 81.4 years, based on 2024 data from the CDC. That number has been climbing back after a sharp dip during the pandemic, and it sits about 4.9 years higher than the average for American men. Globally, female life expectancy varies widely depending on country, with the highest figures reaching the late 80s in places like Monaco and Japan.
U.S. Female Life Expectancy in 2024
The most recent CDC data puts female life expectancy at birth in the U.S. at 81.4 years, up from 81.1 in 2023. That 0.3-year increase is part of a broader recovery trend. Overall U.S. life expectancy for both sexes rose to 79.0 years in 2024, a 0.6-year jump from the prior year.
These gains follow a rough stretch. Before the pandemic, U.S. life expectancy at birth was 78.8 years for all adults in 2019. By 2021, it had dropped to 76.1 years. COVID-19 hit men harder than women: the gender gap in life expectancy widened from 4.8 years in 2010 to 5.8 years in 2021. COVID-19 was the single largest contributor to that widening gap, followed by unintentional injuries like drug overdoses, which also disproportionately affected men.
How Race and Ethnicity Shape the Numbers
The 81.4-year average for U.S. women masks significant disparities. Life expectancy varies by more than 15 years depending on racial and ethnic group, and those gaps persist for women specifically. As of 2023, the overall figures by group were:
- Asian Americans: 85.2 years
- Hispanic Americans: 81.3 years
- White Americans: 78.4 years
- Black Americans: 74.0 years
- American Indian and Alaska Native: 70.1 years
Women within each group tend to live roughly five years longer than their male counterparts. But the gap between the longest-lived and shortest-lived groups is striking. An Asian American woman can expect to outlive an American Indian or Alaska Native woman by well over a decade, a disparity driven by differences in healthcare access, poverty rates, chronic disease burden, and environmental exposures.
Where Women Live the Longest
According to 2023 World Bank data, the countries with the highest female life expectancy at birth are Monaco (88.5 years), Hong Kong (88.1 years), Liechtenstein (87.3 years), Japan (87.1 years), and San Marino (87.1 years). Several of these are small, wealthy territories, which makes Japan the most notable example of a large country consistently producing very high female longevity. Japanese women have ranked at or near the top of global life expectancy tables for decades.
Top Causes of Death for Women
Heart disease is the leading killer of women in the United States, responsible for 19.1% of all female deaths in 2021. Cancer follows closely at 17.6%. After that, the list includes COVID-19 (11.1%), stroke (5.7%), and Alzheimer’s disease (5.1%). Heart disease often catches women off guard because it’s frequently framed as a men’s health issue, but it kills nearly one in five women.
Cancer deaths in women are spread across several types, with lung cancer, breast cancer, and colorectal cancer among the most common. Stroke and Alzheimer’s disease both become significantly more likely after age 65, which is why they appear high on the list for women, who on average live long enough to face those age-related conditions at higher rates than men.
Why Women Outlive Men
The female longevity advantage isn’t just a cultural pattern. It has deep biological roots. Research from the Max Planck Institute for Biology of Ageing points to three key mechanisms.
First, women carry two X chromosomes. The X chromosome contains important genes that regulate immune function, among other things. If a gene on one X chromosome is faulty, the second copy can compensate. Men, with only one X and one Y chromosome, have no such backup. A single defective gene on the X chromosome has nowhere to hide.
Second, this chromosomal difference gives women a more robust immune system overall. Gene segments on the X chromosome that influence immune response are effectively doubled in women. This may help explain why men are more vulnerable to certain infections and why COVID-19 killed men at higher rates.
Third, hormones play a role. Testosterone has been linked to both risk-taking behavior and a higher incidence of cardiovascular disease in men. Estrogen, by contrast, appears to offer some cardiovascular protection during a woman’s reproductive years, though that advantage diminishes after menopause. The behavioral component matters too: men are more likely to die from accidents, homicides, and substance use, all of which pull down male life expectancy.
Projected Gains by 2050
Female life expectancy is expected to keep rising. The Global Burden of Disease Study, published in The Lancet, projects that global life expectancy will increase by 4.2 years for women and 4.9 years for men between 2022 and 2050. The slightly larger projected gain for men reflects an expectation that the gender gap will narrow somewhat as public health efforts target the conditions that disproportionately shorten men’s lives.
Still, these projections come with caveats. Rising rates of obesity, diabetes, and other metabolic conditions could slow progress. So could geopolitical instability and climate-related health threats. The pandemic demonstrated how quickly decades of gains can reverse: U.S. life expectancy fell by nearly three years in just two years. Recovery has been steady but not guaranteed to continue at the same pace.
