Hawaii has the highest life expectancy of any U.S. state, consistently topping the rankings for decades. Mississippi sits at the bottom with a life expectancy of 70.9 years, meaning where you live in the United States can account for roughly a decade’s difference in how long you’re expected to live.
Hawaii’s Life Expectancy Lead
Hawaii’s life expectancy hovers around 80 years, placing it well above the national average. The state benefits from a combination of factors: lower obesity rates, higher physical activity levels, relatively low smoking rates, and strong social cohesion among its diverse communities. The mild climate encourages year-round outdoor activity, and the traditional diet in Hawaii leans heavily on fish, fresh vegetables, and rice rather than the processed foods that dominate mainland eating patterns.
Hawaii also has a large Asian American population, and Asian Americans as a demographic group tend to have among the longest life expectancies in the country. This demographic composition contributes to the state’s overall numbers, though it doesn’t fully explain the gap. Even after adjusting for demographics, Hawaii’s health outcomes remain strong.
That said, the state average masks real disparities. While Hawaii leads the nation overall, it has the second-lowest life expectancy for Latino residents at just 77.2 years, compared to 83.8 years for Latino residents in West Virginia. These kinds of gaps show that a state’s top-line number doesn’t tell the whole story for every group living there.
The Top and Bottom Five States
After Hawaii, the states with the longest life expectancies cluster in the Northeast and West. California, Minnesota, Connecticut, and Massachusetts consistently rank near the top, all with life expectancies in the high 70s to low 80s. These states share some common traits: higher median incomes, better access to healthcare, higher rates of health insurance coverage, and lower smoking rates.
At the other end, the five states with the shortest life expectancies are concentrated in the Southeast. Mississippi ranks last at 70.9 years, followed by West Virginia at 71 years and Alabama at 72 years. Louisiana and Arkansas round out the bottom five in most recent data. These states tend to have higher rates of obesity, diabetes, heart disease, and smoking, along with lower rates of health insurance coverage and fewer healthcare providers per capita.
Why the Gap Is So Large
A ten-year difference in life expectancy between states is enormous. To put it in perspective, that gap is larger than the survival benefit of many major medical breakthroughs. Several forces drive it.
Poverty is the single strongest predictor. States with higher poverty rates almost universally have shorter life expectancies. Poverty affects health through multiple channels: limited access to nutritious food, fewer safe places to exercise, higher rates of chronic stress, less access to preventive healthcare, and greater exposure to environmental hazards. Income also shapes health behaviors. Smoking rates, for instance, are roughly twice as high among adults living below the poverty line compared to those with higher incomes.
Healthcare access plays a major role too. States that expanded Medicaid coverage under the Affordable Care Act generally saw improvements in life expectancy, while many of the states that declined expansion are concentrated in the South, where life expectancy is shortest. Rural areas within these states face additional challenges, with hospital closures leaving some communities hours from emergency care.
Obesity rates follow a similar geographic pattern. Mississippi, the state with the lowest life expectancy, also consistently ranks among the highest in adult obesity. Obesity drives heart disease, stroke, type 2 diabetes, and several cancers, all of which shorten life.
Life Expectancy for Black Residents Varies Dramatically
Racial disparities in life expectancy exist in every state, but the size of those disparities varies widely. Hawaii and New Hampshire have the highest life expectancy for Black residents, while Washington, D.C., has the lowest. The reasons are complex, but they involve differences in neighborhood-level poverty, exposure to pollution, access to quality healthcare, and chronic stress related to discrimination.
These within-state gaps are important context. A state with a high overall life expectancy may still have communities where residents die a decade or more earlier than the state average. ZIP code often predicts life expectancy more accurately than state-level data, with neighborhoods just a few miles apart sometimes showing differences of 15 to 20 years.
Recent Trends in U.S. Life Expectancy
The most recent official state-level life expectancy data comes from the CDC’s National Center for Health Statistics, with 2022 figures released in late 2025. U.S. life expectancy overall took a sharp hit during the COVID-19 pandemic, dropping from 78.8 years in 2019 to 76.4 years in 2021 before beginning to recover. The pandemic widened the gap between states, hitting those with lower baseline health harder. Mississippi’s life expectancy, for example, dropped a full year between 2020 and 2021 alone.
Even before the pandemic, though, U.S. life expectancy had been stagnating compared to other wealthy nations. Drug overdose deaths, rising rates of chronic disease, and persistent health inequities all contributed. The geographic pattern of these “deaths of despair” closely mirrors the map of states with the shortest life expectancies, reinforcing that the gap between the healthiest and least healthy states reflects deep structural differences rather than simple lifestyle choices.
