These U.S. States Have the Shortest Life Expectancies, New Data Shows
New health data reveals the U.S. states where people have the shortest average lifespans. Mississippi ranks last at 73.9 years, while Southern states dominate the list. Explore the numbers, health trends, and factors shaping America’s life expectancy gap.
Where Americans Live May Influence How Long They Live
The United States has made progress in recovering from the life expectancy decline seen during the COVID-19 pandemic, but new data shows that where Americans live can still have a major impact on how long they are expected to live.
While the national average life expectancy has climbed back to about 79 years, residents in some states are living several years less on average. The latest ranking based on County Health Rankings data shows a noticeable divide between states with the shortest lifespans and the rest of the country.
The difference between the highest and lowest states in the ranking represents a gap of nearly 5 years of life expectancy, which equals roughly 1,800 fewer days of life on average. Mississippi recorded the lowest figure at 73.9 years, while Alaska had the highest among the 25 lowest-ranked states at 78.6 years.
The numbers reveal a broader public health story involving chronic diseases, access to medical care, economic conditions, rural challenges, and opportunities available to residents throughout their lives.
Mississippi Ranks No. 1 for the Shortest Life Expectancy at 73.9 Years
Mississippi ranks at the bottom of the list, with an average life expectancy of 73.9 years, the lowest among the 25 states examined.
The state has approximately 496,945 residents aged 65 and older, representing about 16.8% of the population. However, life expectancy is not only determined by the health of older adults. The figure includes deaths across all age groups, from infants to working-age adults and seniors.
Mississippi’s ranking reflects several long-term health challenges that public health researchers often examine, including higher rates of chronic illnesses such as heart disease and diabetes, limited access to preventive care in some communities, and economic barriers that can influence health decisions.
The number does not mean every Mississippi resident will live only until their early 70s. Instead, it represents a statewide average shaped by millions of individual experiences.
West Virginia Has the Second-Shortest Lifespan in America
West Virginia ranks second, with an average life expectancy of 74.3 years.
The state has one of the oldest populations in the nation, with seniors making up approximately 20.7% of residents, or about 368,775 people aged 65 and older.
West Virginia’s health challenges are closely connected to its geography and demographics. Many communities are rural, meaning residents may have to travel longer distances for specialty care, emergency treatment, or routine medical appointments.
The state has also faced significant challenges related to chronic disease, economic changes, and access to health services. These factors often overlap, creating conditions that influence health outcomes over decades.
Alabama Ranks Third With Life Expectancy Below 75 Years
Alabama ranks third-lowest, with residents having an average life expectancy of 74.8 years.
The state has nearly 886,000 seniors, making up about 17.6% of its population. Alabama’s position highlights a common pattern among states with shorter lifespans: health outcomes are influenced by multiple factors rather than one single cause.
Chronic diseases, healthcare access, lifestyle-related risks, and differences between urban and rural communities all contribute to population health trends.
The gap between Alabama’s average lifespan and the national figure of about 79 years represents more than 4 years of difference, showing how significant state-level health disparities can become over time.
Kentucky and Louisiana Complete the Bottom Five
Kentucky ranks fourth with an average life expectancy of 75.1 years, while Louisiana follows closely at 75.2 years.
Kentucky has approximately 768,416 senior residents, representing 17% of the state population, while Louisiana has about 766,330 seniors, accounting for 16.6% of residents.
Both states demonstrate how life expectancy is shaped by conditions that begin long before old age. Factors such as healthcare access, economic stability, education, housing conditions, and preventable health risks can influence whether people reach older ages.
Louisiana also ranked lowest among the states in the accompanying senior-health measurement used in the original dataset, showing continued pressure on healthcare systems serving older residents.
Southern States Dominate the Lowest Life Expectancy Ranking
One of the strongest patterns in the data is the concentration of low life expectancy in the South.
Nine of the 10 states with the shortest average lifespans are Southern states: Mississippi, West Virginia, Alabama, Kentucky, Louisiana, Tennessee, Arkansas, Oklahoma, and South Carolina. Indiana is the only state outside that regional group among the bottom 10.
The pattern does not mean geography alone determines lifespan. Instead, many Southern states share similar challenges, including higher levels of chronic disease, rural healthcare shortages, transportation barriers, and economic disadvantages in some communities.
Public health experts often describe these influences as social determinants of health, meaning the everyday conditions that affect people’s ability to stay healthy.
Shorter Life Expectancy Is Often Linked to Deaths Before Old Age
Life expectancy rankings are not simply about how long senior citizens live.
A state’s average lifespan can decrease when more people die at younger ages from causes such as heart disease, cancer, drug overdoses, traffic accidents, workplace injuries, or other preventable conditions.
For example, losing someone at age 45 has a much greater impact on life expectancy calculations than losing someone at age 90.
That is why improving life expectancy requires protecting people throughout every stage of life, from childhood and adulthood to retirement.
Oklahoma and Arkansas Remain Below 76 Years
Oklahoma and Arkansas both recorded an average life expectancy of 75.5 years.
Arkansas ranked seventh-lowest, while Oklahoma ranked eighth. Both states have significant rural populations where access to healthcare can be more challenging.
Residents in rural communities may face longer travel distances to hospitals, fewer specialists, and limited access to preventive services.
The CDC has reported that rural Americans experience higher death rates from several major causes compared with people living in urban areas. The difference is often connected to healthcare access, transportation, economic conditions, and health behaviors.
Tennessee, South Carolina, and Indiana Round Out the Bottom 10
Tennessee recorded an average lifespan of 75.3 years, placing it sixth-lowest in the ranking.
South Carolina followed with an average life expectancy of 76.4 years, while Indiana ranked 10th at 76.5 years.
These states show that shorter life expectancy is not limited to one region. Although Southern states dominate the list, Indiana demonstrates that communities outside the South can also experience challenges linked to chronic disease, healthcare access, and economic changes.
Each state faces a different combination of factors that shape its health outcomes.
Some States Have Strong Senior Health Scores but Lower Overall Lifespans
One of the more surprising findings is that some states with stronger senior-health rankings still appear among those with shorter overall life expectancy.
Missouri ranked relatively high in senior health but had an average lifespan of 76.6 years. Ohio ranked well in senior health while recording a life expectancy of 76.5 years. Pennsylvania also performed strongly in senior health rankings but remained on the list with an average lifespan of 78 years.
The reason is simple: senior health and life expectancy measure different things.
A state can provide quality services for older adults while still experiencing higher rates of premature deaths among younger residents.
Rural Communities Face Unique Health Challenges
Many states near the bottom of the ranking contain large rural populations, and geography can influence access to healthcare.
In some areas, residents may need to travel dozens of miles for specialist appointments, emergency treatment, or advanced medical services.
This matters because early treatment can save lives. A person experiencing a heart attack, stroke, or serious injury may have better outcomes when emergency care is nearby.
Improving rural health often requires expanding local clinics, supporting healthcare workers, improving transportation, and increasing access to preventive services.
Native American Health Data Reveals Additional Gaps
Researchers have also identified concerns about historical undercounting of some racial and ethnic groups in mortality data.
A 2025 study published in the Journal of the American Medical Association found that American Indian and Alaska Native life expectancy may have been significantly underestimated in previous records because racial identity can be incorrectly recorded on death certificates.
The study estimated life expectancy among American Indian and Alaska Native populations at approximately 72.7 years, revealing a major gap compared with the broader U.S. population.
The issue is especially important in states with larger Native populations, including Alaska, Montana, South Dakota, Oklahoma, and New Mexico.
America’s Life Expectancy Is Improving, But the Gap Remains
The national picture has improved.
In 2024, U.S. life expectancy reached approximately 79 years, increasing by about 0.6 years from the previous year.
However, national progress does not mean every state or community is improving equally.
A person living near major medical centers with strong transportation networks may experience a very different healthcare environment compared with someone living in a rural area with fewer services.
The national average tells one story. Local communities often tell another.
What Could Help States Increase Life Expectancy?
Improving lifespan requires more than expanding hospitals. It involves creating healthier conditions before people become seriously ill.
Preventive healthcare remains one of the most effective tools. Regular screenings for cancer, diabetes, high blood pressure, and heart disease can identify problems earlier and improve outcomes.
Expanding healthcare access in rural communities can also make a major difference. More primary-care providers, better emergency services, telehealth options, and transportation support can help residents receive care sooner.
Reducing smoking, improving treatment for substance-use disorders, increasing access to healthy foods, and strengthening education and economic opportunities are also important parts of improving population health.
Longer lives are usually the result of many systems working together.
The Bigger Picture Behind America’s Life Expectancy Divide
The data shows that life expectancy is about more than a number. Behind every statistic are families, communities, and millions of individual experiences.
Mississippi’s 73.9-year average and Alaska’s 78.6-year average represent a difference of nearly 5 years, but the reasons behind that gap are complex.
Where people live can influence their access to healthcare, education, income opportunities, transportation, and healthy environments.
The path toward longer lives will require more than treating disease after it appears. It will depend on building communities where people have the opportunity to stay healthier from childhood through old age.
