People living in the Southern U.S. generally have lower life expectancies compared to those in other parts of the country, and various experts point to a range of factors that might explain this disparity.
Research indicates that residents in certain Southern states typically face poorer health outcomes and shorter lifespans. Analysts mentioned several potential contributors, such as inadequate healthcare quality, limited access to health insurance, and a prevalence of unhealthy lifestyles.
The Lifespan Research Institute (LRI), which aims to promote advancements in health science, notes that higher rates of chronic diseases, alongside the closure of rural hospitals, may also play a significant role in these lower life expectancies.
One representative from LRI stated, “There’s no one-size-fits-all answer.” In many Southern states, a mix of higher chronic disease rates—like heart problems, diabetes, and certain cancers—and limited access to preventative care, plus socioeconomic factors, is apparent.
It’s worth noting, they continued, that while the issue is complex and layered, it also reflects broader trends in the U.S., with increasing challenges from alcohol-related health issues, opioid dependence, and mental health crises affecting communities already burdened by economic constraints and chronic health issues.
A January 2024 report from The Cornell Healthcare Review highlighted that in states like Mississippi, Louisiana, Alabama, South Carolina, Kentucky, Arkansas, and Tennessee, life expectancy is typically five to ten years shorter than in other regions. The precise reasons for this have yet to be fully understood.
According to estimates released by the National Center for Health Statistics (NCHS), the overall life expectancy for Americans in 2024 was 79.0 years, which shows a slight increase from 2023. Alongside this, the age-adjusted death rate also experienced a decline.
Experts from LRI emphasized that many of the adverse health outcomes observed are preventable, suggesting that improvements in early detection, better management of health risks, and enhanced access to primary care could lead to significant benefits in lifespan and life quality.
Further analysis indicated that states with lower life expectancies are mostly found in the South, while longer life expectancies tend to be associated with areas in the West and Northeast, according to data from USAFacts reported in March 2025.
An April 2025 study illustrated that life expectancy for those born between 1900 and 2000 in many Southern states remained fairly stagnant, with women particularly affected; in contrast, many states in the Northeast and West saw marked improvements.
The Cornell Healthcare Review noted that living in walkable communities can positively influence health, but many residents in the South are reliant on cars for transport.
As of 2025, some of the least walkable cities in the country included Arlington, Texas, Charlotte, North Carolina, and Jacksonville, Florida, according to Radical Storage.
Michael Cannon from the CATO Institute pointed out the complexity of health disparities, noting that factors influencing health, such as income and access to medical care, often intersect. He commented on the cyclical nature of low income and poor health, suggesting that both can exacerbate each other.
He also mentioned that Southerners face significant challenges in improving their health, particularly in terms of healthcare access and financial support due to low incomes.
Cannon summarized the situation in Southern states, suggesting that a combination of low incomes, unhealthy habits, regulatory issues, and limited healthcare access are likely contributors to poorer health outcomes.
A report from Texas A&M University indicated that those in the South suffer from chronic illnesses earlier than their peers elsewhere in the country. Additionally, infectious diseases are also more common in this region, especially in areas like Louisiana and the Carolinas.
A study published in July 2018 in the Journal of the American Heart Association found that individuals who followed a traditional Southern diet had a higher mortality risk compared to those adhering to a Mediterranean-style diet.
Over the past two decades, a report by KFF highlighted a significant gap in death rates, with 1.63 million excess deaths among Black Americans compared to White Americans. As of 2023, a majority of the Black population in the U.S. resided in Southern states, along with smaller percentages in the Midwest, Northeast, and West.
