The 5 states with the longest life expectancies, and the 5 with the shortest
- A new study suggests human life expectancy is plateauing.
- In 2022, life expectancy in the US was 77.5 years, but values vary across states.
As anti-aging regimens and longevity treatments continue to gain traction, a new study suggests that humans may have reached a roadblock on their quest for longer lifespans.
On Monday, Nature Aging published an analysis suggesting human life expectancy is plateauing after decades of progress.
Lead study author S. Jay Olshansky, a biostatistician at the University of Illinois, Chicago, told Business Insider's Hilary Brueck, "We've got a lot of people making it out to 85 or 90" but "100 isn't going to happen for most people."
According to a 2022 report by the CDC's National Center for Health Statistics, the average life expectancy in the US was 77.5 years. However, the value varies across states, as factors like environment, diet, exercise, genetics, access to healthcare, and other lifestyle choices contribute to differences.
Using the CDC's National Center for Health Statistics 2021 report — the most recent CDC state data available — here are the five states with the longest life expectancies and the five states with the shortest.
HIGHEST: 5. New Jersey
Life expectancy: 79.0 years
The "Garden State" has the fifth-longest life expectancy in the US, per the CDC data.
According to the Census' 2023 ACS one-year estimates, 92.8% of residents have health insurance compared to 92.1% of Americans nationally. The CDC's Behavioral Risk Factor Surveillance System 2022 also said that adults in New Jersey reported the second-lowest rates of depressive disorders.
The state was named the third-best state to live in by personal-finance company WalletHub, which compared the US states across affordability, economy, education and health, quality of life, and safety. It was also named the third happiest state in the country.
