South Korea Added 7.94 Years of Life Expectancy Since 2000 as US Longevity Slipped
2 articles · Updated · CNN · May 16
South Korea’s life expectancy rose 7.94 years from 2000 to 2021, far outpacing the United States and prompting fresh attention to habits Americans could adopt.
School lunches built around vegetables, fruit and fermented foods illustrate one difference: a 2023 CDC report found nearly half of US children ages 1 to 5 do not eat a vegetable daily.
Activity also stands out. Regular exercise is linked to up to a 40% lower risk of early death, while loneliness and social isolation were tied to a 32% higher risk in a 2023 study.
Healthcare is another divide: South Koreans commonly seek affordable care early, while US doctors are paid far more for procedures than for prevention, experts said.
The practical takeaway is incremental prevention—more plants, exercise and strength training, sleep, stress control, vaccines and screenings, and less tobacco, vaping and alcohol.

Overview
The report highlights the growing gap in life expectancy between South Korea and the United States, with South Korea now significantly ahead. As of 2024, South Korea’s life expectancy at birth is about 83.6 years, while the U.S. is at 78.9 years. This widening difference is the result of South Korea’s decades-long investment in preventive healthcare and effective public health strategies. The report also notes that South Korea’s longevity gains are not only national but also include a narrowing gender gap, showing broad improvements across the population. In contrast, the U.S. faces stagnation and decline in life expectancy.
