SEOUL, February 9, 2026 — The average life expectancy may be rising globally, but enjoying those extra years in good health is becoming increasingly difficult, particularly for those with fewer resources. A new analysis reveals that healthy life expectancy for South Koreans has dipped below 70 years, a stark reminder that simply living longer isn’t the same as thriving longer.
Healthy Years on the Decline
For decades, humans have equated longevity with a good life. But what if those extra years are spent battling illness? Healthy life expectancy – calculated by subtracting years lived with disease from overall life expectancy – is a more nuanced measure of well-being. According to data from the Ministry of Health and Welfare and the Korea Institute for Health Promotion and Development, the healthy life expectancy of South Koreans decreased for two consecutive years, falling from 70.93 years in 2020 to 69.89 years in 2022. This figure is nearly three years short of the government’s target of 73.3 years, and marks the lowest point since 2013, when it stood at 69.69 years.
The Wealth-Health Divide
The data also reveals a significant disparity based on socioeconomic status. The top 20% of income earners can expect 72.7 years of healthy life, while those in the bottom 20% experience just 64.3 years. That’s an 8.4-year gap, underscoring how deeply intertwined financial stability is with overall health. A shorter period of healthy living inevitably leads to a longer period of illness for individuals.
The Rising Cost of Aging
Illness isn’t just a personal burden; it’s a financial one. The National Health Insurance Corporation’s Health Insurance Research Institute estimates that lifetime health insurance medical expenses per person reached approximately 246.56 million won as of 2023. This includes health insurance contributions, out-of-pocket expenses, and non-reimbursement costs. Interestingly, the age at which medical expenses peak has also shifted, moving from 71 years old in 2004 to 78 years old in 2023, reflecting the extended period of care needed in later life. As longevity increases, so too does the financial strain of prolonged treatment and care.
What Truly Determines Health?
A 2025 Health Awareness Survey Report by the Korea Institute for Health Promotion and Development found that 33.3% of respondents identified ‘income and social level’ as the primary determinant of health. This surpassed factors like access to sports facilities and parks (14.8%), genetic predisposition (12.8%), and personal lifestyle habits (11.5%). The survey revealed that even when people acknowledge the importance of healthy choices, they often cite time and economic constraints as barriers to exercise, nutritious diets, and regular checkups.
The traditional view of longevity needs to evolve. The focus shouldn’t solely be on how long we live, but on delaying the onset of illness and reducing the disparities in healthy life expectancy. Fluctuations in healthy life expectancy have ripple effects, impacting retirement planning, welfare systems, labor markets, and financial projections. While the average desired life expectancy is 83.8 years, with a healthy life expectancy of 78.7 years, policy interventions are crucial to bridge this gap. As the old saying goes, “Play while you’re young, you can’t have fun when you get old.” But perhaps we can create a future where we can enjoy life, and stay healthy, at any age.
