In December 2024, the share of South Koreans aged 65 and older crossed the 20% threshold for the first time, officially making the country a “super-aged society.” By August 2026, that figure had climbed to 22.1%. While the label may sound alarming, population aging is not inherently a problem—it reflects progress in reducing premature deaths and extending lifespans. The real issue is the speed of the transition and whether society can adapt in time.
South Korea moved from an aging society (7%–13% over 64) to a super-aged one in roughly 24 years. That is far faster than Japan, which took 35 years, and leaves Seoul with little breathing room to overhaul its pension, healthcare, and labor systems. By 2060, projections suggest that about 41% of South Koreans will be 65 or older, making it the oldest country in the world.
Demographic shift and family change
The demographic transformation is visible in the country's age structure. In the 1990s, the largest cohorts were those aged 15 to 34. Today, those same people are past 45, and the oldest have already hit South Korea's statutory retirement age of 60. Meanwhile, the share of people under 30 is shrinking rapidly.
This aging is tied to a broader shift in fertility and family life. As individual autonomy has grown, South Korea has seen sustained low fertility, later marriage and parenthood, and more diverse family arrangements. The country now has one of the lowest fertility rates on the planet, a trend that shows no sign of reversing.
Economic strain and pension shortfalls
South Korea's retirement system relies on the National Pension Service, funded by contributions from workers, employers, and the self-employed, plus a separate tax-funded Basic Pension for lower-income seniors. But the national pension fund is projected to be depleted by 2054 unless reforms take hold. Many older adults have incomplete contribution histories and receive only modest benefits, leaving those born before 1950 particularly vulnerable.
According to the latest OECD data, South Korea has the highest old-age income poverty rate among the 38 member countries: 39.7% of people aged 66 and older live on less than half the national median disposable income, compared with the OECD average of 14.8%. Despite repeated policy attempts, economic insecurity persists.
Many older South Koreans are asset-rich but cash-poor—over 80% of their assets are tied up in real estate, with only 12.4% in savings. As a result, they often combine the Basic Pension with reverse mortgages to convert property into income.
Work and retirement
Because pensions fall short, South Korea has one of the highest employment rates among older adults in the OECD. Men typically leave their longest-held job at around age 51 but continue working until about 72, often in lower-paying “second careers.” The government is debating whether to raise the statutory retirement age from 60 to 65, which would let workers stay in their primary jobs longer and narrow the gap between retirement and pension eligibility.
However, raising the retirement age is not a silver bullet. It could ease financial pressure for older workers but may also block upward mobility for younger employees if senior positions remain occupied longer. A 2025 pension reform will gradually raise the contribution rate from 9% to 13% by 2033 and set the target replacement rate at 43%.
Healthcare and social care
Healthcare is another major challenge. In 2008, South Korea introduced long-term care insurance, covering home care, nursing, rehabilitation, daycare, assistive devices, and residential care for those with physical or cognitive needs. The program is financed through National Health Insurance, government funds, and user copays. Eligibility is not income-based, though lower-income beneficiaries pay reduced or no copays.
Demand for these services is surging as the population ages, putting pressure on both the system and its workforce. Beyond physical health, South Korea is also addressing loneliness and mental health among the elderly, recognizing that social isolation is a growing concern.
South Korea's experience is not just a national story—it is a regional one. Other Asian societies, including China and Japan, are watching closely. As Seoul rethinks its alliances and deepens ties with Indonesia, the demographic clock is ticking. The choices South Korea makes now will offer a blueprint—or a warning—for the rest of the Indo-Pacific.
