Seoul: Korea is projected to have the world's oldest population by 2060, surpassing Japan, presenting a significant challenge to its pension, healthcare, labor, and fiscal systems. According to Yonhap News Agency, a 2025 report from the U.S. Census Bureau indicates that the share of Korea's population aged 65 and over is expected to rise from 20.3 percent in the previous year to 41 percent in 2060, the highest globally. Additionally, the proportion of those aged 80 and above is anticipated to nearly quadruple from 4.8 percent to 18.3 percent.

The old-age dependency ratio is projected to escalate from 29.5 elderly individuals for every 100 working-age adults to 81.6, meaning fewer than two workers will support each older person. This demographic shift threatens economic growth as the era of a large working-age population providing a demographic dividend ends, ushering in a period of demographic drag characterized by a shrinking labor force, rising dependency, and growing demand for public services.

Korea's already-high elderly poverty rate exacerbates the issue. In 2020, the country had the highest old-age poverty rate among OECD members at 40.5 percent. Factors such as the late introduction of the national pension system, limited benefit coverage, inadequate replacement rates, and a seniority-based wage structure encouraging early retirement contribute to this situation. Longer life expectancy also increases the demand for medical and long-term care, with government estimates suggesting that more than one in 10 Koreans aged 65 or older could have dementia by 2040.

Successive governments have invested heavily in addressing low birthrates and population aging through cash allowances, expanded parental leave, and housing support for young couples. However, these measures have done little to change structural conditions discouraging marriage and childbirth, such as high housing costs, intense educational competition, expensive private tutoring, and insecure employment.

While a recent increase in the total fertility rate is promising, it should not lead to complacency. Korea must simultaneously remove structural barriers to having children and prepare for an aging society. This involves shifting from subsidies to structural reform, providing affordable housing, stable jobs, and realistic ways to balance work and family life. Education policy must address intense competition for university credentials and private tutoring burdens, while family policy should support diverse family arrangements, including unmarried couples.

Korea must also optimize its workforce by raising the effective retirement age, expanding post-retirement employment, reforming seniority-based pay, and increasing women's labor force participation. Managed immigration will become increasingly crucial.

Pension reform is urgent, as is redesigning health, long-term care, and other social programs to accommodate a super-aged society. While raising the age threshold for some senior benefits may be considered as life expectancy rises, such changes should not shift costs onto the already vulnerable elderly population. Reform must balance fiscal sustainability with adequate protection.

Ultimately, demographic policy requires political courage and continuity, as population decline is a long-term challenge that cannot be managed within electoral cycles. Korea's delayed response to declining fertility should serve as a lesson: delay is a costly policy choice. Korea cannot stop demographic aging but can determine whether the transition becomes a national crisis or a manageable transformation through coordinated reforms in pensions, taxation, education, housing, labor, and welfare, supported by a strong political consensus.
