South Korea's Rapid Demographic Transition
South Korea's transition into a 'super-aged' society is one of the fastest in the world. The nation's population aged 65 and over has been growing consistently for years. For context, in 2008, this age group accounted for just over 10% of the total population. By July 2024, the number of individuals aged 65 and above surpassed 10 million for the first time. A subsequent report from December 2024 confirmed that the proportion of the population in this age bracket exceeded 20%, officially classifying South Korea as a 'super-aged' society. This milestone highlights a profound demographic shift with far-reaching consequences for the country's economy, healthcare system, and social structure.
The Driving Forces Behind the Aging Population
The dramatic increase in South Korea's elderly population is the result of a convergence of factors. The two primary drivers are a historically low fertility rate and a high life expectancy, a trend also seen in other developed nations but magnified in its speed in South Korea.
Low Fertility Rates
South Korea holds the unenviable record of having one of the world's lowest fertility rates. The number of births has been in steady decline for decades, with the total fertility rate dropping to record lows, far below the replacement level of 2.1.
This trend is influenced by several factors, including:
- High child-rearing costs and educational expenses.
- Soaring property prices that make housing unaffordable for many young couples.
- A demanding work culture that leaves little room for work-life balance, particularly for women.
- Delayed marriage and an increasing number of single-person households.
High Life Expectancy
Simultaneously, South Korea has achieved one of the highest life expectancies globally. Advances in healthcare, improved living standards, and economic development have all contributed to people living longer. For example, studies have projected that women in South Korea could be the first to have an average life expectancy above 90 years by 2030. While a longer lifespan is a positive development, when combined with a shrinking younger population, it puts a significant strain on social support systems.
Economic and Social Consequences
The rapid aging of South Korea's population presents a complex set of challenges for the nation.
Labor Force Contraction
As the number of working-age people declines and the proportion of retirees increases, South Korea faces a shrinking labor force and a growing dependency ratio. This places a substantial economic and financial burden on the younger, working generation, who must support an increasingly large elderly population. This shift also impacts national productivity and economic growth.
Strain on Welfare and Pensions
The national pension and healthcare systems are coming under immense pressure. With fewer workers contributing and more retirees drawing benefits, official estimates suggest the national pension fund could be depleted in the coming decades if the current system is not reformed. This financial strain is exacerbated by the fact that many seniors face financial hardship due to involuntary early retirement.
Challenges in Elderly Care
The healthcare system is struggling to adapt to the needs of the aging demographic. There is an urgent need for reforms to address:
- The shortage of comprehensive home healthcare programs.
- The high burden of caregiving that often falls on family members, especially women.
- The lack of a robust primary care and geriatric medicine framework.
- The prevalence of multimorbidity and polypharmacy in the older population.
Regional Differences and Government Responses
Demographic trends are not uniform across South Korea. While urban centers like Sejong have a younger population, predominantly rural and agricultural regions like South Jeolla province have a much higher concentration of elderly residents.
The government has recognized the severity of this demographic crisis. Responses have included:
- Pronatalist policies: A range of measures aimed at boosting the birth rate by providing financial support for parents and children.
- Extended working age: Discussions and policies are in place to extend the retirement age to cope with the shrinking workforce.
- Integrated care policies: Efforts to establish community-integrated care to better meet the needs of the elderly.
- Technological innovation: Leveraging advanced technology for U-health and elderly-friendly products.
Population Trends Comparison
| Indicator | South Korea (2024/2025) | Japan (for context) | OECD Average (for context) |
|---|---|---|---|
| Elderly Population (>65) | >10 million (~20%) | Became 'super-aged' earlier (2006) | N/A - varies widely |
| Transition Speed (Aging to Aged) | 18 years | 24 years | Generally much slower |
| Total Fertility Rate | Extremely low (e.g., 0.72 in 2023) | Also low, but historically higher | Varies, but SK far below average |
| Working-Age Population | Rapidly shrinking | Shrinking for decades | Varies, often aided by immigration |
| Labor Force Participation (>60) | Strong desire to work longer | Many work past retirement age | Varies by country |
The Path Forward
The path forward for South Korea involves a comprehensive and multi-pronged approach that extends beyond simple policy changes. Addressing the cultural and economic barriers to raising children is paramount, as is reforming the social welfare system to ensure a dignified retirement for the growing senior population.
While the aging population poses significant burdens, it also presents opportunities for innovation in areas like AgeTech and elderly-friendly industries. The collective knowledge and experience of older generations can be harnessed to benefit society, provided there are effective policies to support active aging and reduce age-based workplace discrimination. A recent report from Human Rights Watch highlighted the issue of age-based employment policies in South Korea. Tackling such discrimination is crucial for creating a truly inclusive society.

In conclusion, understanding how many people in South Korea are 65 and older is not merely a statistical exercise. It's a critical look at a nation facing one of the most pressing demographic challenges of our time. The figures reveal a society in a moment of profound change, and how it chooses to respond will define its future for decades to come.
