Ageing populations are creating significant financial and social strains across the globe, as the number of elderly citizens rises relative to the working-age population. This demographic shift is impacting nations differently, but the core challenges – supporting a growing elderly population and maintaining adequate social structures – are becoming increasingly common.
Financial Burdens on the Rise
The old-age dependency ratio among OECD nations is projected to reach 52 percent by 2060. This means that for every 100 working adults, there will be 52 elderly individuals, a substantial increase from approximately 33 percent in 2025.
Countries are already experiencing the financial consequences. In Italy, the European Commission anticipates a pension system deficit exceeding 4 percent of GDP between 2022 and 2050. Japan’s social security expenditures are also climbing, reaching a record JPY39.1 trillion (S$313.6 billion) in its 2026 budget – representing about one-third of all government spending.
Evolving Social Support Networks
Beyond the economic costs, shrinking populations are altering traditional social support systems. Previous generations often relied on larger families for care and companionship, but today, many elderly individuals live alone with limited familial networks.
This isolation is linked to negative health outcomes and, tragically, can lead to elderly individuals dying undetected. In South Korea, 3 million single-person households were comprised of individuals aged 60 and above in 2024 and projections indicate that by 2049, over half of all single-person households will be aged 65 or older.
The consequences of this trend are starkly illustrated by the situation in Seoul, South Korea, where over 1,400 funerals were publicly funded in 2024 due to unclaimed bodies – a significant increase from 382 cases in 2018. Almost eight in ten of these unclaimed deaths involved elderly individuals.
Dr. Kalpana Vignehsa, from the Institute of Policy Studies (IPS), notes that declining birth rates and narrower family structures are evolving the nature of caregiving. She explains that even as caregivers have always faced strain, they previously had more family members to share the responsibility with.
Frequently Asked Questions
What is the old-age dependency ratio?
The old-age dependency ratio is the number of individuals aged 65 or older per 100 people of working age, defined as those aged between 20 to 64 years old.
What is happening with unclaimed bodies in Seoul?
In 2024, more than 1,400 funerals in Seoul had to be funded by the public as the bodies were unclaimed, a significant increase from 382 such cases in 2018. Almost eight in 10 of these deaths involved the elderly.
What does Dr. Vignehsa say about the future of caregiving?
Dr. Vignehsa states that as family structures become narrower, the burden of caregiving will evolve, and greater societal support is needed to facilitate those who want to have children be the best parents they can be.
As more women pursue careers and both parents work, will societies adapt to provide the necessary support for both the elderly and families?
