Aging 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.

Why it matters

The old-age dependency ratio among OECD nations is projected to reach 52% by 2060, meaning for every 100 working adults, there will be 52 elderly individuals. This is straining government budgets and traditional family-based caregiving models, leading to isolation and unclaimed deaths among the elderly.

The details

Countries are already experiencing the financial consequences, with Italy's pension system deficit expected to exceed 4% of GDP between 2022-2050 and Japan's social security expenditures reaching a record JPY39.1 trillion (S$313.6 billion) in 2026. Beyond the economic costs, shrinking populations are altering traditional social support systems, as many elderly individuals now live alone with limited family networks. In Seoul, South Korea, over 1,400 funerals were publicly funded in 2024 due to unclaimed bodies, almost 80% involving the elderly.

  • The old-age dependency ratio among OECD nations is projected to reach 52% by 2060.
  • In 2025, Singapore's spending on social development reached S$61.3 billion (US$24.4 billion), nearly doubling from S$31.3 billion in 2015.
  • 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.

An expert from the Institute of Policy Studies (IPS) who notes that declining birth rates and narrower family structures are evolving the nature of caregiving, as caregivers previously had more family members to share the responsibility with.

What they’re saying

“As family sizes shrink, the burden of caregiving is becoming more concentrated, placing greater strain on individuals and increasing the need for state-provided support services.”

The takeaway

The challenges posed by aging populations and shrinking birth rates are global in nature, requiring governments and societies to adapt their social support systems and caregiving models to meet the evolving demographic realities.
