South Korea, which faces one of the world's most acute demographic crises, has begun deploying artificial intelligence to make welfare check calls to elderly people living alone and to assist in efforts to combat dementia, reflecting the country's increasingly urgent need to stretch its care resources.
South Korea is turning to artificial intelligence to help manage the mounting pressures of an ageing population, deploying AI systems to conduct routine check-in calls on elderly residents who live alone and to support efforts aimed at detecting and slowing the progression of dementia.
The country holds the distinction of being the world's fastest-ageing society, a demographic reality that has strained public services and forced policymakers to seek technological solutions where human caregivers are in short supply.
AI-powered telephone systems have been introduced in several municipalities to contact isolated elderly residents on a regular basis, checking on their health and wellbeing. These automated calls serve as an early-warning mechanism, flagging concerns to human social workers when a resident fails to respond or indicates distress.
Beyond welfare checks, the technology is also being applied in the fight against dementia — a condition that disproportionately affects older populations and places significant burdens on both families and the healthcare system. AI tools are being used to screen for early cognitive decline and to provide cognitive engagement exercises intended to help slow deterioration.
South Korea's approach reflects a broader global debate about the appropriate role of technology in elder care. Proponents argue that AI can extend the reach of an overstretched care workforce, providing consistent contact for seniors who might otherwise go days without meaningful interaction. Critics, however, caution that automated systems cannot replace the empathy and nuanced judgement of human carers, and raise concerns about privacy, data security, and the risk of reducing human connection for a population already vulnerable to loneliness.
The initiative comes as South Korea's fertility rate has fallen to record lows, accelerating the demographic imbalance between older and younger generations. With fewer working-age citizens available to support an expanding elderly cohort, government and local authorities have increasingly looked to technology to fill the gap.
Whether AI-driven elder care proves to be a sustainable and humane model — or a stopgap measure that sidesteps deeper systemic issues — remains an open question both within South Korea and for other nations watching its experiment closely.
Analysis
Why This Matters
- South Korea's model may serve as a blueprint for other rapidly ageing nations, including Japan, Germany, and Italy, all of which face similar demographic pressures in the coming decades.
- The programme raises fundamental questions about digital equity — elderly residents who are less comfortable with technology, or who live in areas with poor connectivity, may be left behind.
- Governments worldwide are watching to see whether AI elder care can deliver measurable improvements in health outcomes and reduce costly emergency interventions.
Background
South Korea's fertility rate fell to a record low of approximately 0.72 in 2023, far below the 2.1 replacement level, making it the lowest among OECD nations. The country's population is ageing faster than almost any other in the world, driven by longer life expectancy and declining birth rates that have persisted for decades.
The government has spent years attempting to reverse the fertility decline through financial incentives, parental leave expansion, and housing subsidies — with limited success. Attention has increasingly shifted toward managing the consequences of an older society rather than reversing its cause.
South Korea has a history of early and ambitious technology adoption, and its telecommunications infrastructure ranks among the world's most advanced. This has made it a natural testing ground for AI-assisted public services, with elder care emerging as one of the most pressing applications.
Key Perspectives
Government and local authorities: View AI as a cost-effective way to maintain regular contact with isolated elderly residents and to triage care needs efficiently, allowing human workers to focus on higher-priority interventions.
Technology advocates: Argue that consistent, low-cost AI check-ins can meaningfully reduce social isolation and enable earlier detection of health deterioration, potentially preventing costly hospitalisations.
Critics and care professionals: Warn that AI calls cannot substitute for genuine human relationships, and express concern that the normalisation of automated care may allow governments to underfund human social services. Privacy advocates also flag risks around the collection and storage of sensitive health data.
What to Watch
- Longitudinal health outcome data from municipalities using AI check-in systems, to determine whether the technology actually reduces emergency incidents or hospitalisations among elderly users.
- Whether South Korea expands the programme nationally and integrates AI more deeply into its formal healthcare system.
- How other OECD nations with ageing populations respond — adoption or rejection of a similar model could signal whether AI elder care becomes a global norm.
