India

India is running the largest aging experiment in human history on a system built for a different century. The country had 149 million people 60 and older in 2022; UNFPA projects 347 million by 2050 — from 10.5% of the population to 20.8%, a 134% jump in the elderly while the overall population grows just 18%. The 80-and-over group, the one most likely to need daily care, grows 279% in the same window (UNFPA India Ageing Report).

The traditional answer was the joint family, and India is distinctive for having backed that tradition with statute. The Maintenance and Welfare of Parents and Senior Citizens Act (2007) makes children and heirs legally obligated to maintain elderly parents who cannot maintain themselves, with fast-track tribunals to enforce it (official text). Few countries anywhere have written filial duty into enforceable law. But statute cannot hold a household together across an ocean: urbanization and emigration are dissolving the joint family faster than anything replaces it.

Into that gap has grown a commercial "silver economy" that NITI Aayog's 2024 senior-care reforms work sized at roughly $7 billion — and its most revealing segment is built for the child who left. Platforms like Emoha (100,000+ users across 120 cities) and Samarth (30,000+ elders in 110+ cities) sell daily check-ins, IoT monitoring, emergency response, and coordination to NRI children managing a parent's care from New Jersey or Dubai; ground reporting describes services that supply, quite literally, "part-time daughters" who visit (ThePrint; YourStory). It is the same long-distance caregiving problem the Caribbean solves informally over WhatsApp — here, productized.

Policy is moving, and one 2024 stroke deserves real credit: the Union Cabinet extended Ayushman Bharat hospital coverage — ₹5 lakh per year, free — to every citizen 70 and older, regardless of income, reaching roughly six crore (60 million) seniors by age rather than means-testing (PM India). That is the boldest simple move on this map since Japan's long-term-care insurance.

The reality check is dementia and money. LASI-DAD, India's first nationally representative dementia study, puts prevalence at 7.4% over 60 — an estimated 8.8 million Indians with dementia, more than the population of Israel — with higher rates among women and in rural areas (Alzheimer's & Dementia). India still has no national dementia plan, a gap The Lancet Psychiatry has called out directly (Lancet Psychiatry). And UNFPA's hardest numbers are financial: 40% of India's elderly sit in the poorest wealth quintile, and about one in five has no income at all. The startups serve the families who can pay. The law obligates the families who can't. Between them sits the largest caregiving population on Earth, mostly uncounted and entirely unpaid — which is why India belongs on this map, and why what gets built for its families matters everywhere.
