Developing countries are growing old before they are growing rich. Their societies are aging quickly — but without the pension systems and personal savings that sustain older people in most developed countries.
The Arithmetic of Getting Old First
One in six Thais is over the age of 65, the result of a baby bust that began in the 1970s. Within about a decade, the country’s fertility rate fell from nearly six children per woman to just over two. Today Thailand’s fertility rate is 0.9, compared with 1.6 in the U.S. and less than half the level needed to keep a population stable. Average life expectancy meanwhile jumped from 51 years in 1960 to 77 now — just two years below the U.S.
The United Nations calls a country an “aging society” once at least 7% of the population is over 65, and an “aged society” once that cohort has doubled to 14%. The U.S. crossed the first line in the early 1940s and took about 70 years to cross the second. Thailand became an aging society in 2004 and an aged society just 18 years later. Both countries are projected to become “super-aged societies,” where at least 20% of the population is over 65, around 2030.
The difference is the balance sheet underneath. U.S. per-capita gross domestic product was $55,264 in 2014, the year it became an aged society. Thailand’s stood at just $6,910 in 2022. Vietnam, China and even India are aging at much lower levels of wealth than the U.S. and European economies — working-age populations close to peaking or, like Thailand’s, already shrinking, staring at the prospect of far fewer young people supporting a growing cohort of aging adults.
What That Looks Like on the Ground
In a poor farming village west of Bangkok, Boonma Klahan, 57, starts her mornings by washing, changing and feeding her 85-year-old mother, who has dementia and spends her days on a mattress on the family home’s wooden floor. She makes breakfast for her 87-year-old father, then rides her motorbike to her job as a health aide to 22 other elderly people. Three of her charges are bedridden; most of the others can no longer leave their homes. The family scrapes by on the $90 a month Boonma receives for her work, her parents’ combined $50 old-age allowance from the government, and money sent by her adult children. “It’s getting more and more difficult to get by,” she said — her own back and knees starting to strain from lifting people without hospital beds or other specialized equipment.
Successive Thai governments have debated raising an old-age allowance that amounts to between $18 and $35 a month, and eventually discarded the idea for cost reasons. Seniors can apply for additional means-based support of as much as $90 a month. Beyond that, elderly people without savings or family have few options: a country of 71 million people has only 25 government-run old-age homes where care is low-cost or free, according to the Ministry of Social Development and Human Security. The World Bank forecasts that by the 2040s the number of Thais over 80 who need assistance will increase sixfold, to around 2.5 million.
Social networks remain strong in rural communities, says Nopphol Witvorapong, an economist at Chulalongkorn University in Bangkok who studies Thai family structures — neighbors step in, and local health aides pick up the slack. One model the government hopes to expand is paying families to “foster” seniors. One of its first beneficiaries is Aran Inthakul, 71, a former car mechanic who struggles to move after a fall several years ago. His neighbor Lucksana Tohtrakarn, 67, now receives $60 a month to help him with meals, bathing and other necessities. “I felt empathy for him,” she says, “because he was always alone.”
Demographics is the slowest, surest macro force we track — it moves on a thirty-year clock and it has never once been surprised by a Fed meeting. It is why our developed-market and healthcare sleeves lean where they lean, and why long-term-care planning is a first-world privilege worth actually using.
Action: no trade from a single feature. The read is structural: the U.S. gets to fund its aging with a $55,000-per-head economy, and the countries that cannot are about to test every social contract in Asia. That is a reason to own emerging-market exposure through breadth rather than conviction, and a reason to take the long-term-care conversation seriously while it is still a choice.
