Asia’s ‘economy of one’: How solo living is reshaping spending, care and business

The rise of one-person households across parts of Asia is changing how people live, spend, eat, age and access care, creating new markets around the needs of individuals who once relied more heavily on families for housing, meals, companionship and everyday support.The shift is particularly visible in China, South Korea, Japan and Singapore, where household sizes are shrinking, and the share of people living alone is rising. The trend is creating what the accompanying analysis describes as an “economy of one” — as needs traditionally met within households increasingly become individual purchases or market services.Also read: Chinese Yuan rises to strongest level since 2022 after PBOC fixingAsia’s households are getting smallerChina’s average household size fell from 3.10 people in 2010 to 2.62 in 2020 and 2.52 in 2025, according to national statistics data.South Korea saw the share of one-person households rise from 27.2% in 2015 to 36.1% in 2024. In Japan, one-person households accounted for 38% in 2020 and are projected to reach 44.3% by 2050.Singapore has also seen the share rise, from 11.2% in 2014 to 16.1% in 2024.The trend is not simply about fewer people sharing a home. When households become smaller, costs and responsibilities that were once shared — from housing and meals to care and everyday risks — increasingly have to be managed by individuals.Living alone changes spending patternsData from South Korea’s Ministry of Data and Statistics shows that solo households have a different spending profile from households overall.In 2024, solo households had an income index of 46 and a consumption-spending index of 58, with all households set at 100. They also spent a larger share of their monthly budgets on housing and utilities, at 18.4% compared with 12.2% for all households.Similarly, spending on eating out and accommodation accounted for 18.2% of the budget for solo households, compared with 15.5% for all households.From household work to market servicesAs household sizes shrink, some tasks traditionally carried out within families can move into the market.Cooking at home does not count as a market transaction, while buying a prepared meal does. Similarly, cleaning one’s own home is unpaid household work, whereas hiring a cleaner turns that activity into a market service.The same applies to childcare and eldercare: care provided within the household is outside measured market activity, while hiring a childcare provider or caregiver creates a paid service. The analysis describes this as “an old household function moving into the marketplace.”That creates opportunities for businesses selling products and services specifically designed for people living alone — from single-serving meals and solo travel to paid companionship, safety services and care.Ageing is adding another dimensionThe growth of solo households is also intersecting with Asia’s ageing population.In South Korea, 41.3% of households are projected to contain one person by 2052, while 42.2% of those solo households are projected to be headed by someone aged 70 or above.In Japan, the number of people aged 65 and above living alone is projected to rise from 7.38 million in 2020 to 10.84 million in 2050.This combination of living alone and ageing raises practical questions around healthcare, caregiving, safety and social support.Japan’s data also illustrates the potential risk of having no one routinely checking in. In 2025, 22,222 people living alone who died at home were discovered eight days or more after death, while 7,148 were discovered at least 31 days later, according to the Japan National Police Agency data.The figures do not automatically represent “lonely deaths”, but highlight a practical vulnerability associated with living alone.Loneliness and solo living are not the sameLiving alone does not necessarily mean being lonely. In South Korea, 48.9% of people in solo households said they felt lonely often or sometimes, compared with 38.2% of the overall population.Globally, the World Health Organisation estimates that one in six people are affected by loneliness, with around 871,000 deaths per year associated with loneliness.Businesses are beginning to sell for oneThe changing household structure is creating demand for products and services built around individual needs.The examples cited include single-serving meals, solo travel, entertainment, paid companionship and safety tools. In China, a “Are You Dead?” app is cited as a safety service for people living alone: users check in regularly, and if several check-ins are missed, a pre-set emergency contact is alerted.Artificial intelligence is also entering the companionship market. China’s rules governing human-like AI interaction services took effect in July 2026, with safeguards covering areas such as emotional dependence, excessive use, self-harm and use by minors. Such services must also make clear that users are interacting with AI rather than another person.The broader shift is therefore not simply demographic. As more Asians live alone, the economic functions once bundled into the family household are increasingly being separated, priced and sold as individual products and services — giving rise to an economy increasingly designed for one.
