Asia's Economy of One Reshapes Spending, Care and Business
More people in parts of Asia are living by themselves.
This is happening especially in China, South Korea, Japan and Singapore.
When fewer people share a home, each person must pay for more things alone.
They may buy prepared meals, cleaning, care or safety services that families once provided.
Companies are creating products such as single-serving food and solo travel.
Older people who live alone may need extra help with healthcare and emergencies.
Living alone does not always mean feeling lonely, although solo households report loneliness more often in South Korea.
New businesses, including some AI services, are trying to provide companionship and support.
This change is helping create what analysts call an economy of one.
One-person households are increasing across China, South Korea, Japan and Singapore as household sizes shrink.
Solo households often spend relatively more on housing, utilities, eating out and accommodation than larger households.
Cooking, cleaning, childcare and eldercare traditionally handled within families are increasingly becoming paid market services.
The combination of solo living and ageing is raising concerns about healthcare, caregiving, safety and social support.
Businesses are developing single-serving meals, solo travel, safety tools, paid companionship and AI-based interaction services for people living alone.

New markets and individual choice
Rising costs and social vulnerabilities
Economic opportunity
New markets and individual choice
Businesses can meet growing demand with single-serving meals, solo travel, safety tools, care services, paid companionship and AI interaction.
Rising costs and social vulnerabilities
As family-provided work moves into the marketplace, individuals may have to purchase services that were previously shared or provided within households.
Living alone and wellbeing
New markets and individual choice
Living alone is not automatically the same as loneliness and can be supported through products, services and social tools designed for individuals.
Rising costs and social vulnerabilities
Solo households report higher loneliness in South Korea, and people living alone may face greater risks involving emergencies, caregiving and lack of routine check-ins.
Technology and companionship
New markets and individual choice
Check-in applications and AI services can provide alerts or interaction for people living alone.
Rising costs and social vulnerabilities
China's rules for human-like AI interaction services include safeguards concerning emotional dependence, excessive use, self-harm and minors, indicating concerns about possible harms.
