Child Labour: Economics and Ethics

Why child labour persists, the economic and moral arguments around it, and which policies have reduced it most effectively.

The International Labour Organization and UNICEF estimated in 2021 that around 160 million children worldwide were in child labour, nearly one in ten children. After years of decline, the number had risen slightly. Most child labour is in agriculture, often on family farms.

Why it persists

Poverty: families may depend on children’s earnings or work to survive.
Lack of schools or poor-quality schools that make education seem less valuable.
Shocks: when a parent falls ill or a harvest fails, children may be sent to work.
Demand for cheap labour in some industries.
Social norms.

The ethical debate

Almost everyone agrees that hazardous work, forced labour and work that prevents schooling harm children and should end. But there is debate about the best approach:

Some argue for strict bans and boycotts of products made with child labour.
Others warn that bans without addressing poverty can push children into worse, hidden work. A famous example: after a proposed U.S. law in the 1990s threatened to ban imports from factories using child labour, many Bangladeshi garment factories dismissed child workers, and reports suggested some children moved into more dangerous jobs.

What works

Evidence points to policies that change families’ circumstances:

Conditional cash transfers: programmes like Mexico’s Progresa and Brazil’s Bolsa Família, which pay families when children attend school, reduced child labour.
Free, good-quality schools nearby, including school meals.
Social protection that helps families cope with shocks without sending children to work.
Enforcement against the worst forms, such as hazardous and forced labour.

India’s Right to Education Act of 2009 made education a fundamental right for children aged 6 to 14, and the Child Labour Amendment Act of 2016 banned employment of children below 14 in all occupations, with an exception for helping family businesses outside school hours.

Paying for school attendance

A poor family earns a small amount from a 12-year-old's farm work. A cash transfer that pays them if the child attends school replaces part of that income. The family keeps the child in school, and the child gains education that raises future earnings. The transfer changes the family's economic calculation.

Thinking bans alone end child labour

Bans are important, especially against hazardous work, but without addressing poverty and school quality, children may simply move into less visible work. Lasting reductions come from combining enforcement with support for families and schooling.

Key takeaways

Around 160 million children were in child labour worldwide in 2020, mostly in agriculture.
Poverty, poor schools, shocks and norms sustain child labour.
Bans without support can push children into worse hidden work.
Conditional cash transfers, good schools and social protection reduce child labour.
