Child labour is work that children are too young to do, or work that is likely to harm their health, safety or development. In 2024 an estimated 138 million children aged 5 to 17 were in child labour, almost 8% of all children in that age group, and 54 million of them were in hazardous work. That is far fewer than the 246 million counted in 2000, even though the world's child population grew by 230 million over the same period. It is also more than 20 million fewer than in 2020, reversing a rise between 2016 and 2020. Most child labour does not take place in factories: 61% is in agriculture, much of it on family smallholdings and in subsistence farming, 27% is in services such as domestic work and market selling, and 13% is in industry, including mining and manufacturing.
Sub-Saharan Africa has about 87 million children in child labour, nearly two-thirds of the global total. The share of children affected there has fallen, but because the child population is growing quickly, the number has not. Rates are highest in countries affected by conflict or fragility, and more than half of all children in child labour are only 5 to 11 years old. Child labour often costs children their education: nearly a third of those of compulsory school age are not in school, and children in child labour are more than 30% less likely to have basic reading and numeracy skills. Hazardous work can cause injury or illness with lifelong consequences. Child labour is closely linked to poverty, and the ILO and UNICEF warn that cuts in funding for education, social protection and child protection, together with climate change and conflict, could undo recent gains.
How child labour is defined and counted
Not all work done by children is child labour. The international definition draws on two ILO conventions: No. 138 on the minimum age for employment and No. 182 on the worst forms of child labour, the first ILO convention to be ratified by every member state. It draws the line by age, hours and type of work, and SDG indicator 8.7.1 tracks the share of children aged 5 to 17 in child labour. Four elements decide what is counted:
Age and working hours
Children aged 5 to 11 are counted as being in child labour if they do any economic work. Children aged 12 to 14 may do light work for fewer than 14 hours a week; 14 hours or more counts as child labour. Adolescents aged 15 to 17 may legally work in many countries, so they are counted only if their work is hazardous.
Hazardous work
For statistical purposes, work is hazardous if it is in mining, quarrying or construction, in one of 41 occupations that an ILO task force has judged dangerous for children, or if it lasts 43 hours or more a week. Hazardous work is counted as child labour at every age under 18.
Worst forms beyond hazardous work
Convention No. 182 also covers slavery-like practices and forced labour, the forced recruitment of children for armed conflict, commercial sexual exploitation and the use of children in illicit activities. Household surveys rarely capture these forms, so the global estimates undercount them.
Household chores and survey-based estimates
Unpaid household chores of 21 hours or more a week are counted only in a broader measure for children aged 5 to 14, which raises the share in child labour from 8% to 11%. The global figures are modelled from national household surveys in 107 countries that cover 60% of the world's children, with statistical imputation for countries without data.
