The 2001 national census of India estimated the total number of child labour, aged 5–14, to be at 12.6 million. The child labour problem is not unique to India; worldwide, about 217 million children work, many full-time.
In 2001, out of a 12.6 million, about 12 million children in India were in a hazardous job. UNICEF estimates that India with its larger population, has the highest number of labourers in the world under 14 years of age, while sub-saharan African countries have the highest percentage of children who are deployed as child labour. International Labour Organisation estimates that agriculture at 60 percent is the largest employer of child labour in India, while United Nation's Food and Agriculture Organisation estimates 70 % of child labour is deployed in agriculture and related activities. Outside of agriculture, child labour is observed in almost all informal sectors of the Indian economy.
