World-wide estimates of child labour vary -

As per the UNICEF in the age group of 5-17 years - 317 million children are 'economically active'

As per another source -

About 246 million children ages 5 to 17 worldwide are involved in child labour - about 1 out of every 6 children in the world. Nearly three-quarters of the world's child labourers, about 180 million children, are exposed to the worst forms of child labour - that is, work that is hazardous for children. Some 110 million children in hazardous work are under age 15. Some estimated 8.4 million children are trapped in the most abhorrent forms of child labour - slavery, trafficking, debt bondage, prostitution, pornography and other such activities.
