today—more than any other time in history.
218 million children aged 5 - 17 are involved in child
labor worldwide.
Globally, 1 in 6 children work.
Children below the age of 18 years represent between

agricultural labor as young as 5-7 years old.
126 million children work in hazardous conditions,
often enduring beatings, humiliation and sexual
violence by their employers.
The highest numbers of child laborers are in the
Asia/Pacific region, where there are 122 million working
children.
The highest proportion of child laborers is in Sub
Saharan Africa, where 26 percent of children (49
million) are involved in work.
