The latest global estimates indicate that the number of children in child labour has risen to 160 million worldwide – an increase of 8.4 million children in the last four years. 63 million girls and 97 million boys were in child labour globally at the beginning of 2020, accounting for almost 1 in 10 of all children worldwide. This report warns that global progress to end child labour has stalled for the first time in 20 years. The number of children aged 5 to 17 years in hazardous work – defined as work that is likely to harm their health, safety or morals – has risen by 6.5 million to 79 million since 2016. In sub-Saharan Africa, population growth, extreme poverty, and inadequate social protection measures have led to an additional 16.6 million children in child labour over the past four years.
