I'll start at the highest level. The ILO estimates there are 218 million children who are in some sort of employment. Of that there is a subset of 152 million children in child labour. Of that there is a subset of 73 million children in hazardous work. Of that there is a subset of 4.3 million children in forced child labour.
To answer your question, we talk about child labour and forced labour as distinct concepts. We often think of them as sitting along a continuum of labour exploitation, but certainly when we're talking about the whole sphere of child labour, we think it's something that needs to be addressed and eradicated. It's something that has a detrimental impact on children.
