There is a piece of research that was not conducted by IJM but that did affirm what we have encountered, which is that children, especially in the slave labour industry in South Asia, are often recruited in family units. Their parents are recruited, and as a result, because children can increase productivity and output, they will be recruited alongside the parents. The entire family unit will then be found in a situation of slavery.
