Almost all are boys. Another very large occupation is domestic service. Huge numbers of girls live and work in other people's homes as maids. Nobody knows how many domestic servants there are exactly, but it is very high indeed. Estimates for Dhaka alone range from 200.000 to one million, of which almost all are girls.
Scavengers are probably the third largest group.
An estimated 100.000 waste collectors of various kinds in Dhaka roam around rubbish dumps or wander the streets. Up to one-third are girls. Workers in small informal factories are almost all boys. The younger boys are to be found in industries such as jewellery and shoes. Older boys are more likely to be found in places as welding, automobile and engineering workshops, as well as in the furniture, glass and electrical wire industries.
