A number of Socio-economic and demographic factors determine/influence the incidence of child labour in general as well as in the brick Kiln industry which is a significant employer of Child labour in the country. The extensiveness of supply and demand side factors makes eradication of child labour a very difficult task. Poor people tend to send their children to work to augment their income. Therefore, the poverty variable is one of the important determinants of the supply of child labour. It is not, however, clear, which is the cause and which is effect between poverty and child labour. It is possible that child labour can perpetuate poverty. In case of brick kilns, it's especially true where working in the brick kilns has become inter- generational occupation. The' deprivation of education and negligent accumulation of social and economic capital even after working in the brick kilns over long period of time has resulted in to the perpetuation of the child labour in the family. It was observed from the field that majority of labourers started as child labouer along with their parents some 20- 25 years ago and now their children are working with them.
