The problem of child labor exploitation is a major challenge to the progress of developing countries. Children work at the cost of their right to education which leaves them permanently trapped in the poverty cycle, without the education and literacy required for better-paying jobs. This is particularly serious in India as it tops the list with the highest number of child labourers in the world. The 2001 national Census of India estimated the total number of child labour, aged 5-14, to be at 12.6 million.
