They are everywhere but they are invisible, working in homes, shops and plantations.

Millions of girls who work as unpaid domestic servants are vulnerable to exploitation and abuse. Millions of others work under horrific circumstances: they are trafficked (12 million), forced into several forms of slavery (57 million), into prostitution and pornography(18 million), into participating in armed conflict (0,3 million) or other illicit activities (0,6 million). However, the vast majority of child laborers – 70 per cent or more – work in agriculture.
The Brazilian Household Survey ( Pesquisa Nacional por Amostra de Domicílios – PNAD) which was published in October 2002 confirmed that 2.9 million children between the ages of 5 and 15 still worked in Brazil. In 1992 there were about 8 million laboring children and in 1995 that number dropped to about 4.5 million.
