Statistics from UNICEF about child exploitation:

Millions of girls work as domestic servants and unpaid household help and are especially vulnerable to exploitation and abuse. Millions of others work under horrific circumstances. They may be trafficked (1.2 million), forced into debt bondage or other forms of slavery (5.7 million), into prostitution and pornography (1.8 million), into participating in armed conflict (0.3 million) or other illicit activities (0.6 million). However, the vast majority of child labourers – 70 per cent or more – work in agriculture.

Surveys indicate that 30 to 35 per cent of all sex workers in the Mekong sub-region of Southeast Asia are between 12 and 17 years of age.
Mexico’s social service agency reports that there are more than 16,000 children engaged in prostitution, with tourist destinations being among those areas with the highest number. In Lithuania, 20 to 50 percent of prostitutes are believed to be minors. Children as young as age 11 are known to work as prostitutes. Children from children’s homes, some 10 to 12 years old, have been used to make pornographic movies.

An estimated 300,000 child soldiers - boys and girls under the age of 18 - are involved in more than 30 conflicts worldwide. Child soldiers are used as combatants, messengers, porters, cooks and to provide sexual services. Some are forcibly recruited or abducted, others are driven to join by poverty, abuse and discrimination, or to seek revenge for violence enacted against themselves and their families.
