Here are some amazing stats I read in this article about transnational crime and punishment (in particular the sex trade):
"UNICEF estimates that there are 400,000 child prostitutes in Thailand, and that half of those involved in prostitution are trafficked; that is, they are sold or traded to brothel owners. Reports by non-governmental organizations put the number of adult female prostitutes at 300,000 and children at 75,000 in the Philippines and between 10,000 and 15,000 prostitutes in Cambodia. The problem is not limited to Asia. In San Jose, the capital of Costa Rica, there are an estimated 2,000 girl child prostitutes. 2,000 child prostitutes in Guatemala City; 25,000 in the Dominican Republic; and as many as 500,000 in Brazil."
Don't think this is just a capitalist excess:
"Cuba receives as many as 200,000 male sex tourists every year"
