The US Department of State, in the June 2007 issue of its "Trafficking in Humans Report," stated:

“Sex trafficking would not exist without the demand for commercial sex flourishing around the world. The U.S. Government adopted a strong position against prostitution in a December 2002 policy decision, which states that prostitution is inherently harmful and dehumanizing and fuels trafficking in persons.

Prostitution and related activities—including pimping and patronizing or maintaining brothels—encourage the growth of modern-day slavery by providing a façade behind which traffickers for sexual exploitation operate. Where prostitution is tolerated, there is a greater demand for human trafficking victims and nearly always an increase in the number of women and children trafficked into commercial sex slavery. Few women seek out or choose to be in prostitution, and most are desperate to leave it. A 2003 scientific study in the Journal of Trauma Practice found that 89 percent of women in prostitution want to escape prostitution but had no other options for survival.”
