US Department of State
The US Department of State Office to Monitor and Combat Trafficking in Persons is an excellent place to find detailed information about human trafficking around the world. Each year the office produces a Trafficking in Persons Report. It is the most comprehensive worldwide report on the efforts of governments to combat severe forms of trafficking in persons.
