Estimates do vary, but the numbers of individuals trafficked annually is said to range in the hundreds of thousands or millions. The organizations and resources devoted to anti-trafficking endeavors have increased since the existence of the traffic seeped into public awareness. For example, the U.S. State Department's annual Trafficking in Persons Report -- the "TIP Report" about which IntLawGrrl Janie Chuang also posts above -- is an invaluable resource for scholars and activists in the field.
A new resource is now available: At its Second Annual Symposium, "Incorporating Trafficking in Persons in Human Rights Curricula in Universities in the United States and Abroad," in 2008, The Protection Project established the Association of Scholars of Trafficking in Persons. In accordance with the Association’s vision, The Protection Project has launched a resource on its website for individuals and organizations seeking information about human trafficking and model syllabi for teaching the subject.
The syllabi are organized so as to facilitate various entry points and angles for studying the subject: gender studies, human rights, criminal law, the trade in humans as an illicit market. I encourage students, scholars and activists around the world to visit and benefit from this new database.
