Globally, there were only 7,705 prosecutions and 4,746 convictions for human trafficking crimes in 2012. In the United States, there were 2,515 suspected incidents of human trafficking investigated between January 2008 and June 2010. Of these, more than 80 percent of the victims of sex trafficking were U.S. citizens or nationals, and more than 90 percent of the victims of labor trafficking were undocumented or qualified aliens.
