Trafficking in people for prostitution and forced labor is one of the most prolific areas of international criminal activity and is of significant concern to the United States and the international community. The overwhelming majority of those trafficked are women and children. According to the most recent Department of State estimates, roughly 800,000 people are trafficked across borders each year. If trafficking within countries is included in the total world figures, official U.S. estimates are that some 2 to 4 million people are trafficked annually.
