"Federally funded human trafficking task forces opened 2,515 suspected incidents of human trafficking for investigation between January 2008 and June 2010 (figure 1). Most suspected incidents of human trafficking were classified as sex trafficking (82%), including more than 1,200 incidents with allegations of adult sex trafficking and more than 1,000 incidents with allegations of prostitution or sexual exploitation of a child. Eleven percent of the suspected incidents opened for investigation were classified as labor trafficking, and 7% had an unknown trafficking type. Data in this report are from the Human Trafficking Reporting System (HTRS), which was designed to measure the performance of federally funded task forces. HTRS is currently the only system that captures information on human trafficking investigations conducted by state and local law enforcement agencies in the United States. This report is the second in a Bureau of Justice Statistics (BJS) series about the characteristics of human trafficking investigations, suspects, and victims. It reports about case outcomes, including suspect arrests and the visa status of confirmed victims, and describes the characteristics of incidents entered into the HTRS prospectively by the task forces beginning in 2008. The Methodology details the HTRS data collection procedures and data quality issues."
