The National Human Trafficking Hotline maintains one of the most extensive data sets on the issue of human trafficking in the United States. The statistics contained on this website are based on aggregated information learned through signals — phone calls, emails, and online tip reports — received by the Hotline. The data do not define the totality of human trafficking or of a trafficking network in any given area. The National Hotline uses this data to help human trafficking victims and survivors and to provide the anti-trafficking field with information to help combat all forms of human trafficking.
