The growing awareness of human trafficking in the United States and abroad requires government and human services agencies to rethink old policies and develop new ones for identifying and serving victims. Child welfare agencies are on the front lines of these changes: Children and youth involved with the child welfare system due to abuse or neglect and then placed in foster care or group homes—as well as youth who are involved with the justice system, are homeless, or have run away—are all at high risk of being trafficked. Often, the lack of stability in their living situation, physical distance from friends and family, and emotional vulnerability put them at risk for traffickers who are actively seeking children and teens to exploit.
