This report presents the 2018 Atlanta Youth Count (AYC18) study of sex and labor trafficking among youth experiencing homelessness in metropolitan Atlanta. The researchers used capture-recapture field sampling methods to locate homeless youth, ages 14 to 25, who did not have a permanent, stable residence and were living independently without consistent parental or family support. The study participants completed a brief survey about their demographic background, history of homelessness, including exploitative sex and labor trafficking involvement, and certain social experiences and behavioral characteristics. The report concludes that lesbian, gay, bisexual, and transgender (LGBT) youth are at higher risk of being trafficked; gender identity definitions need further understanding to help LGBT youth who are trafficking victims; early intervention is critical to preventing trafficking; and trauma-informed care is necessary to help youth who have been trafficked.
