"Allegations of sexual victimization in all types of juvenile facilities increased by 995 (76%) between 2013 and 2016 (table 1). During that period, allegations increased by 477 (66%) in state juvenile systems and by 518 (88%) in locally and privately operated facilities. These increases can be partly attributed to juvenile justice authorities’ response to the 2012 release of the National Standards to Prevent, Detect, and Respond to Prison Rape.4 From 2016 to 2018, the number of allegations generally remained stable across juvenile facilities, though they increased by 177 (15%) in state juvenile systems."
