"In 2018, juvenile justice administrators reported 2,467 allegations of sexual victimization in state juvenile systems and locally or privately operated juvenile facilities (figure 1). Of those allegations, 321 were substantiated based on a follow-up investigation. Sexual victimizations include youth-on-youth nonconsensual sexual acts and abusive sexual contact, and staff sexual misconduct and sexual harassment.1 The number of sexual victimization allegations rose 89% from 2013 to 2018, while the number of substantiated incidents grew 44%. The overall rate of reported allegations increased from 21.7 per 1,000 youth in juvenile facilities in 2013 to 54.1 per 1,000 in 2018. Youth made a total of 12,060 allegations from 2013 to 2018, more than half (52%) of which were allegedly perpetrated by staff. About 8% of these staff-on-youth allegations were substantiated, compared to 23% of youth-on-youth allegations."
