Over the past 20 years, a growing number of young girls—disproportionately Black girls—have been criminalized and subjected to criminal and juvenile legal involvement. Notably, these girls have often experienced numerous forms of trauma before their involvement in the system, including poverty, racism, sexism, heterocentrism and transphobia, child physical and sexual abuse, sexual assault, dating violence, and exploitation. This monograph outlines common pathways to confinement for young Black girls and outlines strategies for engaging them and supporting their successful reentry into the community.
