Little is known about how facility-level characteristics affect the risk of suicide and suicide attempts in juvenile justice residential facilities. This leaves facility administrators and mental health providers without evidence-based guidance on how the facility itself affects risks. The current study uses data from two recently developed censuses of juvenile justice facilities in the United States to examine the relationship between facility-level characteristics and the likelihood of a facility reporting serious suicide attempts and deaths from suicide. Results suggest highest risks for facilities housing larger populations of Black young people and for facilities locking sleeping room doors. Lower risks are found for facilities screening all young people within 24 hours of arrival.
