Data were gathered by the Children's Bureau of the Department of Health and Human Services. Findings showed that the number of juveniles in custody increased 12 percent between 1975 and 1985. In 1985 a juvenile in custody was likely to be a white male between ages 14 and 17. The most common type of facility was a halfway house or group home. Private facilities tended to be smaller than public facilities. Populations exceeded design capacity in 17 percent of the public facilities and 2 percent of the private facilities. The average daily cost per resident for a public facility was $69 in 1984. Length of stay averaged 41 days in public facilities and 126 days in private facilities in 1984.
