The data were collected from facility records and juvenile court intake records and compiled by the Statistical Analysis Center. This report provides data on detention admission and length trends, the characteristics and alleged offenses of juveniles detained, and data on other detention policy and programming issues. On most topics, data are presented for the last 5 years: 1990 through 1994. The 15,197 juvenile secure detention admissions in 1994 constituted a 39-percent increase over 1990 and a 99-percent increase over 1980. Detentions in 1974, the earliest year available, were higher, totaling 16,385. The characteristics of juveniles detained statewide have remained fairly stable for the last 5 years, with slightly more than half being white and about half being 16 and 17 years old. Of all detentions, approximately half were for an original criminal offense, and about half were for various types of court-order violations. Over the last 5 years, the average length of all detentions increased by 28.6 percent, from 7.0 days to 9.0 days. Over the same period, the average dropped to a period of 1 day in jails and increased 17.7 percent to 9.3 days in detention centers. 8 tables and 10 graphs
