UNLIKE ITS PREDECESSORS, THE 1974 PROJECT COVERED PRIVATELY OPERATED JUVENILE DETENTION AND CORRECTIONAL FACILITIES AS WELL. THE ADVANCE REPORT SHOWS, FOR PUBLIC FACILITIES IN EACH STATE AND LEAA REGION, THE NUMBER OF FACILITIES AND JUVENILES HELD, THE DETENTION STATUS OF JUVENILES HELD, THE KINDS OF OFFENSES OF ADJUDICATED DELINQUENTS AND PERSONS DECLARED IN NEED OF SUPERVISION, STAFFING, AND EXPENDITURES. SEVERAL OF THESE 1974 STATISTICS ARE COMPARED WITH 1971 AND 1973. THE 1974 PRIVATE FACILITY DATA SHOWN IS SIMILAR IN NATURE TO THE VARIABLES PRESENTED FOR PUBLIC FACILITIES. THE FINAL REPORT FOR THIS CENSUS, TO BE PUBLISHED IN MID-1977, WILL PROVIDE STATISTICS IN GREATER DETAIL AND SHOW ADDITIONAL DATA VARIABLES SUCH AS AVERAGE LENGTH OF STAY, JUVENILE AGE RANGES, AND ADMISSIONS AND DEPARTURES DURING THE YEAR.
