The major factors and assumptions upon which the projections are based are the male felon admission rate, significant chaptered legislation and initiatives, the Inmate Work/Training Incentive Program, cases on work furlough and parole, worktime credits for return-to-custody cases, mean sentences and preconfinement credits, placement need projections, and parole violators. The fall 1987 projection indicates that the institutional population will rise at a slower rate in fiscal 1987-88 and then increase at a higher rate than projected in spring 1987, due to higher admission rates and an increased number of parole-violator returns anticipated. The spring 1987 projections estimate the total institutional population to be 74,045 by June 30, 1988, and to increase to 97,710 by June 30, 1991. The fall 1987 projections estimate that the June 30, 1988, population will be 73,415, increasing to 99,080 by June 30, 1991 and to 104,780 by June 30, 1992. 5 figures and 18 tables.
