After June 1987, the inmate population will increase at a higher rate than projected in fall 1986, primarily due to higher admission rates and the return of more parole violators to prison. The spring 1987 projections are that the June 30, 1987, population will be 64,515 (620 less than projected in fall 1986), increasing to 97,710 by June 30, 1991 (2,760 more than projected in fall 1986). The spring 1987 parolee population projection of 37,820 for June 30, 1987, is 375 higher than that projected in fall 1986. By June 30, 1989, the number of parolees and outpatients is projected to be 49,440, increasing to 60,805 by June 30, 1991. These projections are 1,395 and 1,895 lower, respectively, than those made in fall 1986. The decrease in the civil narcotic addict institutional populations since the mid-1970's has reversed due to a steady increase in admissions beginning in early 1983. The addict institutional population, which was 1,394 on December 31, 1986, is expected to increase to 2,000 by June 30, 1991. The number of outpatients is expected to increase from 1,226 on December 31, 1986, to 2,275 on June 30, 1991. 10 tables and 5 figures.
