Average daily population figures for May 1990 are collapsed into male and female categories for both adult and juvenile inmates. These population figures are also categorized into felony, misdemeanor, and "other" subcategories to facilitate interpretation. Within both felony and misdemeanor subcategories, the number of inmates held for trial or sentencing and those detained or sentenced for violation of probation are presented for May 1990. The "other" subcategory documents the number of parole violators, State inmates, undocumented aliens, holdings for other jurisdictions, and individuals detained under the Baker (mental health) and Myers (alcoholism) Acts. Additionally, the average daily population figures, the incarceration rates for each county, the number of overcrowded county detention facilities, and the pretrial inmate levels for each facility are included. County detention facilities with amended capacities since April 1990 are indicated. On average, there were 33,520 inmates in Florida's county detention facilities during May 1990, a 0.2-percent increase in the inmate population from that reported for April 1990. 4 tables and 3 figures
