IMPRISONMENT IN ILLINOIS

At year-end 2004, Illinois prisons housed 44,054 inmates serving sentences of more than one year. Of these inmates, 41,304 were male and 2,750 were female. With a female imprisonment rate of 43 female prisoners per 100,000 female residents Illinois ranked 34th in 2004. With an overall imprisonment rate of 346 prisoners per 100,000 residents in 2004, Illinois ranks 32nd in its imprisonment rate.

In 1977, Illinois prisons housed 277 female inmates; by 2004, the female prison population had reached 2,750. Illinois' female prison population was at its lowest with 236 female prisoners in 1978 and peaked at 2,849 female inmates in 2000.


GROWTH IN FEMALE IMPRISONMENT RATE

Between 1977 and 2004, Illinois' female prison population grew by 893% with an average annual percent change of 10.6% per year.

Throughout the period between 1977 and 2004, Illinois' female imprisonment rate was consistently below the average across states. Beginning in 1999, Illinois' female imprisonment rate began to fall each year and then increased again slightly between 2002 and 2004. In 2004, Illinois' female imprisonment rate remained substantially below average.


MALE TO FEMALE IMPRISONMENT RATIO

The male to female imprisonment ratio indicates the number of male inmates for every female inmate. Although both female and male imprisonment rates have increased over the period of study, a shrinking ratio suggests that the number of female prisoners has increased at a faster pace. In 1977, across the states, there were an average of 26 male prisoners for every female prisoner; by 2004, this ratio had fallen to 13 male prisoners for every female prisoner. Illinois' 1977 ratio was substantially higher than average with 40 male prisoners for every female prisoner. In 2004, Illinois' male to female imprisonment ratio (15:1) was just slightly higher than the average across states.


CORRECTIONAL FACILITIES

According to the 2000 Census of State and Federal Correctional Facilities, Illinois has 48 correctional facilities. Of Illinois' 48 correctional facilities, 39 house male prisoners only, four house female prisoners only, and five house both male and female prisoners.
