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.
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.
IN FEMALE IMPRISONMENT RATE
1977 and 2004, Illinois' female prison population grew by
893% with an average annual percent change of 10.6% per year.
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.
TO FEMALE IMPRISONMENT RATIO
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.
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.
