IMPRISONMENT
IN IOWA
At
year-end 2004, Iowa prisons housed 8,525 inmates serving sentences
of more than one year. Of these inmates, 7,768 were male and
757 were female. With its 2004 female imprisonment rate of
50 female prisoners per 100,000 female residents, Iowa ranks
29th. With an overall imprisonment rate of 288 prisoners per
100,000 residents, Iowa is 39th in the overall imprisonment
rate rankings.
In
1977, Iowa prisons housed 84 female inmates; by 2004, the
female prison population had reached 757. Iowa's female prison
population was at its lowest with 71 female prisoners in 1978
and peaked at 757 female inmates in 2004.

GROWTH
IN FEMALE IMPRISONMENT RATE
Between
1977 and 2004, Iowa's female prison population grew by 801%
with an average annual percent change of 9.2% per year.
Iowa's
female imprisonment rate has consistently fallen below the
average across states. Although below average in its female
imprisonment rate, Iowa is not among the least punitive states
in this regard, and is ranked notably higher (29th) in its
punitiveness toward female offenders than it is in its punitiveness
overall (39th).

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. Iowa's 1977 ratio
was slightly lower than average with 24 male prisoners for
every female prisoner. In 2004, Iowa's male to female imprisonment
ratio (10:1) remained lower than the average across states.
CORRECTIONAL
FACILITIES
According
to the 2000 Census of State and Federal Correctional Facilities,
Iowa has 30 correctional facilities. Of Iowa's 30 correctional
facilities, 15 house male prisoners only, two house female
prisoners only, and 13 house both male and female prisoners.
