After the 1972 Gates v. Collier federal judge ruling, the State of Mississippi replaced its previous inmate housing units, called "cages", with barracks buildings surrounded by barbed wire-topped fences. John Buntin of "Governing Magazine" said that the new units were "hastily built." Several MSP units were built in the 1970s; 3,080 beds were added for a total cost of $25,345,000. In the 1980s Mississippi State Penitentiary had 21 scattered camps. In 1983 Camp 25 served as the female unit, and the unit had no parking facilities. After Central Mississippi Correctional Facility opened, the women were moved out of Camp 25. In the 1990s MSP had 6,800 prisoners; in 1990 Mississippi had a population of 2,573,216, so about .026% of Mississippi's population was incarcerated in MSP at that time. The prison population had been increasing rapidly over the decade leading to 1995, and the prison officials converted a gymnasium into inmate housing and still faced overcrowding. Many construction projects occurred during that time.
