The Illinois prison population dropped to a five-year low in May, according to a state Department of Corrections report.
In May 2015, there were 47,483 inmates at Illinois prisons. The state prison population hasn't been that low since May 2010. That's when 47,150 prisoners were in the system.
The Illinois prison population has ticked down 3.7 percent from a January 2013 high of 49,321 prisoners.
Gov. Bruce Rauner, meanwhile, wants to see the state prison population shrink even more.
Under an executive order he signed in February, Rauner established a new state commission tasked with developing criminal justice and sentencing reforms. The commission has been charged with proposing reforms that would cut the state's current prison population by 25 percent by 2025.
The recent prisoner population decline is due in part to an early release program under former Gov. Pat Quinn and a decrease in the number of people sent to state correctional facilities.
Despite the drop, however, the state's correctional system is still overcrowded. It was designed for an inmate capacity of 32,000.
