Changing Directions: A Roadmap for Reforming Illinois’ Prison System

After decades of using incarceration as the country’s primary response to crime, leading Republicans and Democrats are embracing safe, fair, and cost-effective prison reform.

As Illinois prepares to elect its next governor, voters should ask the candidates where they stand on this issue and what their vision and goals are for the state’s crowded and under-resourced $1.3 billion prison system.

Like all states, Illinois’ prison population has grown exponentially over the past 40 years, going from around 6,000 inmates in 1974 to 49,000 today, despite the fact that the system was designed to hold only 32,000.

Two policy trends, promoted by both political parties, drove this dramatic increase. Throughout the 1980s and 90s, policymakers expanded the number of offenses for which a person could be sent to prison, particularly low-level offenses, and they also increased the length of time offenders serve for more serious crimes.

While policymakers hoped this increased use of prison would improve public safety outcomes, a growing consensus of research and experience has found that overusing incarceration produces a host of harmful, unintended consequences.

Though prison can effectively incapacitate people who pose risks to public safety, research has shown that it transforms low-risk offenders into high-risk offenders and makes it difficult for all prisoners to re-integrate back into society when they are released.

Prison is also the state’s most expensive form of punishment. Illinois spends about $22,000 to house an inmate for one fiscal year. That amount is about four times the average cost of diversion programs for low-level non-violent offenders that are funded through Adult Redeploy Illinois, the state’s most successful and effective alternative-to-incarceration program.

The only way for Illinois to get a handle on its prison system is to safely reduce its overreliance on incarceration. This needed change can come in one of two ways.

The first is the predicament in which California now finds itself. After failing to reduce its prison population and address conditions that endangered inmates and staff, the Supreme Court of the United States ordered California in 2011 to reduce its prison population by more than 30,000 people. Three years and several hundred million dollars later, California is still struggling to fulfill the Court’s mandate.

The second option is to follow the example of states like Georgia, Kentucky, Texas, and New York that have used reforms in law and policy to safely decrease their prison populations and the crippling costs of incarceration.
