Ohio: Increased Incarceration Had Limited Effect on Reducing Crime for Over Two Decades

February 12, 2015

Since 1990, increased incarceration had a limited impact on reducing crime nationwide, concludes a new report from the Brennan Center for Justice at NYU School of Law. In What Caused the Crime Decline?, a team of economic and criminal justice researchers examine over 40 years of data, gathered from 50 states and the 50 largest cities.

The report offers a close look at Ohio, where the prison population has more than doubled over the past 25 years. Ohio spent $1.798 billion on corrections in 2013. Experts found that increases in the average length of an individual's time spent incarcerated, in addition to increased prison admissions, primarily drove this expansion. As of 2013, Ohio imprisons 447 people per 100,000, compared to 496 for the U.S.

The Center will host a briefing call today at 1 p.m. ET to discuss the report’s findings. Dial In information: 1-800-514-0831; Confirmation Number: 38955210

Nationwide and Ohio-specific findings are summarized below:

  • Crime: Crime across the United States has steadily declined over the last two decades. From its height in 1981 to 2013, crime in Ohio dropped by 41 percent. And the national crime rate was cut in half.
     
  • Incarceration: Increased incarceration has been declining in its effectiveness as a crime control tactic for more than 30 years. It had some effect, likely in the range of 0 to 10 percent, on reducing crime in the 1990s. Since 2000, however, increased incarceration had a negligible effect on crime. In Ohio, incarceration’s effectiveness declined to a level that was essentially zero by 1997. A number of states, including California, Michigan, New Jersey, New York, and Texas, have successfully reduced their prison populations while crime continues to fall.
     
  • Other Factors: Increased numbers of police officers, some data-driven policing techniques, changes in income, decreased alcohol consumption, and an aging population played a role in the crime decline. In particular, the report finds CompStat is associated with a 5 to 15 percent decrease in crime. In Ohio, CompStat was introduced in Cleveland in 2005 and in Columbus in 2006. The report also includes new information on the effects of unemployment, the death penalty, and other theories on crime.

“Some have argued that despite the immense social and fiscal costs of America’s mass incarceration system, it has succeeded at reducing crime,” said report co-author Oliver Roeder. “But the data tells a different story: if reducing crime is the end goal of our criminal justice system, increased incarceration is a poor investment.”

“This report amplifies what many on the left and right have come to realize in recent years: mass incarceration isn’t working,” said Inimai Chettiar, director of the Brennan Center’s Justice Program. “A better use of resources would be improving economic opportunities, supporting 21st century policing practices, and expanding treatment and rehabilitation programs, all of which have proven records of reducing crime, without incarceration’s high costs.”

“This groundbreaking empirical analysis from the Brennan Center shows that, on examination, the easy answers do not explain incarceration’s effect on crime,” wrote Joseph Stiglitz, a Nobel laureate in economics and University Professor at Columbia University, in the Foreword. “This report presents a rigorous and sophisticated empirical analysis performed on the most recent, comprehensive dataset to date.”

“Ohio has taken some important first steps to reduce its prison population in recent years,” said Lauren-Brooke Eisen, report co-author. “While the state’s efforts to reduce maximum sentences for many crimes and strengthen community-based alternatives to prison are admirable measures, this report’s findings support additional reforms to reduce Ohio’s prison population – and prove this can be achieved without added crime.”
