Chicago gave hundreds of high-risk kids a summer job. Violent crime arrests plummeted.

Chicago gave hundreds of high-risk kids a summer job. Violent crime arrests plummeted.

A couple of years ago, the city of Chicago started a summer jobs program for teenagers attending high schools in some of the city’s high-crime, low-income neighborhoods. The program was meant, of course, to connect students to work. But officials also hoped that it might curb the kinds of problems — like higher crime — that arise when there’s no work to be found.

Research on the program conducted by the University of Chicago Crime Lab and just published in the journal Science suggests that these summer jobs have actually had such an effect: Students who were randomly assigned to participate in the program had 43 percent fewer violent-crime arrests over 16 months, compared to students in a control group.

The results echo a common conclusion in education and health research: that public programs might do more with less by shifting from remediation to prevention. The findings make clear that such programs need not be hugely costly to improve outcomes for disadvantaged youth; well-targeted, low-cost employment policies can make a substantial difference, even for a problem as destructive and complex as youth violence.

That number is striking for a couple of reasons: It implies that a relatively short (and inexpensive) intervention like an eight-week summer jobs program can have a lasting effect on teenage behavior. And it lends empirical support to a popular refrain by advocates: “Nothing stops a bullet like a job.”
