A new study co-authored by Associate Professor Santiago Pérez shows that for the past 150 years, immigrants in the United States have had lower incarceration rates than those born here, and new research shows that since the 1960s that gap has significantly grown. This new analysis was a data-driven effort to compare the rates at which immigrants and people born in the U.S. commit crime. This paper is also the first to compare incarceration rates over such a long period of time. Read the story.
