Immigrants are less likely to commit crime than America's native-born population, according to a report published this week by Time Magazine.

The study, commissioned by the Public Policy Institute of California, found that among men aged 18-40, the population most likely to be imprisoned, that American citizens are 10 times more likely to be imprisoned than immigrants.

The PPIC report comes on the heels of a similar survey taken in Chicago prisons that indicated that first-generation Mexican immigrants are 45% less likely to engage in violence than third-generation American citizens.

Both studies come at a time when prison populations in the United States are increasing. A February study by the Pew Center for Public Policy research found that 1 in 99 Americans are currently incarcerated.
