Immigrants are far less likely than the average U.S. native to commit crime in California, according to this issue of California Counts. For example, among men ages 18-40 ” the age group most likely to commit crime ” the U.S.-born are 10 times more likely than the foreign-born to be in jail or prison. Even among noncitizen men from Mexico ages 18-40 ” a group disproportionately likely to have entered the United States illegally ” the authors find very low rates of institutionalization. Such findings suggest that longstanding fears of immigration as a threat to public safety are unjustified.
