"Immigrants are less likely to commit crimes or to be incarcerated than native-born Americans. A 2007 study by the Immigration Policy Center found that the incarceration rate for immigrant men ages 18 to 39 in 2000 was 0.7 percent, while the incarceration rate for native-born men of the same age group was 3.5 percent. While the foreign-born share of the U.S. population grew from 8 percent to 13 percent between 1990 and 2010, FBI data indicate that violent crime rates across the country fell by about 45 percent, while property crime rates fell by 42 percent."
