The criminalization of immigration

Immigrants are Less Likely to be Criminals Than the Native-BornHigher Immigration is Associated with Lower Crime Rates

• Between 1990 and 2013, the foreign-born share of the U.S. population grew from 7.9 percent to 13.1 percent and the number of unauthorized immigrants more than tripled from 3.5 million to 11.2 million.
• During the same period, FBI data indicate that the violent crime rate declined 48 percent—which included falling rates of aggravated assault, robbery, rape, and murder. Likewise, the property crime rate fell 41 percent, including declining rates of motor vehicle theft, larceny/robbery, and burglary. 

Immigrants are Less Likely than the Native-Born to Be Behind Bars 

• According to an original analysis of data from the 2010 American Community Survey (ACS) conducted by the authors of this report, roughly 1.6 percent of immigrant males age 18-39 are incarcerated, compared to 3.3 percent of the native-born. This disparity in incarceration rates has existed for decades, as evidenced by data from the 1980, 1990, and 2000 decennial censuses. In each of those years, the incarceration rates of the native-born were anywhere from two to five times higher than that of immigrants.
• The 2010 Census data reveals that incarceration rates among the young, less-educated Mexican, Salvadoran, and Guatemalan men who make up the bulk of the unauthorized population are significantly lower than the incarceration rate among native-born young men without a high-school diploma. In 2010, less-educated native-born men age 18-39 had an incarceration rate of 10.7 percent—more than triple the 2.8 percent rate among foreign-born Mexican men, and five times greater than the 1.7 percent rate among foreign-born Salvadoran and Guatemalan men.

Immigrants are Less Likely Than the Native-Born to Engage in Criminal Behavior 

• A variety of different studies using different methodologies have found that immigrants are less likely than the native-born to engage in either violent or nonviolent “antisocial” behaviors; that immigrants are less likely than the native-born to be repeat offenders among “high risk” adolescents; and that immigrant youth who were students in U.S. middle and high schools in the mid-1990s and are now young adults have among the lowest delinquency rates of all young people.
