Undocumented Immigrant Offending Rate Lower Than U.S.-Born Citizen Rate

An NIJ-funded study examining data from the Texas Department of Public Safety estimated the rate at which undocumented immigrants are arrested for committing crimes. The study found that undocumented immigrants are arrested at less than half the rate of native-born U.S. citizens for violent and drug crimes and a quarter the rate of native-born citizens for property crimes.[1]

The question of how often undocumented immigrants commit crimes is not easy to answer. Most previous research on crime commission by immigrant populations has been unable to differentiate undocumented immigrants from documented immigrants. As a result, most studies treat all immigrants as a uniform group, regardless of whether they are in the country legally.

The estimates in this study come from Texas criminal records that include the immigration status of everyone arrested in the state from 2012 to 2018. These data enabled researchers to separate arrests for crimes committed by undocumented immigrants from those committed by documented immigrants and native-born U.S. citizens. (For more detail on the study’s data sources and methodology, see the sidebar “What Makes the Texas Data Unique?”)

The researchers tracked these three groups’ arrest rates across seven years (2012-2018) and examined specific types of crime, including homicides and other violent crimes.[2] They used these arrest rates as proxies for the rates of crime commission for the three groups. It should be noted that arrest is a commonly used, but imperfect measure of crime that in part reflects law enforcement activity rather than actual offending rates.

During this time, undocumented immigrants had the lowest offending rates overall for both total felony crime (see exhibit 1) and violent felony crime (see exhibit 2) compared to other groups. U.S.-born citizens had the highest offending rates overall for most crime types, with documented immigrants generally falling between the other two groups.
