“There’s no question that some undocumented immigrants have committed heinous crimes. But there are many reasons to be doubtful that recent incidents are evidence of a surging migrant crime wave.
For one, crime is down in the cities that received the most migrants as a result of Texas’ busing operations under Operation Lone Star, per an NBC News analysis. “Overall crime is down year over year in Philadelphia, Chicago, Denver, New York and Los Angeles,” NBC News reported.
David J. Bier, associate director of immigration studies at the Cato Institute, a libertarian think tank, echoes that finding. “We don’t have real-time data, but the partial crime data that exist for this year show consistent declines in major crimes in major cities,” he says. “The most significant crime spike in recent years occurred in 2020—when illegal immigration was historically low until the end of the year.”
“National crime data, especially pertaining to undocumented immigrants, is notoriously incomplete,” since it “comes in piecemeal and can only be evaluated holistically when the annual data is released,” cautions NBC News. What’s more, “most local police don’t record immigration status when they make arrests.”
However, several analyses conducted at both the state and federal levels find that immigrants—including undocumented ones—are less crime-prone than native-born Americans. Looking at “two decades of research on immigration and crime,” criminologists Graham Ousey and Charis Kubrin found that “communities with more immigration tend to have less crime, especially violent crimes like homicide,” wrote The Washington Post‘s Glenn Kessler. A 2015 Migration Policy Institute report indicated that undocumented immigrants have a lower rate of felony convictions than the overall U.S. population does.
The Cato Institute’s “research has consistently shown that immigrants are less likely to commit crimes and less likely to end up incarcerated than natives,” Bier continues. An article this week by Alex Nowrasteh, vice president for economic and social policy studies at the Cato Institute, indicated that illegal immigrants have a lower homicide conviction rate in Texas than native-born Americans do, while legal immigrants have a lower conviction rate than both groups.”
