According to the White House Office of the Press Secretary, a recent Executive Order on Border Security and Immigration Enforcement was intended to address the issue of “significant increase in violent crime” due to immigration driven by “transnational criminal organizations.” These claims directly contradict the results of academic work on immigration and crime, and a recent study published in the Journal of Ethnicity in Criminal Justice reinforces that. It shows that immigration is not linked to increases in crime—in fact, this study suggests it’s linked to reductions in certain types of crimes.
This study builds on previous findings on arrests and criminal offenses. That previous data showed that foreign-born residents of the US were less likely to commit crimes than native-born Americans. The new study looked at 200 major metropolitan areas as defined by the US Census Bureau. The researchers then used Census data and FBI crime reporting data from 1970-2010 to look at trends for these regions.
The authors were interested in increases in crimes that might be attributable to an influx of immigrants who decreased economic opportunities or ended up in jobs that might otherwise have gone to local-born residents. To that end, they looked at violent crimes and property crimes, including rates of murder, non-negligent manslaughter, aggravated assault, robbery, burglary, and larceny.
