New Research Finds that Immigrant Crime Is Still Low

Last year we published a blog summarizing the research on how immigrants affect the crime rate in the United States. There are two major types of studies that examine this question.

The first uses Census data of the institutionalized population to investigate immigrant versus native incarceration rates. Although the Census evidence isn’t perfect because of potential issues with reporting immigration status and different types of incarceration, these studies show that immigrants are less likely to be incarcerated than similarly-aged natives.  The second type is a macro-level or area study that looks at the crime rates in places that have experienced large waves of immigration.  These generally find that immigration either lowers or has little effect on crime rates.  The research on unauthorized immigrant crime rates is poor.

A few recent papers recently extended these findings.  The first by David Green seeks to determine whether immigrants affect violent and drug-related crime in the United States on the state-level.  It looks at state-level rates of violent crime and drug arrests pooled for the 2012-2014 years against pooled statistics on foreign-born and Mexican nationals by immigration status, specifically legal versus unauthorized immigrants.  Green finds no association between immigrant population size and increased violent crime.  However, he does find a small but statistically significant association between unauthorized immigrant population size and arrests for drug offenses.

Latest Immigration Reform Bulletin Examines Immigrant Crime Myth

The June issue of Cato’s monthly newsletter on immigration reform, just released, tackles the timely topic of “Immigrants and Crime: Perceptions vs. Reality.” The bulletin finds that, contrary to public perception, immigration has not caused higher crime rates, in Arizona or in the nation as a whole. In fact, one new study even suggests that a rising level of immigration in a city actually leads to lower crime rates.

According to bulletin editor and author Stuart Anderson, a Cato adjunct scholar, “National studies have reached the conclusion that foreign-born (both legal and illegal immigrants) are less likely to commit crimes than the native-born.” It’s an important fact to consider as other states look to copy Arizona’s tough new law against illegal immigration, which was in large part motivated by fears of crime.

The latest bulletin is the third in a series Cato plans to publish through 2010 and into 2011. The May issue analyzed the pluses and minuses of a Senate Democratic proposal to reform U.S. immigration law, and the April issue critiqued efforts to impose a national ID card and the E-Verify system.
