FACT BRIEF

Do undocumented immigrants commit more crime than native-born Americans?

Recent research suggests that undocumented immigrants have a lower crime rate than native-born American citizens.

Analyzing Texas arrest data between 2012 and 2018, researchers from the University of Wisconsin, Madison found that undocumented immigrants were "roughly half as likely to be arrested for homicide, felonious assault, and sexual assault" compared to native-born citizens. Undocumented immigrants were also significantly less likely to be arrested for drug and property crimes.

In a similar study, Cato Institute found that in 2018, the criminal conviction rate for undocumented immigrants was 45% below that of native-born Americans in Texas.

Consistent with these findings, a 2018 study published in the journal Criminology, which analyzed criminal, socioeconomic, and demographic data from all 50 states and the District of Columbia between 1990 and 2014, concluded that "undocumented immigration does not increase violence," instead observing a negative correlation between undocumented immigration and violent crime.

This fact brief is responsive to conversations such as this one.

Gigafact

Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs.
