The data consistently show that U.S.-born individuals are more likely to commit homicide than undocumented immigrants.

Research from the Cato Institute and a study published in the Proceedings of the National Academy of Sciences suggest that U.S.-born individuals commit homicide at higher rates than undocumented individuals. 

The study in the Proceedings of the National Academy of Sciences also found that between 2012 and 2018, U.S.-born citizens were twice as likely to be arrested for violent crimes as undocumented immigrants in Texas.    

Research from the Marshall Project in 2019 found that increases in the number of undocumented immigrants did not lead to more violent crime.
