Does deporting undocumented immigrants reduce crime?

No. Deporting undocumented immigrants does not reduce crime. We believe this is the best available short answer based on our reading of the 4 studies we found that examine this question. However, we believe this question is underresearched. Additional study may change our conclusion.

The 4 studies were published from 2007 to 2014. All of them focused on the United States of America. Evidence from three of the studies supports this answer. One other study reached mixed conclusions.

Although we recommend you consider all of the studies below, the study that we believe has examined this question in the most comprehensive way is: Does Immigration Enforcement Reduce Crime? Evidence from “Secure Communities".

Keep in mind that we strive to only include studies that directly address this question. Evidence from studies focusing on other questions may indirectly support or undermine our conclusion.
