In fact, the study from sociology professor Michael Light found that increases in undocumented immigration were associated with a heavy drop in violent crime.
“Since 1990, the undocumented immigrant population in the United States has tripled. It’s part of the largest wave of immigration the country has ever experienced,” Light said. “In that same time, the violent crime rate has halved.”
Light says his results may be partially explained by the socioeconomic factors that bring undocumented immigrants to the U.S.

Light’s study comes at a tumultuous time in the U.S. in regards to immigration, with President Donald Trump calling for the creation of a border wall between the U.S. and Mexico to keep out undocumented immigrants, who, according to Trump, bring “drugs and crime.”
Even though the debate has received significant publicity in recent years, little research has looked at crime’s relationship with undocumented communities specifically.
“This is one of those rare areas everyone is talking about, but the conversations are occurring in a vacuum of data,” Light said. “A lot of research has looked at immigration and crime, but most of those conversations have been limited to the overall foreign-born population or the Latino foreign-born population, not the undocumented population.”
With new data in hand, Light says his findings are straightforward.
“The direction of the relationship is fairly clear,” he said. “They’re all negative.”
