President Donald Trump justifies his hard-line immigration policies by repeatedly claiming, without evidence, that undocumented immigrants are bringing waves of crime into the United States.

Just last week, Trump declared during a Florida rally that an “invasion” of immigrants were bringing in an “unbelievable” amount of crime. He has referred to Mexican immigrants as drug dealers and rapists, and asserts that his long-promised border wall would “MAKE AMERICA SAFE AGAIN.”

But a new, first-of-its-kind analysis debunks the president’s argument. According to its findings, published by The New York Times on Monday, growth in illegal immigration in a particular area has not resulted in higher local crime rates.
