Trump exaggerates the link between immigration and crime; almost all research shows legal and illegal immigrants are less likely to commit crimes than the native-born population.
In general, economists say illegal immigration tends to affect less-educated and low-skilled American workers the most, which disproportionately encompasses black men and recently arrived, low-educated legal immigrants, including Latinos.
The consensus among economic research studies is that the impact of immigration is primarily a net positive for the U.S. economy and to workers overall, especially over the long term. According to a comprehensive 2016 report by the National Academies of Sciences, Engineering, and Medicine on the economic impacts of the U.S. immigration system, studies on the impact of immigration showed “the seemingly paradoxical result that although larger immigration flows may generate higher rates of unemployment in some sectors, overall, the rate of unemployment for native workers declines.”
