"In 136 metro areas, almost 70 percent of those studied, the immigrant population increased between 1980 and 2016 while crime stayed stable or fell. The number of areas where crime and immigration both increased was much lower — 54 areas, slightly more than a quarter of the total. The 10 places with the largest increases in immigrants all had lower levels of crime in 2016 than in 1980."
