Immigrant populations in the United States have been growing fast for decades now. Crime in the same period, however, has moved in the opposite direction, with the national rate of violent crime today well below what it was in 1980.
In a large-scale collaboration by four universities, led by Robert Adelman, a sociologist at the State University of New York at Buffalo, researchers compared immigration rates with crime rates for 200 metropolitan areas over the last several decades. The selected areas included huge urban hubs like New York and smaller manufacturing centers less than a hundredth that size, like Muncie, Ind., and were dispersed geographically across the country.
According to data from the study, a large majority of the areas have many more immigrants today than they did in 1980 and fewer violent crimes. The Marshall Project extended the study’s data up to 2016, showing that crime fell more often than it rose even as immigrant populations grew almost across the board. [Continue reading…]
