Places Most Unsettled by Rapid Demographic Change Are Drawn to Donald Trump

ARCADIA, Wis.””Small towns in the Midwest have diversified more quickly than almost any part of the U.S. since the start of an immigration wave at the beginning of this century. The resulting cultural changes appear to be moving the political needle.

A Wall Street Journal analysis of census data shows that counties in a distinct cluster of Midwestern states””Iowa, Indiana, Wisconsin, Illinois and Minnesota””saw among the fastest influxes of nonwhite residents of anywhere in the U.S. between 2000 and 2015. Hundreds of cities long dominated by white residents got a burst of Latino newcomers who migrated from Central America or uprooted from California and Texas.

That shift helps explain the emergence of Republican presidential nominee Donald Trump as a political force, and signals that tensions over immigration will likely outlive his candidacy. Among GOP voters in this year’s presidential primaries, counties that diversified rapidly were more likely to vote for the New York businessman, the Journal’s analysis shows.
