” In 1980, nearly half of U.S. counties — 1,412 of them — had populations that were almost exclusively (98 percent or more) white. Thirty years later, only 149 counties — fewer than five percent — fit that same description. The maps below chart this transformation, decade by decade.
It’s no secret that America is becoming less white. According to Brookings Institution demographer William Frey, whites are on track to lose their majority status by 2042 or thereabouts. Driving this trend are immigration and intermarriage: the white share of the population is projected to shrink by 6 percent between 2010 and 2050. But the Hispanic population will grow by 102 percent, and the share of people identifying as two or more races will see a nearly 200 percent increase. The broad contours of these trends are outlined in a short video produced by Brookings.”
