The ethnic map of U.S. cities has drastically changed in the last decade, which could affect how major metropolitan areas provide social, educational and health services, according to a study released by the Brookings Institution.


Nonwhite people and Hispanics accounted for 98 percent of the population growth in metropolitan areas from 2000 to 2010, Brookings found in its analysis of the 2010 U.S. Census.


By 2010, minorities made up more than half the population in 22 of the 100 largest metro areas, it said. That compares with 14 areas in 2000 and five in 1990.


“Overall, most of these ‘majority minority’ metro areas are located in California and Texas, where Hispanics dominate the minority population,” Brookings said.


The research group found that “diverse Hispanic and Asian communities who speak a variety of languages and represent different origins” are growing in many cities.
