Meanwhile, large metro areas like Los Angeles and Houston are seeing a drop in their immigrant populations, writes Nate Berg:
"Of the largest 100 metropolitan areas in the U.S., 47 saw increases in their foreign-born populations of at least 50 percent since 2000. And as those numbers grow and spread, it's increasingly the suburban areas of large metros that are absorbing the growth. Of the top 95 metropolitan areas, the suburbs of 70 are home to more than half of their foreign-born populations."
A map showing the spread is available at The Atlantic Cities.
