Following jobs to rural and suburban areas, in industries like construction and the food business, immigrant populations rose more than 60 percent in places where immigrants made up fewer than 5 percent of the population in 2000. In areas that had been home to the most immigrants, the foreign-born population was flat over that period.
In Los Angeles County, long a major destination for new immigrants, the foreign-born population remained largely unchanged for the first time in several decades. In contrast, it quadrupled in Newton County, in central Georgia outside Atlanta.
