Metropolitan Diversity: Portland, 2000-2010

A ring of diverse suburbs (20 to 60 percent nonwhite) expanded around the Rose City just as it did around many of America's largest metropolitan areas during the first decade of the new century.

In 2000, the predominantly nonwhite suburbs found in many other American cities were not present in the Portland, Ore., metropolitan area. As the area diversified over the next decade, no area became predominantly nonwhite. The greater Portland area's population grew by about 14 percent, to 2.2 million, according to the region's data summary (pdf).
