title: Changing urban populations: regional restructuring, racial polarization, and poverty concentration.
abstract: This study examines the changing profile of the urban United States, with particular reference to the impact of immigration, suburbanization, and growing diversity associated with increased racial and income polarization. "This overview provides a backdrop by focusing on the forces that shape key demographic trends across broad regions and in metropolitan areas and then shows how these trends have led to disparities in growth and decline, racial polarization, and poverty concentration."
