Cities VI: Dispos-a-city: Unchecked abandonment off our older cities for sprawling Sunbelt suburb-cities will have a major impact on the urban future

Something of major import is happening to cities in the United States — something that overrides strictly technological considerations and makes a mockery of the best-intentioned plans of urbanologists and systems experts. No consideration of the city of the future can be meaningful without a hard look at what amounts to an urban revolution: the movement of people away from the old and toward the new, and the migration of people from the northeast and central cities toward southern and western ones.
