This spurt of suburban expansion, however, does not alter the basic fact that the United States has become one of the most urban nations on the face of the earth. Census (人口调查) Bureau figures show that the rural population has been shrinking steadily since 1830. When the United States became a nation it had no large cities at all; today some fifty cities have populations of more than 258 ,000. Mammoth complexes of cities are developing in the area of the East Coast and the east north-central states, on the Pacific and Gulf coasts, and near the shores of the Great Lakes. Some sociologists now regard the entire 600-mile stretch between Boston and Washington, D. C.—an area holding a fifth of the country' s population—as one vast city or, as they call it, megalopolis.
