United States

The metropolitanization of life in the United States has not been limited to city, suburb, or exurb; it now involves most of the rural area and population. The result has been the decline of local crafts and regional peculiarities, quite visibly in such items as farm implements, fencing, silos, and housing and in commodities such as clothing or bread. In many ways, the countryside is now economically dependent on the city.

The city dweller is the dominant consumer for products other than those of field, quarry, or lumber mill; and city location tends to determine patterns of rural economy rather than the reverse. During weekends and the vacation seasons, swarms of city folk stream out to second homes in the countryside and to campgrounds, ski runs, beaches, boating areas, or hunting and fishing tracts. For many large rural areas, recreation is the principal source of income and employment; and such areas as northern New England and upstate New York have become playgrounds and sylvan refuges for many urban residents.

The larger cities reach far into the countryside for their vital supplies of water and energy. There is an increasing reliance upon distant coalfields to provide fuel for electrical power plants, and cities have gone far afield in seeking out rural disposal sites for their ever-growing volumes of garbage.

The majority of the rural population now lives within daily commuting range of a sizable city. This enables many farm residents to operate their farms while, at the same time, working part- or full-time at a city job, and it thus helps to prevent the drastic decline in rural population that has occurred in remoter parts of the country. Similarly, many small towns within the shadow of a metropolis, with fewer and fewer farmers to service, have become dormitory satellites, serving residents from nearby cities and suburbs.

Urban settlement

The United States has moved from a predominantly rural settlement into an urban society. In so doing, it has followed the general path that other advanced nations have traveled and one along which developing nations have begun to hasten. More than four-fifths of the population lives clustered within officially designated urban places and urbanized areas, which account for less than 2 percent of the national territory. At least another 15 percent live in dispersed residences that are actually urban in economic or social orientation.

Classic patterns of siting and growth

Although more than 95 percent of the population was rural during the colonial period and for the first years of independence, cities were crucial elements in the settlement system from the earliest days. Boston; New Amsterdam (New York City); Jamestown, Virginia; Charleston, South Carolina; and Philadelphia were founded at the same time as the colonies they served. Like nearly all other North American colonial towns of consequence, they were ocean ports. Until at least the beginning of the 20th century the historical geography of U.S. cities was intimately related with that of successive transportation systems. The location of successful cities with respect to the areas they served, as well as their internal structure, was determined largely by the nature of these systems.

The colonial cities acted as funnels for the collection and shipment of farm and forest products and other raw materials from the interior to trading partners in Europe, the Caribbean, or Africa and for the return flow of manufactured goods and other locally scarce items, as well as immigrants. Such cities were essentially marts and warehouses, and only minimal attention was given to social, military, educational, or religious functions. The inadequacy and high cost of overland traffic dictated sites along major ocean embayments or river estuaries; the only pre-1800 nonports worthy of notice were Lancaster and York, both in Pennsylvania, and Williamsburg, Virginia. With the populating of the interior and the spread of a system of canals and improved roads, such new cities as Pittsburgh, Pennsylvania; Cincinnati, Ohio; Buffalo, New York; and St. Louis, Missouri, mushroomed at junctures between various routes or at which modes of transport were changed. Older ocean ports, such as New Castle, Delaware; Newport, Rhode Island; Charleston, South Carolina; Savannah, Georgia; and Portland, Maine, whose locations prevented them from serving large hinterlands, tended to stagnate.
