摘要

Traditional urban study models, which emphasize the roles of transportation and industry in defining the city's growth, are tested by using centrographic techniques to analyze the growth of Atlanta, Ga., since World War II (1940 - 1975). Centrographic techniques map changes as functions of location, shape, and dispersion. The bulk of this highly theoretical discussion consists of maps tracing the changes in Atlanta's total population, its black population, income distribution, housing, mobility of population, and employment. Traditional theory assumes that a city grows outward from a central ring and that newcomers increase the density of the central city by converting the homes of the wealthy into tenaments. In Atlanta, newcomers settled in housing developments around the edge of the city. These developments displaced lower - income and moderate - income fringe residents, who were dispersed even further. Industries also developed on the edge of the city, commuting times lengthened, and transportation decreased as an important consideration in housing and employment location. The black population grew rapidly, concentrating in a single section of the city on an east - west axis running through the central business district. This vector of growth was at more than a 90 degree angle to the vector of growth for the region, removing blacks from new job opportunities. These and other complexities of urban behavior, not explained by current models suggest the need for new theories. Extensive notes and references are appended.
