The Spatial Scale and Spatial Configuration of Residential Settlement: Measuring Segregation in the Postbellum South1

Studies of residential segregation typically focus on its degree without questioning its scale and configuration. The authors study southern cities in 1880 to emphasize the salience of these spatial dimensions. Distance-based and sequence indices can reflect spatial patterns but with some limitations, while geocoded 100% population data make possible more informative measures. One improvement is flexibility in spatial scale, ranging from adjacent buildings to whole districts of the city. Another is the ability to map patterns in fine detail. In southern cities the authors find qualitatively distinct configurations that include not only black “neighborhoods” as usually imagined but also backyard housing, alley housing, and side streets that were predominantly black. These configurations represent the sort of symbolic boundaries recognized by urban ethnographers. By mapping residential configurations and interpreting them in light of historical accounts, the authors intend to capture meanings that are too o...
