Previous studies of the residential succession process have described the patterns of succession in terms of stages defined either by the responses of the residents or by the percent of black population occupying the area. The present study approaches the investigation from an operational point of view, using a microscopic technique of data collection and analysis. A relatively small area is concentrated on, and the patterns are analyzed in terms of specific dwellings, streets, and blocks. The earlier stages of the succession process are focused on, since they give direction to the later concentrated stage. The area studied is one of the oldest inner-city neighborhoods in Buffalo, New York. Bounded physically by major traffic arteries, parks, schools, and playgrounds, it has all the qualities of a natural area. Over the years it has come to be recognized as an entity displaying both physical as well as psychological boundaries, readily identified by both residents and non-residents alike. (Author/JM)
