Maps of segregation often highlight concentration patterns of racial or ethnic groups. Patterns at the edges of the segregated areas are not typically shown or discussed in many of these maps. The lack of attention to the edges—transition areas—may be because it is assumed that segregated areas change abruptly from one racial group to another. Exhibit 1, however, as an example, reveals patterns of racial integration that form at the edges and outline the boundaries of the segregated areas in Chicago.
