On Roland K. Hawkes's "Spatial Patterning of Urban Population Characteristics"

Comments on Hawkes's ''Spatial Patterning of Urban Population Characteristics,'' (American Journal of Sociology 78: 1216-35, March, 1973) are presented. Specifically discussed are the Hawkes choice of functions, particularly the limitations placed on the radial function, conflict of evidence indicating multiple city centers with the Hawkes assumption of a single center, and the general problem of subdivision of an area and its relationship to continuity of the surface representing a distribution of a characteristic of the area. This commentary generally points out the insufficiency of the Hawkes model. (JWP)
