This paper discusses the relative lack of the use of sociological and cultural variables in the basic conceptual models of regional science. It presents sociological and cultural additions to classic residential location and land value theory. The augmentation of the topographic physical models and theories of regional science by the explicit introduction of social geography would permit improved land use decisions to be made. Survev or market research techniques are frequently required to identify the key links between the externally observable demographic characteristics of a group and the consumer preferences and behavior information needed to estimate the group's location-specific bidrent function.
