Segregation Landscape : A new view on the Schelling segregation space

Abstract : Thomas C. Schelling showed that global aggregation may occur, even if it does not correspond to agent preferences; thus, to some extent his model supported the view that segregation is unavoidable, whatever the tolerance is. The segregation landscape approach proposed in this paper is seriously weakening this hypothesis; here, we radically change the perspective and propose using the landscape metaphor to represent emergent segregated communities. A segregation landscape is a mapping from situated individuals into an extra dimension which represents the degree of segregation of everyone. This paper uncovers how to interpret hills and valleys, and whether these interpretations are congruent with the intuitive notion of frontier. Such a representation allows to describe both the static properties of a segregation space as well their impact on how does information propagate between segregated communities. In order to assess the explanatory power of the landscape metaphor, we devise agent-based simulations. First, we establish the link between the micro-level quanti ed by individual tolerance and the macro-structure represented by the landscape; then we show how "geographic" properties impact the dynamical behavior on such a population landscape.
