Segregation measures are useful tools for the analysis of patterns, causes and effects of residential segregation. However, most of empirical segregation studies have employed nonspatial and global measures. In other words, the measures so far applied are unable to consider the spatial arrangement of population and to show how much each areal unit contributes to the segregation degree of the wh...

In this paper, we study social interactions between two populations of individuals living in a city. Agents consume land and benefit from intraand inter-group social interactions. We show that in equilibrium segregation arises: populations get separated in distinct spatial neighborhoods. Twoand three-district urban structures are characterized. For high population ratios or strong intergroup in...

The distributional pattern formation of the populations of two competitive species in heterogeneous environments is analyzed. In the mathematical formulation, a non-linear dispersive force due to mutual interferences of individuals and an environmental potential function are introduced as a behavioral version of Morisita’s phenomenological theory of “Environmental density”. Mathematical analyse...

the theory of urban ecology is based on explaining urban spatial structure, studying and describing the reciprocal relationship between human societies in the urban areas and the environment, as well as analyzing the circumstances of urban population segregation and production of everyday life spaces. to study and explain urban ecological structure of mashhad, the case study of the article, we ...

Social-spatial segregation has been one of the most studied issues within the area of urban studies for nearly one century. The word segregation itself has to do with the idea of the separation of certain social groups within the space of societies. It can be considered as a consequence or manifestation of social relations that are established and based on social structure, stratification, rule...

This paper explores trends in residential segregation, spatial isolation, and poverty concentration for Hispanics and Asians in new, traditional, and low immigration areas. The analysis uses a typology of destination areas derived from an earlier classification scheme developed by Singer (2004). It uses the index of dissimilarity to measure segregation from whites and the P* isolation index to ...
