Abstract

Tehran Metropolitan Region presents heterogeneous spatial distribution of population in different settlements due to abnormal high growth rates, and migration of different classes with different socio-economic characteristics which has led to socio-spatial segregation and formation of specific spatial structures. Therefore, the main purpose of this study is to examine the impact of socio-spatial segregation of occupational and educational groups on spatial structure of Tehran Metropolitan Region and how this trend changes over the period of 2006-2011 based on morphological approaches. The methodology is quantitative from the viewpoint of the method of research work, descriptive-oriented in terms of purpose and in terms of type, is practical. So, according to the population and housing census data conducted by Statistical Center of Iran in the years 2006 and 2011,3 general methods including the rate of inequality of the social groups were studies using Gini coefficient, Kernel Density method were used in order to analyze how the spatial distribution of aforementioned groups in Tehran Metropolitan region and The relationship between classes contribution of different social groups and Distance of each Spatial unit from the Principal City of Metropolitan Region(Tehran Metropolitan) were analyzed through geographically weighted regression. The result shows that the inequality of occupational and educational classes were lower middle based on Gini coefficient and The Spatial distribution of classes of social groups using the Kernel Density method, demonstrate the transition from monocentric to polycentric spatial structure in some classes of social groups and Geographically weighted regression considering each of Reviewed groups, Indicates a decreasing trend in the rate of impact of their contribution to each of the spatial units by distance from the principal city in most classes.
