The purpose of this study is to identify the components affecting the social classes of citizens on urban body design. For this purpose, the theoretical foundations related to social classes and urban body design were examined and the initial conceptual model that included effective indicators was extracted. In the next step, the effective components have been refined by fuzzy Delphi method and using the opinion of relevant experts and professors, and thus more than twenty indicators were removed from the set of identified indicators. The final model includes three main components including physical, social and environmental quality components and seventeen subindicators. Physical component indicators include density and compression, road network, public spaces and milestones, mixing of uses and functions and Urban infrastructure is more important than other components. Indicators of social dimension also include social interactions, job type, income level, level of specialization, education and level of education, family background and social status, identity and sense of belonging, variety of personal tastes and contradictions, and the degree to which social wealth is achieved..

Immigration and the growth of metropolitan areas are always associated with major changes in the areas around them. National Tehran metropolis with its rapid growth in recent decades has caused population increase and physical development of the surrounding towns and villages. The aim of this study is to investigate the factors affecting demographic and physical changes in Garachak city as a settlement around Tehran metropolis. The research method is descriptive-analytic and data collection was based on library documents, observation, in-depth interviews and 300 household questionnaires completed randomly. The data were analyzed by using single T- test, multi-variable regression, interpretation of satellite images (in years 1987 and 2011), and Holdern model. The results showed that due to reasons such as locating on Tehran-Varamin road, short distance and the rapid access to metropolis ​​Tehran and its facilities, and also due to the low costs of land and housing in that area, Garachak city has had high population growth so that the city as a complementary area for Tehran has an additional role in residency and settlement. According to Holdern model analysis, approximately %68 of physical growth and nearly %32 of growth in Garachak city is respectively associated with population growth and horizontal-sprawl growth which have caused huge changes in economic, social, and ecological aspects of the city.
