Extended abstract: Evaluation of relationship between density and social sustainability in Tehran Municipality’s regions

Extended abstract1- Introduction Issue of sustainable development and especially sustainable urban development has been one of the most important concerns of policy makers and planners since the Rio Conference. This point of view was given form environmental, economic, managerial and social comments that have collected from all fields of university studies about cities. With assuming “compact city form” as the stable urban form and also regarding to prevent suburbs spread of Tehran metropolis subject entitled as “organizing and protecting the city’s boundary and preventing any spread of span area”, the various aspects of Tehran sustainability, according to the characteristics of compact city, is necessary to study. Issue of social stability in the compact city model has become a challenging subject among researchers and planners. Some of them believe that if cities become more dense then social stability decreases. But others argue that denser cities have more social stable positions. To sale building density as a one of the most important sources of income for Tehran Municipality became rampant during the decade of nineties. This change has had different effects to urban region. This has various impacts on increase of pollution, low standard of urban services, traffic problems and disturb of social coherence. So research and explore with literature review attentions in Tehran city with real data will be the best way for understanding of density's decrement affects. Clearly, compact city and sustainability are from western theoretical achievements and not related to Iranian cities. But using of these theories is the way to find Iranian theories about affect of densities to social sustainability. And it will show that how much different is between western and Iranian cities from point of views and theoretical achievements. 2- MethodologyDue to the necessity and importance of social stability in Tehran metropolitan and also according to its planned vision, this study discussed about the social stability in various area of Tehran. In addition, social stability level in some regions with different population density are investigated and analyzed. This study is not pursuing to establish relationship between density and social stability. Also, factor analysis was used for defining of primary factors of the research and expert's comments and factors' load were used for naming these new factors. Library studies and statistics collects, building an analytic model and indexes, using of experts for finalizing analytic model, statistics analysis and mathematical cal
