In 2018, about fifty-five percent of the world's population lived in urban areas and is projected to increase to sixty-eight percent by 2050. The increasing population of cities emphasizes the optimal use of urban neighborhoods for housing. Urban morphology is one of the topics related to the population of neighborhoods. The purpose of this study is to identify morphological indices in the middle scale and explain the relationship between morphology of residential areas and the population living in them. First, based on the internal-cognitive approach, the opinions of thinkers in the field of morphology were examined and the criteria of "land use diversity", "road network pattern", "compaction" and "public transportation network pattern" were identified in 9 indicators on a local scale. Then, the indicators were measured by space layout and network analysis by Depthmap10 and GIS software in 12 neighborhoods of Tehran. In the next step, first the normality of the data was checked by Kolmogorov-Smirnov test method and the correlation of morphological variables with the population index of the neighborhoods was evaluated by Pearson two-way correlation method and SPSS16 software. The results show that the interconnection index with an intensity of 0.724 has the highest correlation and access to public transportation with an intensity of 0.578 has the lowest correlation with the population index. Examining the severity of correlations provides an opportunity for better prioritization to intervene in the existing fabric of neighborhoods with the aim of resettling the population. The results can be used in the field of evaluation criteria for residential design options, selection of road network and quantitative and qualitative assessment of preparation plans in order to accommodate more population and setting the criteria for detailed plans.

Social sustainability is a subject that has attracted the attentions of researchers since the early years of 21st century. Social, economic, and ecological sustainability are considered as the three components of urban sustainable development. On the other hand, the urban form, as an important component of the city comprises communication networks, public transportation systems, pedestrian and bicycle accesses, spatial structures, spatial distribution of activities, housing and settlement size, natural phenomena and non-spatial aspects which all are important for studying and analyzing a city from different viewpoints. Considering the interdependence of the components of this concept with different dimensions of the city, its role on different aspects of sustainability, including social sustainability, would be indisputable. The emergence of urban sustainable development concept pushed the international NGOs and planners to introduce new frameworks for redesigning and reorganizing of cities in order to achieve the sustainability. A critical review of these approaches suggests a disagreement upon the most desirable form of urban sustainability. Social sustainability, due to its intangible nature as well as its focus of mankind and his interactions is subject for such contradictions. The present study was seeking to explain the relationships between the components of urban form and social sustainability in 22 districts of Tehran using a descriptive-analytic research method. Quantitative models such as factor analysis and linear regression as well as resident’s questionnaire (2200 questionnaires were completed among 22 districts of the city) and SPSS software helped the researchers to navigate this route. The findings of the present research showed that there is a significant relationship between the main factors of urban form and the factor of combined social sustainability indicators in all 22 districts of Tehran. Social sustainability indicators included citizen’s access to local services, social security, participation rates in social and group activities, interaction with other residents or social groups, residence satisfaction, and access to affordable housing for citizens. It was also determined that districts 5 and 6 had the highest scores in terms of social sustainability in Tehran.
