Introduction: There is an emphasis on human dimension and the community as the main axis of sustainable development. The goal of sustainable development, as considered in this paper, is to explore comprehensive development which is made possible through social development. Objectives such as cultural identity, social cohesive, establishment of public organizations, citizen participation, and empowerment of people are central to this discussion. This paper attempts to contribute to the definition of social sustainability in a comprehensive and coherent manner and develop a theoretical framework within which this concept can be analyzed. There is a shortcoming of this framework in the available literature today since it requires a rearrangement of multidimensional elements. This can combine social, economic and environmental issues into a single independent body.In addition, the concept of "social sustainability" can be observed through a qualitative lens since it deals mainly with qualitative concepts such as human life and well- being. Thus, "social sustainability" preserves and promotes social capital, i.e. realization of a unified and comprehensive society with mutual benefits for all residents, greater interaction between groups of citizens. This is accompanied by greater sense of compassion, patience, flexibility, and affection. Social capital, in this manner, is the values of "human rights" and "cultures". In developing a comprehensive definition of the concept of "social sustainability", we have considered people within their living environment and the physical potential as well as their ability to reproduce the structure. As shown by previous studies, understanding the concept of social sustainability is better achieved by understanding and accepting the importance of other concepts such as "quality of life" and "social welfare". These are evaluated by the criteria such as accessibility to services, decent housing, security, appropriate income, and lower levels of deprivation.
