The development of urbanization is one of the most important factors in population concentration,change in environmental conditions , general urban structure change that has caused the development and spread of decay textures conditions and has challenged the sustainability of the city.

The research method is analytical-descriptive and data are collected and the statistical information is analyzed in four dimensions: physical, social, economic, and environmental, using the ELECTRE model and the three regions are ranked based on them. The findings show that District 3 of Tehran 10 area is in the most stable physical condition thanks to the modernization of most of its buildings and having the least amount of microorganisms in the texture and impassable streets. Regarding the social status of District 2 based on the average population, the number of literate students as well as the average environmental indicators, it is considered the most stable socially and environmentally. On the other hand, the number of immigrants is very high in this area and the imbalance in the population and the use of services and green spaces results in economic inefficiencies.
