Social diversity in the neighborhood districts has been the new approach for the challenges resulting from varieties in cities. Social interpreters of this policy are to create neighborhoods where people of different ages, ethnic-racial backgrounds, income, etc. take a place in it. In this regard, many designers by using the concept of different forms of ownership such as housing schemas, different types of constructing and housing etc. have tried to promote it. Due to the less interest that came toward this issue, the knowledge of this mechanism is poor in urban ecology of Iran. The aim of this study is to assess the effects of urban design in promoting the social mixing which is determined with the research of the Abadan community areas. Relevant parameters have been studied with library studies, field visits and by the use of qualitative and quantitative analytical methods. Therefore, after reviewing the relevant concepts, we are going to test hypotheses by the exامینation of case studies, and finally, the influences of urban design criteria are presented.
