Introduction
Residential satisfaction is one of the main topics in which the urban researchers are interested. Residents' assessment of the quality of their residential environment is effective in measuring the achievement of the goals and the success of the urban projects. According to the 2016 statistics, more than 54 percent of the world's population lives in cities. The urban residential environment has become the main habitat for the people around the world. According to the country’s census in 2016, over 59 million people live in cities. With respect to the increasing urbanization and the high rate of changes in urban texture due to various reasons, the quality of residential environment in urban areas has been severely reduced. Therefore, in order to continue the urban life by satisfying the minimum human needs, it is necessary to pay attention to the urban environment quality and the citizens' satisfaction from the quality of their habitat. Therefore, as the small towns have their own specific features and environments; it is important to evaluate the quality of these environments to reflect in the degree of satisfaction.

We try to answer the following two questions: A) what is the degree of the satisfaction from residential environment quality in Zarghan? B) Which indices of satisfaction from the residential environment quality have the greatest effect on the citizens’ willingness to reside in this town in the future? It is noteworthy that the theoretical approaches to the residential environment quality can be divided into the following categories of A) The physical design and B) social-spatial approaches including human ecology, quality of life, social and interactive indices, and assessment of the degree of residential satisfaction. According to the objectives of the approach, the degree of satisfaction has been selected as the theoretical approach in this study.
