Rural development is one of the important pillars of national development. Knowledge of the capacity, resources and capabilities of rural areas is an important prerequisite for development planning in these areas. Therefore, the purpose of this study was to determine the coefficient of development of rural villages in the city of Nayer, Ardebil province. The research method is based on objective, cognitive and analytical-based method. The statistical population of the study consisted of 13 villages of over 300 people from among 100 villages in the city of Nayr and indicators used in the research, including social, health, cultural, educational, and. . . indicators. Required data was collected using the Statistical Yearbook of 2011, referring to relevant departments and organizations and field findings. For data analysis, the rural development coefficient model has been used. The findings of the research indicate a large gap between the villages of the city of Nair, in which the villages of Qarashiran, Villaruz and Busjin are more developed than other villages and have higher developmental capability, while other villages have lower developmental capability and investment They will probably be defeated. The results of Pearson correlation test show that the relationship between population and developmental coefficient is high correlation, the higher the village population, the higher the coefficient of development. moreover, the study of the relationship between distance from urban centers and the coefficient of construction indicates a relatively weak correlation between these two factors, so that the proximity of villages to urban centers is relatively weak in their development.
