In this study, using the Network Analysis, the topic of Development and Underdevelopment in Iran, has been studied, with Historical-Experimental Approach and using Secondary Analysis of Empirical Findings. This study is based on analysis of some National Surveys, particular, a National Survey on Iranians Cultural Behaviors and two National Surveys on Iranians Values ​​and Attitudes, which have been conducted, respectively, in the years 1999, 2000 and 2003. Overall, our findings suggest that there are relationships between variables of Social Capital, Social Development. Our assumption in this study was that Lack of Social Capital has led to Lack of Social Development, and this phenomenon, in turn, can play an important role in Underdevelopment of Society. These findings suggest that in terms of some important elements of Social Development, such as Trust in Social Groups, Social Participation, Commitment to the Social Values ​​and Norms, Belonging to National Identity and Culture in Iranian Society, the situation is not desirable. In our opinion, the lack of Social Development would lead to Underdevelopment of Society. Consequently, if we want to achieve the goal of Comprehensive Development of Society, we should provide required backgrounds to increase the levels of Social Capital, and consequently, Social Development.
