Introduction: The study of social capital in society is doubly important in terms of its impact on various economic, political and social factors. The reason for naming the central areas - the outskirts of the city of Khorramabad is in fact a problem that has plagued the city. Among the suburbs of non-immigrant immigrants in these areas, the lack of financial-professional capacity of individuals and the lack of a conventional urban culture that is necessary for urbanization have played a role in reducing the sense of security and social capital. The purpose of this study is to examine the social capital - the sense of security among the marginal-central areas of Khorramabad.
Method: The present study is an applied research in terms of descriptive and correlational research method. To conduct a research from a statistical population of 347872 people, the sample size was determined through Morgan formula and 384 questionnaires were prepared and the questionnaire was distributed as a multi-stage cluster in the suburban-central areas of the city and analyzed using SPSS software.
Findings: The results of t-test in two independent samples showed that there is a significant difference between the average social capital in the suburbs of Khorramabad city center. In other words, social capital was not the same in the two statistical groups and was different. The results showed a high average social capital (3.96) feeling of security and a significant difference between these two variables in the central areas of Khorramabad compared to the suburbs.
Conclusion: In the present study, the total average of social capital among the residents of the city center (3.96) was higher than the suburban centers. Regarding other components of social capital, except for social cohesion (4.60), social relations (4.80), the average of most components of social capital among the residents of the city center was higher than the marginalized.
