This research has been conducted in the field of urban sociology entitled " The analysis of women’ s sense of Security in the North and South parts of Tehran". This paper, using the theoretical framework, attempts to test sociological theories in the context of Tehran's citizenship as well as revealing differences in the upper and lower regions of the city in enjoying a sense of security and shows that the processes of everyday life of women in the south of the city have been disturbed due to their lack of security. The present study is a quantitative research group conducted in Tehran in 1397. The statistical population of the study consisted of all 18 to 45 year old women in Tehran in northern and southern parts of Tehran. According to the year 1396, their number was 2036680 people. The sample size was equal to 800 women in urban areas of 1, 2, 3, 4, 5, 6, 7, 8, 15, 16, 17, 18, 19, 20 and 22 of Tehran, using sampling technique A multi-stage cluster was selected. The data gathering tool was a researcher-made questionnaire, which was verified using formal, content and structure validity, and its reliability was confirmed by Cronbach's alpha coefficient. After collecting data by scrolling method, the concept of security was first measured in four areas of psychological, financial, emotional and communication security and then, the research hypotheses were analyzed using independent t-test, Pearson correlation and variance analysis. Then, using multiple regression analysis, the effect of each independent variable on the women's sense of safety was transmitted through the urban area. The results of the study showed that the sense of security of women in general and in the four dimensions mentioned in the north of the city is much higher than that of women in the south of the city; There was also a significant relationship between economic conditions, security apparatus performance, social networking network, lack of supervisor, age, marital status and economic status, however, there is not a meaningful relation between the employment status of women and their level of education. This process was performed using Spss. Also, for testing the selected analytical model, the Amos software version 25 was used and the results indicate the fit of the model. The results of this research show that women's security in Tehran is not in a good condition and these results are consistent with the sociological theories used.
