One way to achieve sustainable urban development is to provide the facilities and services needed by citizens living in urban areas. Balanced spatial organization in cities is a form of urban sustainability and will be achieved when there is logical coordination and compatibility between population distribution and service distribution in cities. This research aimed to evaluate the degree of success in providing urban services based on the level of citizen satisfaction (case study of Region 4 of Ahvaz). The present study, based on the nature of the subject and the goals foreseen for it, is of a descriptive, analytical type and is classified as applied research. SPSS software was used to analyze the data, and the one-sample T-test, Pearson's correlation coefficient, and the variance inequality test were used to evaluate the desired indicators to test the hypotheses The results of the findings show that the urban furniture index with an average of (1.26), the environmental index with an average of (1.13), and the urban furniture index with an average of (1.12) were significantly lower than the expected average (3). This indicates a lack of proper provision of services, which has led to dissatisfaction among the residents of the studied area. The results of the Pearson correlation test also showed that there was no significant difference between the three indicators and that this region was suffering from all aspects (poor urban services and very low satisfaction). The analysis of variance inequality test (Anova) also confirmed the results of the one-sample T-test.
