Therefore, in this study, the aim is to measure the performance of urban management on the quality of life of informal settlements in Miandoab City. The research is descriptive-analytical in terms of method and nature and is one of the in-depth and quantitative researches. Data were collected from both library and field methods through a questionnaire. The validity of the questionnaire was confirmed by the elite community (10 people) and its reliability was calculated with Cronbach's alpha greater than 0.79. The statistical population of the study consists of citizens living in 10 informal settlements of Miandoab city, 11545 people. The sample size was 313 based on Cochran's formula. The result of one-sample t-test showed that the urban management index is significantly less than 0.05. The average difference of -1.403 confirmed that the urban management index for informal settlements in Miandoab is weak. Also, the regression model indicates the effectiveness of the urban management index in improving the quality of life of informal settlements with a coefficient of 0.901. The participation variable with 23% and the cleaning and environmental health variable with 11% predict the most and the least impact on improving the quality of life, respectively. Therefore, the existence of an integrated urban management consisting of people and officials with emphasis on participation-oriented and structural indicators can help improve the quality of life of neighborhoods.
