Beauty is among the most sublime human needs. Since the time humans began building cities, they have paid attention to the sense of aesthetics. The purpose of this research is to conduct a comparative evaluation of two neighborhoods, Golestan and Moradab, as the two most well-off and least well-off neighborhoods in Karaj city, in terms of the aesthetic indicators of urban space. The research method is descriptive-analytical and data collection on 14 selected components related to the aesthetics of the urban environment was carried out by direct observation and using an evaluation checklist. Descriptive statistics parameters were used to analyze and compare the aesthetic level of the two neighborhoods, and zoning maps were drawn in the geographic information system and calculations and analysis were performed on the relevant descriptive tables to analyze spatial inequalities. Considering the evaluation of the indicators in the range of 1-10 points and assigning a higher point to a higher level of aesthetics, the findings showed that the average figure of the total indicators in Golestan neighborhood is 6.31 and in Moradab neighborhood is 2.57. Also, in Golestan neighborhood, the median figure is 6.43 and the first quartile figure is 4, while in Moradab neighborhood these figures are 1.78 and 1, respectively. Spatial analysis of the zoning map showed that in Golestan neighborhood, in terms of total indicators, there are no areas that are at the "very low" and "low" levels in terms of aesthetics, while in Mardab neighborhood, there are no areas at the "high" and "medium-high" levels. It can be concluded that Golestan neighborhood is at a high level in terms of aesthetic indicators and there is a lot of spatial inequality within and between the two studied neighborhoods.
