Abstract :

Urban segregation is a significant issue in many cities around the world, and researchers have paid special attention to it for decades. Urban segregation often results in the concentration of poverty, the unfair allocation of resources, opportunities, and urban facilities, ultimately leading to conflicts and social crises within the city. The aim of this study is to assess the spatial–physical and infrastructural segregation in the metropolis of Tehran. This research employs a quantitative method with a descriptive–analytical approach. To this end, the level of spatial–physical and infrastructural segregation in Tehran was first measured using a segregation analysis software. Subsequently, the spatial structure of the metropolis was analyzed based on the mentioned indicators. The results indicated that the distribution of physical and infrastructural indicators in Tehran reveals a range of segregation levels—from low to high—among the city’s 22 districts. The spatial structure analysis of segregation showed a trend toward centralization in the physical and infrastructural segregation of Tehran. Moreover, some indicators demonstrated tendencies toward the northern axis (comfort and convenience, internet access, and access to public parks) and the southern axis (building age) of the city. Additionally, using Geographically Weighted Regression (GWR) to explore the relationship between the spatial distribution of the population and the physical–infrastructural indicators of Tehran, it was found that indicators such as access to urban parks, access to the gas network, comfort and convenience, and safety had the most significant impact on the spatial distribution of the population. The spatial distribution and segregation of physical–infrastructural indicators in Tehran display a trend toward centralization and the emergence of a clustering pattern. This may lead to a pronounced concentration of these indicators among Tehran’s districts in the coming years.
