The inclusive city approach focuses on vulnerable groups, minorities, deprived and rejected individuals, and calls for justice and the reduction of inequality in various fields. The main goal of this study is to measure and spatial analysis of the Inclusiveness of Tehran Urban spaces to assess the Accessibility of vulnerable groups to urban services. Vulnerable People include women, children, the elderly, the illiterate, the unemployed, immigrants, and families with disabilities who are assessed as target groups. The method used in this research is quantitative and by comparing and validating three different methods of spatial data mining methods Such as principal component analysis, spectral clustering, and self-organizing maps. Validation and evaluation of different options in clustering have been done using 4 internal clustering evaluation indicators and comparison between the best method and the most optimal number of clusters. Results, show the self-organizing maps method and also 5 number of clusters have been selected as the best option from other options. Based on the final outputs, about 31 percent of the residential area in Tehran has a lower than average accessibility, most of which are located in the marginal spaces and near the border of the city. Also, most of the central and northern areas of Tehran have good and very accessible access, which constitutes nearly 40percent of Tehran's residential areas.
