The urban built environment has a significant role in leading individuals to outdoor spaces, socializing, and being together. Despite the Egyptian Government’s efforts to provide more housing for people in different forms, they ignore the social life in the new residential neighborhood when designing the neighborhood’s urban form. This paper examines the quantitative connection between the Urban Form Aspects and Social Sustainability in residential communities. The research selects Salam New City in Port Said Governorate as a case study and applies different scenarios for the most important urban aspects. The research uses the simulation method to investigate the effects of the different urban form scenarios on the social aspects by using Urban Modeling Interference (Umi) and DepthmapX simulation software. Finally, the paper concludes that social interaction and activities improve by 48% and social integration will improve by 74% from the base case for Salam New City case study when using the Urban Form Aspects (Green percentage 35%, Mixed land use 40%, Street network 7% with D/H Ratio 4/1), which leads to improving the social life in the selected area.
