This research paper examines the rising development in urban social infrastructure in MMR (Mumbai metropolitan region), India. Contrasting the other planned metropolis of India, MMR was distinctively built as a planned transference of a huge urban city. The study centres on explaining the urban social infrastructure of this specific case study. An urban social infrastructure reflects the social attributes of the urban setting. In the instance of MMR, the government had a social agenda to encourage a social form based on socioeconomic division rather than an cultural one. Investigation of the data gives an insight to the result of this social agenda, and presents a basis to frame new ones. The study includes a broad review of secondary source data to create the speculative framework for the research. The review also involves an extensive inspection of the past, present and future of the whole MMR (Mumbai metropolitan region) to better understand the whole context of urban morphology and social infrastructure as a whole and also there effects, pros and cons. The research puts forth a study that explains the social infrastructure of MMR by social area investigation using variables, which are found from social aspects of any big city and native/radical factors of Indian settlements. The study depends not only on form and space analysis but also on understanding of local conditions. As the local conditions of working, living, the geographical factors all widely affect the social infrastructure of the city. This research lays the understanding of the rising social patterns in in developing cities.
