Mumbai is the capital of the state of Maharashtra in India with an estimated population of 19 million. It has experienced growth through both organic development led by indigenous settlements as well as structured development under colonial British and Portuguese rule when it was designed with a grid system. Over time, Mumbai has developed into a major economic center of India driven by global trade and commerce with the coexistence of areas like the planned region of Navi Mumbai contrasting with the more organic development of Dharavi slum.
