This district, comprising of the suburbs of Chembur, Mankhurd, Govandi, and Trombay were considered the poorer cousins of the Western and Central Suburbs for various reasons. The rail connectivity was poor. Chembur is home to a chemical factory RCF which used to be but no longer is famous for its pollution. But this reputation has been undergoing a change in the past few years. Bombay has expanded into Navi Mumbai "New Bombay" and the Harbour Suburbs are on the way. Road connectivity has also improved quite a bit.
This area is home to many educational institutes, including the Tata Institute of Social Sciences, International Institute for Population Sciences and many private colleges of engineering. The Bhabha Atomic Research Centre BARC is located in Trombay.
