Maputo is situated on a large natural bay on the Indian Ocean, near where the rivers Tembe, Mbuluzi, Matola and Infulene converge. The city consists of seven administrative divisions, which are each subdivided into quarters or ''bairros''. The city is surrounded by Maputo Province, but is administered as a self-contained, separate province since 1998. Maputo City is the geographically smallest and most densely populated province in Mozambique. Maputo is a cosmopolitan city, with Bantu, Tsonga languages being more common, Portuguese, and, to a lesser extent, Arabic, Indian, and Chinese languages and cultures present.
