Dhaka District (Bengali:ঢাকা জেলা, Dhaka Jela also Dhaka Zila) is a district located in central Bangladesh, and is the densest district in the nation. It is a part of the Dhaka Division. Dhaka, the capital of Bangladesh, rests on the eastern banks of the Buriganga River which flows from the Turag to the south of the district. While Dhaka (city corporation) occupies only about a fifth of the area of Dhaka district, it is the economic, political and cultural center of the district and the country as a whole. Dhaka District is an administrative entity, and like many other cities, it does not cover the modern conurbation which is Greater Dhaka, which has spilled into neighboring districts, nor does the conurbation cover the whole district, as there are rural areas within the district.
