Special police
In the People's Republic of Bangladesh, there are eleven metropolitan areas: Dhaka North, Dhaka South, Gazipur, Chittagong, Rajshahi, Khulna, Sylhet, Barisal, and Rangpur. Lands are highly priced and residents are considered to have a better urban lifestyle. Special police departments are allotted for the metropolitan cities, and there are city corporations for which mayors are elected for five-year regimes. Most of these cities have population density of 35,000/square mile or more. Dhaka is the wealthiest city out of all of them and is considered a Megacity because its population surpassed 10 million.
