Bhairab Bāzār, Bangladesh

Capital City

This city in central Bangladesh is a crowded, bustling place - the population of 156,293 is crammed into just 15.71 square kilometers, resulting in a population density of over 7,500 people per square kilometer. The literacy rate is a respectable 77.82%, though the bureaucracy of the local Paurashava government is reportedly a persistent headache. Bhairab's status as an important railway junction may appeal to some, but the sheer density and scale of this urban center is not for the faint of heart.
