In 1988 about 18 percent of the population lived in urban areas, most of which were villages or trade centers in rural areas. Urban centers grew in number and population during the 1980s as a result of an administrative decentralization program that featured the creation of upazilas. In appearance these small urban areas were generally shabby. Most of the urban population merely congregated in ramshackle structures with poor sanitation and an almost total lack of modern amenities. Towns were populated mostly by government functionaries, merchants, and other business personnel. Most dwellings contained nuclear families and some extended family lodgers. A few households or a neighborhood would constitute a para, which might develop some cohesiveness but would have no formal leadership structure. With the exception of a small number of transients, most town populations consisted of permanent inhabitants who maintained connections with their ancestral villages through property or family ties. Most towns had social and sporting clubs and libraries. Unlike in the rural areas, kinship ties among the town population were limited and fragile.Rahim, Enayetur. "Urban Society".
