Suburbs

The suburbs of the 140 metropolitan districts defined by the Sixteenth Census are analyzed in this paper. These suburbs have a population of 22,369,432, or 35.5 per cent of the population of the districts and 17.0 per cent of the population of the entire country. In 10 metropolitan districts more than 60 per cent of the people live in suburbs. The extent of development of suburbs varies according to functional type and size of city, location with respect to a climax area, and location with respect to rivers and associated state boundaries. Of the 352 individual suburbs of more than 10,000 population classified in this paper, 174 are residential and 149 industrial. Generalized suburb types including the whole suburban area of each district have also been evolved. These suburb types, indicated by letters are: A, industrial fringe; B, industrial; C, complex; D, dormitory; and E, mining and industry. Although suburban development has been closely associated with industry suburbs stagnated during the last decade, whereas residential suburbs showed rapid growth.
