Population Analysis of a Residential Area in Yotsuya in Tokyo

Abstract

This area had been known as a typical low-class workers' area before the War. It is located at the bottom of a valley cutting the margin of the upland of Tokyo. The total population of this area is 4, 103 in 1940 and the ratio of semiskilled and unskilled workers was 72.5% in man and 75.4% in women. 73.7% of them are working in the urban center. In the “Population Pyramid” some characteristics are to be observed: First of all, the age group of 21-22 years is missing, secondly as is shown in black, the workers working outside this area are mainly men of all age groups and women of age groups 18-21 and 40-55 years. Thirdly, the population in productive age is not in excess in spite of the fact that this is a workers' residential area.
