Abstract
On October in 1965, Japan Housing Corporation made the periodical survey for the residents in JHC housing estates. This report is the short summary of that census. Main emphasis is placed upon the analysis of social stratification of residential families from the time series point of view. Some remarks are stated as follows. 1) Population Structure by age groups is defferent from that of national average. The age group between 25 and 35 takes nearly half of the total population, and 20% is occupied by the age group between 0 up to 4, 10% for 5 to 10 years. 2) This specific character is clearly seen among the residents living in the smaller housing types. Family types belonging to larger housing types are similar to the national average type. 3) As the time of dwelling in these housings becomes longer, this specific character is gradually changed to the nationally average family type. 4) Average family size is 3.41 person per dwelling 70% of all the families are taken by a family type having 3 to 4 person. 5) Average family size observed in 1960 was 3.26. This shows an increase of 0.15 person per family between 1960 and 1965. It is thought that this figure will become reached to the average urban family size within near future. On the contrary, national average of the family size is gradually decreasing. 6) A mono nucleus family type occupies 80-90% of total families. As the housing type become larger, the ratio of "Older family" increases. 7) As time elapses, the ratio of "Older family" increases and this tendency is more clear within the larger housing type. A housing type with more than three bedrooms is occupied uniformely by the different family type. 8) Average monthly in come per family is 70, 000 yen which is 70% higher than 42, 000 yer, the average one in 1960. But the variance of its distribution becomes larger. 9) Average monthly income per person in 4, 000 yen higher than that of average urban family. Living Standard of residents in JHC housing estates is thought to be considerably high.
