Abstract
This report has two purposes, one of which is to propose the concept of "the ratio of residential mobility", and the method of calculation for its ratio. The second is to examine the factors affecting the mechanism of residential mobility, that is, mainly the characters of the regions and the years of dwellings. The conclusions are as follows, 1) The ratios of mobility are varied among the regions, the tenures, and the years of dwellings. 2) In calculating the ratio of mobility, it is very important to consider the effect by the obsolescence in housing stock and the ratio of vacant houses. 3) The ratios of residential mobility are affected by the characters of regions. Generally speaking, the ratios in urban area (Densely Inhabited District) are higher than the ratios in rural area. However, its characteristics vary in housing tenures. In the owned housing, mobility ratio is higher in urban areas, but in all rented housing, especially, public housing, mobility ratios are higher in rural areas than in urban areas. 4) The ratios of mobility are affected by the years of dwellings. In privately rented housing, the older the years of dwellings become, the lower its mobility ratios are. However, in the owned housing, the older the years of dwellings become, its mobility ratios rised slowly. 5) In our study, the ratios of mobility are caluculated as follows, that is, the figures are 3% in owned housing, 17% in all rented housing, 8% in public housing, 19% in privately rented housing, 18% in issued housing.
