In this paper, I presented the modified way to estimate the number of commuters between any two districts in a municipality, which I had developed in the previous paper, in order to improve accuracy of the estimated number of commuters. Then, I applied the modified way to the estimation of the number of commuters objected for 142 municipalities located on Chugoku area. By using the estimated numbers and other number of commuters to work in other municipalities and the number of workers working in their households, I analyzed the relation between two socioeconomic indexes and the percentage of the number of each kind of commuters or workers with regression analysis. I have also made six types of municipalities based on the percentages of the number of each kind of commuters or workers working in their households. As a result, I have gotten the following results.
1) The percentage of the number of workers working in their households, that of commuters working in the same district with their dwe ling one and that of commuters working in the central district of the same municipality would increase under the condition that the ageing of residents dwelling in the municipalities would proceed. 2) In the case of towns and villages near to their central cities, they highly rely on the job opportunities offered by the central cities, and the function offering job opportunities by the central district in them is low. There are many cases that these towns and villages don't rely on the job opportunities offered not only by the central district and other districts where commuters are not dwelling but also by the same district with their dwelling one. 3) The aging of residents and the reduction of the per capita income make the percentage of the number of commuters working in the districts excepting their dwelling or central district in the municipalities low, and the structure of commutation becomes simple.
