The purpose of this study is to clarify the characteristics of districts where the decrease rate of residential households are high and the timing when these rates increase. Therefore, we categorized the districts of Himeji City using statistic data available to the local government. Moreover, we predicted the timing when residential households decrease in each district. As a result of these analysis, the districts in Himeji city are classified into 12 types and the pattens of decreasing residential households are classified into 4 types. In addition, the rate of decreasing residential households in commercial districts and industrial districts tend to be different from the rate in residential districts. Furthermore, the rate of decreasing residential households tend to be relatively slow in districts where vacant houses are likely to be redistributed into the market.
