4.2.1 Data overview

The utilized data and the utilization method of the data in the present study are shown in Table 1.

### 4.2.2 Distribution map of aging population and nursing facilities

The distribution of the aging population and nursing facilities are, respectively, shown in Figures 5 and 6. As shown in Figure 5, the southeastern part has a high aging population, and there are old housing complexes in this area. In Figure 6, the admission type of nursing facilities is only shown as mentioned in Section 3.2.1, indicating that they are distributed throughout the entire Chofu City excluding the central area.

Figure 7 is the evaluation results when using the specialization coefficient of the population aging rate. Areas with particularly high evaluation points are outlined by bold black lines. As evident in Figure 7, in addition to the areas with a high aging population mentioned in Section 4.2.2, evaluation points were also high in the eastern areas. On the other hand, evaluation points in the northern part of Chofu

Figure 5. Distribution of the aging population.

Chofu City was selected as the evaluation target area, as the aging population (age 65 or over) has already exceeded the youth population (under age 15), and the aging population is expected to increase in the future. According to the survey on the aging population in Chofu City [31], 23,545 people, equivalent to approximately 10% of the total population, fit in the current age range of the present study subject which is 75 and over. In the present study, evaluation will be conducted in the unit
