2. Population Aging in Different Municipalities

 

Differences in the degree of population aging between the municipalities of shi, machi or cho, and mura or son, delineated within a prefecture, are much more distinguishable than those in prefectures (Table 2). Among 3,233 municipalities, 1,729 municipalities, accounting for 53.5% of the total, indicated larger than 20.0%, 245 municipalities accounting for 10.5% showed larger than 30.0%. Above all, Towa-cho (machi), Yamaguchi prefecture presented the highest percentage of total population in the ages of 65 and over (47.4%) in 1995 (Table 3). Excluding for Towa-cho (machi), eight municipalities recorded larger than 40.0% in the percentage (Table 2). On the other hand, 123 municipalities, or only 3.8% of the total, indicated smaller than 10.0%. Among those municipalities, Urayasu-shi, Chiba prefecture adjacent to Tokyo metropolitan prefecture showed the smallest percentage (5.7%) (Table 3). Therefore, it is obvious that most of the municipalities experienced a remarkable extent of population aging in 1995. Distinct contrast in the age structures of populations between the eldest and the lowest municipalities (Towa-cho and Urayasu-shi) in the percentage in the elderly can be recognized in the Figures 5 and 6.
