Abstract
On this paper, firstly we analyzed the the tendency of the elderly household ratio in public housing estates in Osaka prefecture, based on the management data of 364 public housing estates (about 123000 households) in December 1994. Secondly, defining householder with the age 65 through 74 as the younger elderly household and those with the age 75 and more as the older elderly household, we tried to predict the elderly household numbers and ratio every 5 years from 1995 to 2010. Through this prediction, we made it clear that the aging process in Osaka public housing estates and the older elderly household would show evident increase in 15 years, especially in the public housing estates constructed before 1965, which are low-rented, small in size and in good location.
