Nowdays, housing problems must be analyzed with consideration of the growth in household as well as the social class of household. The purpose of this study is to analyze household conditions with consideration to the growth in household. In this paper, we propose three indexes - "growth in household", "growth and number of household members" and "type of household with aged members". Using these indexes, we were able to clarify the changes in household and housing conditions according to the age of householders and the number of household members. For this paper, we used the special tabulation in Sapporo from 1988 Housing Survey of Japan.
