This paper analyzes the distribution of number of surplus rooms per household by time trend and tenure of dwelling, and the regional characteristics on the housing condition. The conclusions are as follows, 1. Larger the mean values of number of surplus rooms per household become, smaller Coefficient Variation values become. So, distribution with the larger mean value generates the sharper Normal Distribution around its mean value than the distribution with the smaller one. 2. Standard Deviation on the distribution of number of surplus rooms per household shows a tendency to have smaller values in the course of time, and each tenure may be assumed to have the same Standard Deviation value in the future. 3. On the regional level, mean values of number of surplus rooms per household vary to considerable ranges by prefectural unit. However, Standard Deviation values of each distribution are equivalent to each other among the regions on every time section. And, Standard Deviation values show a tendency to have smaller values in the course of time. This conclusions are applicable to any tenure of dwellings. 4. Resident's consiousness to the dwelling space is affected by both the absolute condition of dwelling space and the relative condition to the other in his living area. So, in spite of the increase of dwelling space, ratios of those who are unsatisfactory to their dwelling spaces are almost constant on every time section. 5. Differentials of the dwelling space per head among the regions show a tendency to be dimminishing. On the other hand, differentials of the dwelling space per head among the tenures of dwellings are expanding in the same regions.
