Abstract
This paper deals with a distribution of house rent and household income in metropolitan areas. A summary of conclusion is as follows ; (1) In Keihin, Chukyo and Keihanshin metropolitan areas, the simultaneous distributions of house rent and household income, in the case of household living in private rental housing, can be well approximated by 2-dimentional logarithmic normal distribution. (2) An average of proportion of house rent to household income has been going down in the period from 1968 to 1978. Particularly, in the case of housing with joint use of facilities, that tendency is conspicuous. (3) A variance of proportion of house rent to household income increased in the period from 1968 to 1973, but it was stable from 1973 to 1978. (4) A correlation coefficients of the proportion of house rent to household income and household income itself are almost stable from 1968 to 1978. In the case of housing wth exclusive use of facilities, it is between -0.65 to -0.55, and in the case of housing with joint use of facilities, it is between -0.8 to -0.7. (5) Income elasticities of the proportion of house rent to household income have been converging to a certain extent. In the case of housing with exclusive use of facilities, it is between -0.7 to -0.6, in the case of housing with joint use of facilities, it is between -1.0 to -0.8. (6) Generally speaking, the characteristic of simultaneous distribution of proportion of house rent to household income and household income itself, changed substantially in the period from 1968 to 1973, but in the period of 1973 to 1978, it was almost stable.
