The purpose of this study is according to the previous paper. In this report the content of our research is divided roughly into three. The first one is the analysis on the correlation between income and expenditure of the two households. The second one is the calculation of the score on the income elasticity. The third one is the analysis on the consumption structures of the two as follows: Referring to ten major expenditures, we applied the factor analysis and the cluster analysis.The results are shown below : (1) Regardless of households, the income of households head has significant plus correlation to the current expenditure and the disbursements other than the expenditure. While the income has significant minus correlation to Food expenditure in one-income households, it has no correlation in another households. (2) The income of wife has almost the same correlation to expenditures with that of households head. (3) When we classify ten major expenditures into necessary expenditures, luxurious ones, and lower ones by the score on the income elasticity, we meet with different results among two households as regards five expenditures. (4) In each household, we find a few factors on ten major expenditures: In one-income house-holds, the first principal component can be regarded as a life development factor, the second as a life completion factor, the third as a fixed expenditure factor. In dual-income households, the first one can be regarded as the factor on life development and completion, the second as a fixed expenditure factor. (5) Ten major expenditures of the two households are cluster-analyzed as follows: In one-income households, they are divided into three; Food expenditure, Cloth and footwear expenditure, and the expenditures on life development and completion. In another households, they are also divided into three; the expenditures on life development and completion, fixed expenditures, and occasional expenditures.
