Abstract: In this section, we verify the reliability and consistency of the Comprehensive Survey of Living Conditions (CSLC), the National Survey of Family Income and Expenditure (NSFIE), and the Family Income and Expenditure Survey (FIES). To verify, we compare the employees f income in the three statistics with the salaries of the Basic Survey on Wage Structures (BSWS). The results demonstrate the following. First, there are no large differences in yearly income between that surveyed by CSLC and that surveyed by NSFIE, and also there are no large differences between those and income estimated by BSWS. Second, the age-yearly income profiles of three statistics in 1994 and 2009 are almost same. It can be concluded that yearly incomes surveyed in CSLC, NSFIE, and BSWS are consistent with each other. On the other hand, monthly total incomes of households whose household heads are employees filled into the Family Account Book (FAB) tend to be lower than monthly income estimated by yearly income filled into the yearly income schedule. There are differences in the employee fs income of household heads, employees f income of spouses and other household members, and in public pensions, etc. The possible reasons are as follows. First, some respondents forget to fill in bonuses or temporary incomes. Second, some respondents do not fill in any kind of regular income including monthly regular incomes. Third, missing incomes are seem to be classified as zero.
