Table 1 shows the profile of an average working household employed by companies, healthcare institutions, and government agencies. Both gross and disposable monthly income has been decreasing. Therefore, it is understandable why Japan's economic growth has remained subdued. As consumers' propensity to spend has declined, it is not surprising that workers are cautious about consumption.
Table 2 shows the profile of an average non-working household (including retirees). Non-working households' monthly consumption expenditures are 75% of employed households' expenditures (as of 2016). The decrease in consumption expenditures between 2013 and 2016 is smaller for non-working than for working households. This suggests that the living of retirees has remained stable.
