【Aging, safety net and fiscal crisis in Japan】No.37: Number of households with heads aged over 65: by family type

According to the Household Projections for Japan 2015‐2040, as mentioned in Column No. 36, the number of one-person households will increase from 18.4 million in 2015 to 19.9 million in 2040, while the total number of households would decrease. This is because the number of one-person households with heads aged over 65 will increase rapidly. As shown in Table 1, one-person households with heads aged 65 to 74 will increase from 2.8 million in 2015 to 3.8 million in 2040. One-person households with heads aged over 75 are also expected to rise to 5.1 million in 2040 from 4.7 million in 2015.

A major problem with this is that these elderly one-person households will concentrate in large cities. As mentioned in Column No. 25, one in five of them is expected to suffer from dementia.
