The table gives information about the percentage of different types of households in Japan between 1980 and 2015.
Overall, the most noticeable changes were a steady increase in single-person households and a decline in both nuclear and extended families.
The share of single-person households grew steadily over the period, starting at 15% in 1980, rising to 22% in 1995, and reaching 29% in 2015. The category called 'other' also showed a gradual increase, going from 3% to 8% in the same years.
In contrast, nuclear families and extended families both dropped in proportion. Nuclear families made up the largest group at the beginning with 54%, but this fell steadily to 44% by 2015. Extended families showed a similar pattern, decreasing from 28% in 1980 to 19% in 2015.
