The number of households is expected to decline in Tokyo and all prefectures from around 2045 to 2050. It is estimated the total number of households will drop by 5.6 percent from 2020's total to 52.61 million in 2050. Of those 52.61 million households, single-person homes will make up the largest share at 44.3 per cent. Couples with children will account for 21.5 per cent, and married couples without children will comprise 18.9 per cent. The number of 65-year-olds and up single-person households in this breakdown is expected to see a 46.9 per cent surge to 10.84 million in 2050. This increase will be particularly noticeable in urban areas with large concentrations of homes. In the Tokyo metropolitan area, this number is expected to rise at a pace nearing 70 per cent compared to 2020, significantly surpassing the national average of 46.9 per cent.
