birthplace regions and regions of present residence. Although both Table III-4 (1) and (2) are based on the same values, (1) shows distribution of residential regional blocks by birth regional blocks (the sum of percentages in each horizontal row is 100), while (2) shows distribution of birth regional blocks by residential regional blocks (the sum of percentages in each vertical column is 100).

Looking at the percentage of respondents living in the same regional block as where they were born in Table III-4 (1) (listed along the diagonal from the upper left corner to the lower right corner of the table), it is found that the percentage is the highest among respondents born in the Chukyo (89.5%) and Tokyo (89.1%) blocks. On the other hand, the percentage is the lowest among those born in Tohoku (77.6%) and the Keihan blocks.
