among the respondents in the latter half of their 40s to the first half of their 50s; and (4) the percentage of respondents choosing “family-related reasons” decreased, while the percentage moving for “housing-related reasons” increased among the respondents in the latter half of their 70s to the first half of their 80s. It is also found that the percentage of respondents in the 15-19 age group moving “to attend school” increased significantly, from 33.3% to 41.3%. The percentage of migration due to “change in marital status” decreased from 31.3% to 26.3% among respondents in the latter half of their 20s and from 30.1% to 23.0% among respondents in the first half of their 30s. The percentage of migration for “work-related reasons” among respondents in their late 40s to their early 50s was 23 to 25% in the previous survey and this time it increased to 29 to 30%. Finally, the percentage of respondents who chose “family-related reasons” decreased while the percentage of “housing-related reasons” increased among respondents in the latter half of their 70s to the first half of their 80s. The results must be interpreted with caution since the sample sizes of these age groups become quite small.
