Coresidence of young adults with their parents in Japan: do sib size and birth order matter?
To identify the determinants of premarital and postnuptial coresidence among never-married young adults in Japan, multivariate logistic regressions were performed on data from the 1982 Single Youth Survey/National Fertility Survey. In Japan, it is traditional for young adults to live with their parents until marriage and some continue to coreside with their parents even after marriage, generally the eldest son. The results indicate that being female has a positive and significant effect on coresidence with parents of never-married young adults in Japan, while female gender has a significant negative effect on postnuptial coresidence plans. Age has a significant and positive effect on coresidence among men but a negative effect among women, while it has a positive effect on coresidence plans of young adults of both sexes. Eldest child status has a significant positive effect on coresidence and coresidence plans among males. Sib size has a significant negative effect among young adults of both sexes on coresidence. Overall, the results support the hypotheses that there is more pressure on daughters to stay home before marriage and to leave home after marriage, there is more pressure on eldest children to remain with their parents both before and after marriage, and crowding in large families increases the pressure on children to leave home before marriage. An unexpected finding was that self-employment on the part of the father has a significant negative effect on coresidence for both sexes, while self-employment among male youth has a positive effect on coresidence.
