Co-residence of household heads with parents in Japan: a multivariate explanation.

"This paper uses a multivariate logit model to study the factors affecting the Japanese household heads' propensities to co-reside with elderly parents, based on the micro data of a 1986 national survey. Our major findings are as follows. The most important factors are (1) inheritance of house or residential land from parent; (2) parent's spouseless status and age; (3) household head's sibling status; and (4) household head's nativity status. In a multivariate context, the negative effect of the household head's level of education was significant but not very important, whereas the presence of a working wife with child had a very weak positive effect on the co-residence with parent. Our overall conclusion is that the intergenerational co-residence in Japan is strongly affected by cultural norms and has a strong rational (economic) basis."
