This paper provides an exploratory analysis of ethnocultural diversity and intergenerational support, examining factors that shape the attitudes of young adults toward sharing a home with an elderly parent. Data are drawn from a random sample of 565 young adults aged 19 to 35 living in the Greater Vancouver Regional District, whose primary ethnic identity is as members of one of three groups: British-, Chinese-, and Indo-Canadian. Utilizing a comparative, cross-cultural approach and logistic regression procedures, the study found the likelihood of young adults' expressing favourable attitudes to caregiving to be influenced by several factors associated with collectivistic systems of caregiving. Noteworthy is the finding that, after controlling for ethnocultural and socio-demographic factors, the best predictor of co-residence attitudes is the quality of a child's relationship with her/his mother. Findings are discussed with regard to their implications for intergenerational relations and support for aging families.
