Only children as adult women: Life course events and timing

A comparison between adult women who are only children and women who grew up with siblings is performed in relation to life course characteristics (events and timing), using a random sample of Canadian women (birth cohorts 1905–29 and 1930–44) surveyed, by telephone, in Vancouver and Victoria (total n of 1 251, with a response rate of approximately 60 percent). Initial analysis shows that female adult only children are less likely to have large families, more likely to marry and have their first child at older ages, more likely to attain high levels of education, and, among the younger cohort, more likely to cohabitate at younger ages. However, more refined analysis reveals that differences are, for the most part, the result of family of origin variables associated with sibsize rather than the result of only child status per se. Results are discussed in terms of their implications for research within the life course perspective, and in the light of possible changes accompanying population aging.
