Age‐Heterogamy and Canadian Unions

Abstract This study provides a much‐needed exploration of the determinants of age‐discrepant unions in Canada. What little research has been conducted in this area of sociology of the family is now outdated. Further, the growing number of Canadians living in nonmarital cohabitation warrants their inclusion in any consideration of contemporary, heterosexual unions, and we have done so here. Utilizing multinomial Iogit modeling techniques, we analyze data drawn from the 1995 Canadian General Social Survey. We find that cohabitations and remarriages are more likely to be age‐discrepant than marriages, and that as age at union formation increases, so does the likelihood that the union will be age‐heterogamous. Although we hypothesized a positive relationship between education and the chances of age‐heterogamous unions because the availability of eligible mates may decrease with education, we actually find an inverse association for women: a one‐level increase in education decreases a woman's odds of entering an age‐discrepant union by about 4 percent. We speculate that for women, greater education (economic position) may increase age‐homogamy because they may be more economically attractive and thus more able to select a partner of their own age.
