Ni Bhrolchain M. Age difference asymmetry and a two-sex perspective. European Journal of Population 1992; 8 (1): 23-45.

The paper shows that (a) the age difference between spouses can be and has been different for men and women: (b) male and female age differences can exhibit different trends; (c) the discrepancy is due to remarriage; (d) the age difference fluctuates substantially through time; (e) trends in the age difference are not readily interpretable as reflecting change in the relative status of the sexes: and (f) that trends in the age difference may be linked to marriage market conditions. The paper argues that marriage and fertility data for both men and women are increasingly necessary because of rises in marital breakdown and the associated divergence of the experience of men and women.
