Age differences at marriage and divorce.

This article explores the age difference of marrying and divorcing couples, calculated by subtracting the wife's age from the husband's. Age difference is of interest in the study of families and partnership behaviour. It is also important because of its link with broader socio-demographic changes, such as population ageing, delayed fertility and the provision of care. The main finding is that between 1963 and 2005, the distribution of age differences for all marriages is very similar in each year to the distribution of age differences for the subset of couples who married in that year, but have since divorced. While there is some evidence of small variations in the proportion of marriages that end in divorce by age difference, there does not seem to be evidence of a strong association.
