There is reason to believe that the sharply rising age at marriage in Iran in recent years is in part caused by an age imbalance in the marriage market, which is itself a product of the baby boom of the early years of the 1979 Islamic Revolution. As a result of this baby boom, there were more than half a million more women than men in what social norms in Iran would consider marriage age. During 2000-2006 the shortage of men has intensified; the “marriage sex ratio”, which we define as the ratio of men 25-29 years old to women 20-24 years old, has decreased by about 25%, pushing up the age of marriage.
We use survey data from 1984-2007 to show how the average age gap has declined for cohorts of men and women born since the 1930s, from about 8 years to less than 3. The use of multiple surveys enables us to broaden the range of cohorts we study. We also estimate a model of the effect of the sex ratio on the age difference. We show that, controlling for individual characteristics, the sex ratio has the predicted effect on the average age gap. According to our estimates, higher sex ratios are associated with a lower age gap between spouses. These effects indicate that when there are fewer women of marriage age relative to men, the household is more balanced in terms of spouse ages, which generally favors the bargaining position of women in the household and bodes well for child education.
