The Missing Brides Index from d'Albis and de la Croix

Why this new index ?

Gender imbalance in the young population is likely to have large social and economic consequences in South and East Asia. Among them, the marriage market could soon feature a large gap between the numbers of women and men, leaving a significant proportion of the latter without brides. In the article Missing Daughters, Missing Brides? , we propose a simple formula that gives, for some key demographic characteristics, the gender imbalance on the marriage market in a permanent regime.

Due to population growth and age difference between spouses, the gender imbalance at birth is not necessarily the same as the one at the age of marriage. Those characteristics along with the outcome of the marriage market are used to determine an endogenous growth rate of the population that is ultimately used to define our "Missing Brides Index".
