Most married couples do not share the same age. Across cultures and over time, age disparity has been observed in relationships between men and women (with men being the older party in the relationship). But how big is this gap in Singapore? To find out, we can dig into a dataset named Total Marriages by Marriage Order and Age Differential of Grooms To Brides, Annual on Data.gov.sg.

In the chart above, the horizontal axis represents the age differential of grooms to brides. Age differential is calculated by deducting the age of the bride from the age of the groom.

The first thing to be observed is that the distribution is asymmetric, skewing towards the right. Even though the mode of the distribution is 0, the numbers of negative observations tapers off faster than positive observations.

This agrees with our casual observation that it is uncommon to find couples where the groom is the younger party. It is also noteworthy that the distribution for remarriages is much flatter than first marriages.
