Age Gap Between Spouses in South and Southeast Asia

Abstract

Age gap between spouses has important implications for a range of outcomes—from fertility and longevity, to gender relationships, marital quality, and stability. This paper examines the age gap between spouses in 12 countries in South and Southeast Asia. The average age difference (husband’s minus wife’s age) is positive in all countries and ranges from 2.7 in Myanmar to 8.4 in Bangladesh. Age homogamous marriages accounted for 5% of all marriages in Bangladesh to close to half of all marriages in Thailand. The proportion of age hypogamous marriages was uniformly low in all the countries except for Myanmar where it reaches close to 10%. Men’s marriage age has a stronger effect in determining the age gap. In general, the age gap for women with lower education was larger than for those with higher education. However, much of this effect was explained by the difference in marriage timing across educational groups.
