The book highlights a move away from the traditional paradigm of marriage as a social expectation towards a more individualized approach where personal aspirations and economic considerations hold significant sway. The authors explore how factors like increased female education and labor force participation, coupled with rising living costs, are reshaping attitudes towards marriage timing, cohabitation, and singlehood.

"Changing Marriage Patterns" underscores the growing diversity of partnership arrangements in Southeast Asia. While marriage remains the dominant norm, the book acknowledges the rising prevalence of cohabitation, delayed marriages, and transnational unions. It delves into the social and cultural factors underpinning these trends, including changing attitudes towards premarital sex, the influence of globalization, and the emergence of new relationship models.

The authors critically examine the social and economic implications of these evolving marriage patterns. They analyze the effects on family structures, fertility rates, and the well-being of children. The book also sheds light on the challenges faced by individuals navigating these changes, particularly in terms of social acceptance, legal rights, and economic security.
