This study examines the core concept of multiple egalitarianisms by integrating theories of gender equity and the gender revolution. Using the division of household labor and career development as analytical axes, it weaves together the four quadrants as an analytical framework. Drawing on in-depth interviews that explore the spouse-selection process and post-marital family life of hypogamous couples across generations, the study illustrates both the “de-gendering” of marriage assortative processes and the “doing gender” dynamics within family life. Specific cases are used to illustrate the multifaceted analytical framework of egalitarianism developed in this study. By incorporating the concepts of Gender-equity Theory / the First Gender Revolution, we can more comprehensively describe egalitarian practices in Taiwan’s hypogamous marriage pattern. Understanding how Taiwan may transition across the second, third, and fourth quadrants of egalitarianism is an important issue for future research.
