Drawing on a uniquely large number of items on marital quality, this study explores the determinants of marital quality in Chitwan Valley, Nepal. Marital quality is measured with five dimensions identified through exploratory factor analysis, comprising satisfaction, communication, togetherness, problems, and disagreements. Gender, education, spouse choice, and marital duration emerge as the most important determinants of these dimensions of marital quality. Specifically, men, those with more schooling, those who participated in the choice of their spouse, and those who have been married longer have higher levels of marital quality. By contrast, caste, occupation, age at marriage, and number of children have little to no association with marital quality. However, while we identify key determinants of marital quality in this context, the majority of variation in marital quality remains unexplained.
