Abstract
The long-term trend towards later and less marriage in the low-fertility countries of East and Southeast Asia has continued into the early years of the twenty-first century, and indeed accelerated in Japan, South Korea and Taiwan. This paper examines the extent to which this is a general trend cutting across all educational attainment groups, and the extent to which it can be explained by increasing proportions in the educational categories characterized by higher levels of singlehood (in the case of females, the higher levels of education). In the countries where the rise in singlehood has been the steepest, changing educational composition has played a relatively minor role in the case of women. For men, in all countries examined, it has played only a minor role, or actually worked against rising singlehood. The paper examines likely reasons for these trends.
