Using pooled cross-sectional data from recent censuses and wage surveys, ag
e-specific models of marriage prevalence are estimated in order to examine
whether rapid changes in the marital behavior of Japanese women reflect del
ayed marriage or an increase in the proportion who will never marry. Result
s indicate that higher wages for females, higher educational attainment, an
d recency of cohort are associated with lower marital prevalence at ages 30
-34, consistent with an interpretation of increasing nonmarriage. Given the
rapid pace with which Japan's population is projected to age, the rarity o
f nonmarital childbearing, and the relative absence of family alternatives
to marriage, art increase in the proportion of those who never marry would
have potentially major social, economic, and demographic consequences.
