Family Norms and Declining First-Marriage Rates: The Role of Sibship Position in the Japanese Marriage Market.

This study explores how changes in sibship composition associated with fertility decline may, in conjunction with entrenched family norms and expectations associated with specific sibship positions, impact marriage rates and further reduce fertility. We evaluate this possibility by focusing on Japan, a society characterized by half a century of below-replacement fertility and widely shared family norms that associate eldest (male) children with specific family obligations. Harmonic mean models allow us to quantify the contribution of changes in both marriage market composition with respect to sibship position and sibship-specific pairing propensities to the observed decline in marriage rates between 1980 and 2010. One important finding is that marriage propensities are lower for those pairings involving men and women whose sibship position signals a higher potential of caregiving obligations, especially only-children. Another is that changes in marriage propensities, rather than changing sibship composition, explain most of the observed decline in marriage rates. We also found that marriage propensity changes mitigate the impact of the changing sibship composition to some extent. However, the limited contribution of changing sibship composition to the decline in first-marriage rates provides little support for a self-reinforcing fertility decline via the relationship between changing sibship composition and marriage behavior.

Marriage intentions, desires, and pathways to later and less marriage in Japan.

BACKGROUND: Understanding the trend toward later and less marriage is particularly important in low-fertility societies where alternatives to marriage are limited and childbearing outside of marriage remains rare. OBJECTIVE: Our goal in this paper is to advance our understanding of the wide variety of explanations offered for later and less marriage in Japan by focusing explicitly on marriage intentions and desires. METHODS: Using two sources of nationally representative data, we describe the prevalence of positive, negative, and passive marriage intentions and desires among men and women who have never been married. We also examine socioeconomic differences in intentions, patterns of marriage desires across young adulthood, and relationships between marriage desires and outcomes. By linking three pathways to later and less marriage (rejection of marriage, failure to realize marriage desires, and unplanned drifting into singlehood) to specific theoretical frameworks, we generate indirect insights into explanations for later and less marriage. CONCLUSIONS: Although the large majority of unmarried men and women want to marry, less than half of respondents married across nine waves of the Japanese Life Course Panel Survey. Among those who remained unmarried, roughly two-thirds can be classified as 'drifting' into singlehood, about 30% as 'failing to realize marriage desires,' and no more than 5% as 'rejecting marriage.' CONTRIBUTION: By extending the small body of research on marriage intentions and desires, this study provides a framework for thinking broadly about explanations for later and less marriage in Japan and highlights the importance of both failure to realize marriage desires and unplanned drifting into singlehood.
