Marital fertility across the income distribution in South Korea
Tracking the decline of first marriage in South Korea
BACKGROUNDIn South Korea, where most births occur within marriage, the country's record-low fertility has put renewed attention on the long-term decline in first marriage.Despite rising policy and academic interest, systematic demographic analyses that disentangle structural and timing components of nuptiality change remain limited, especially in East Asia. OBJECTIVEThis study examines trends in the quantum and timing of first marriage in South K…
Drought and migration
Total number of births shrinking faster than fertility rates
South Korea’s total fertility rate reached 1.3 in 2001 and hit a record low (0.92) in 2019. The total number of births shrank even faster, recording a 45.9 per cent drop between 2001 and 2019. To understand the declining births and the contributing demographic factors, I decompose the change in the birth rate into mean generation size, fertility quantum, and tempo distortions, and evaluate their relative contributions to the decline. The remarkab…
The paradox of change
The scholarship on the association of religion and fertility has paid relatively little attention to East Asia, a region that has experienced rapid fertility declines. South Korea is an important setting to study this association as its fertility decreased
Migration, legality, and fertility regulation
Migrant-vs.-native differentials in reproductive behavior are typically examined through the prism of socioeconomic and cultural constraints that characterize the migration process and experiences. However, the literature seldom factors in migrant legal st
Ultra-low fertility in South Korea
The total fertility rate (TFR) in South Korea has fallen below 1.3 since 2001. The role of the rapid shift toward a late-childbearing pattern in driving Korean fertility decline to this ultra-low level has been little explored until now
Old Habits Die Hard? Lingering Son Preference in an Era of Normalizing Sex Ratios at Birth in South Korea
South Korea was among the first countries to report both an abnormally high sex ratio at birth (SRB) and its subsequent normalization. We examine the role of son preference in driving fertility intentions during a period of declining SRB and consider the contribution of individual characteristics and broader social context to explaining changes in intentions. We employ data from the National Survey on Fertility, Family Health and Welfare that spa…
Postponement and recuperation in cohort marriage
Despite continuing marriage delay in East Asia, little is known about the shift of marriage towards later ages and the concomitant decline in marriage
Understanding the Complexity of Ambivalence Toward Pregnancy
Ambivalence towards future pregnancy is common and may increase the risk of unprotected sex and unintended pregnancy. We propose that ambivalent attitudes toward pregnancy consist of subtypes that are differentially associated with contraceptive use. Using data from a nationally representative survey of unmarried young adults (N = 1,147), we constructed four categories of ambivalence based on attitudes toward a hypothetical pregnancy. Multivariat…
Educational differentials in cohort fertility during the fertility transition in South Korea
While there has been a considerable amount of research on the association between womenâ s education and fertility rates, few of these studies have examined the pattern of fertility differentials over the course of the fertility transition. As a country tha
