An alternative perspective on the Second Demographic Transition in East Asia
The Second Demographic Transition (SDT) has been a key theoretical framework for declining fertility and family changes, often marked by the decoupling of marriage and childbearing. While East Asia follows many SDT trends, its persistent link between marriage and childbearing has led to the view that East Asia is an exception. This study argues that the rise in intended premarital pregnancy within cohabitation in East Asia may reflect a trend fun…
Trends of the Delay and Variance of Childbirth Timing by Completed Number of Children
The timing of childbirth has undergone significant changes in the past decades. However, it may not be feasible for individuals with many children to further delay the timing of each childbirth given the biological constraints on fecundability and social age deadline for childbirth. Thus, the delay in having children and the increasing heterogeneity in its timing may present different trends when analyzed retrospectively by completed number of ch…
Is Intending to Have Children Rightist? A Research Note on Political Ideology and Fertility Intentions
Social scientists have long been interested in how attitudes and values influence fertility intentions and behaviors. The role of political ideology has, on the contrary, been overlooked. Right-wing people tend to be more religious, to hold more traditional views on gender roles and on the importance of the family. Therefore, right-wing people may be more likely to hold positive fertility intentions that individuals with other political orientati…
Lowest low fertility in Spain
BACKGROUNDSpain has one of the most enduring low levels of fertility in the world, but desired fertility there is still close to two children. OBJECTIVESWe document recent fertility trends and examine the reasons that women and men provide for not achieving their desired fertility. METHODWe use data from the 2018 Spanish Fertility Survey (14,556 women and 2,619 men).We provide a cohort and age perspective and compare women and men.We use retrospe…
Cross-sectional average length of life by parity
This study aims to present an alternative measure of fertility-cross-sectional average length of life by parity (CALP)-which: (1) is a period fertility indicator using all available cohort information; (2) captures the dynamics of parity transitions; and (3) links information on fertility quantum and timing together as part of a single phenomenon. Using data from the Human Fertility Database, we calculate CALP for 12 countries in the Global North…
An alternative version of the second demographic transition? Changing pathways to first marriage in Japan
BACKGROUND Growth in cohabiting unions and non-marital childbearing sits at the core of research on the second demographic transition and related discussions of family bifurcation and children’s diverging destinies. OBJECTIVE How should we think about these two highly influential and purportedly universal depictions of family change in low-fertility countries where the link between marriage and childbearing remains strong? Using data from large n…
The Decline of Spanish Fertility
The association between childlessness and voting turnout in 38 countries
This descriptive study aims to analyse the association between childlessness and voting turnout
The influence of social and economic ties to the spread of Covid-19 in Europe
Cross-Sectional Average Length of Life Childless
Increases in the average age at first birth and in the proportion of women remaining childless have extended the total number of years that women spend childless during their reproductive lifetime in several countries. To quantify the number of years that reproductive-age women live without children, we introduce the cross-sectional average length of life childless (CALC). This measure includes all the age-specific first-birth information availab…
Educational composition and parity contribution to completed cohort fertility change in low-fertility settings
Extensive literature has documented the contribution of rising women's education to decreases in completed cohort fertility (CCF). A key question related to the education-fertility relationship is to what extent the decrease in fertility is the result of changes in educational composition vs changes in fertility behaviours within educational categories. This study quantified the effect of educational expansion on fertility levels by decomposing t…
Order matters
Although nonmarital childbearing is uncommon in Japan, in contrast to the trends observed in other countries, the number of premarital pregnancies has increased. While prior studies have examined the determinants of premarital pregnancy, little is known ab
Expected years ever married
In the second half of the 20th century, remarkable marriage changes were seen: a great proportion of never married population, high average age at ï¬ rst marriage, and large variance in ï¬ rst marriage timing. Although it is theoretically possible to separate
