Who “Fills in” for Siblings and How? A Multilevel Analysis of Personal Network Composition and Its Relationship to Sibling Size1

In the midst of widespread fertility decline, I examine the relationship between sibling number and support network composition using multilevel regression on data from 25 countries. A fundamental structural effect of having fewer siblings is that individuals have a smaller pool of available close‐kin alters with whom to construct support networks. Consequently, networks of people with fewer siblings should be composed of different sorts of relations. Results confirm that such compositional adjustment occurs in systematic ways. Compared to those with three or more siblings, adults with none to two siblings (as separate categories) are more likely to expect support from parents, extended kin, and close friends but not more likely to do so from spouses/partners and children. Single children are also more likely to include neighbors and have smaller‐sized and/or impersonal networks. These findings contradict the primacy of familial ties in social support networks. Moreover, adjustment of support networks towards nonsibling ties occurs in culturally expected ways. Those with fewer siblings are generally only more likely to turn to ties for the types of support typically associated with those relations—parents for instrumental and financial support and friends for emotional support. Single children, however, also violate institutionalized expectations of social support by turning to ties for a wider range of social support. The results suggest that continuing declines in fertility could bring about both reinforcement and rearticulation of the sociocultural framing of close personal relationships. Moreover, consistent with recent research, the results show that personal networks are influenced more by individual‐level than country‐level factors.     

Pathways of disadvantage: Explaining the relationship between maternal depression and children’s problem behaviors

A large body of literature documents that children of depressed mothers have impaired cognitive, behavioral, and health outcomes throughout the life course, though much less is known about the mechanisms linking maternal depression to children’s outcomes. In this paper, I use data from the Fragile Families and Child Wellbeing Study to estimate and explain the consequences of maternal depression for 5-year-old children’s internalizing and externalizing problem behaviors. Ordinary least squared (OLS) regression models and propensity score models show that children exposed to both chronic and intermittent maternal depression have more problem behaviors than their counterparts with never depressed mothers. Results also show that economic resources and maternal parenting behaviors mediate much of the association between maternal depression and children’s problem behaviors, but that relationships with romantic partners and social support do little to explain this association. This research extends past literature by illuminating some mechanisms through which maternal depression matters for children; by utilizing longitudinal measures of depression; by employing rigorous statistical techniques to lend confidence to the findings; and by using a large, diverse, and non-clinical sample of children most susceptible to maternal depression. Given that early childhood problem behaviors lay a crucial foundation for short- and long-term life trajectories, the social consequences of maternal depression may be far-reaching.     

The relationship between ethnicity and fertility in New Zealand

While there is a global shift towards smaller families, some groups maintain relatively high fertility rates. The 2013 New Zealand census data were used to investigate the nature of fertility between ethnicities in New Zealand. The NZ Deprivation Index 2013 was used as a measure of socioeconomic status to determine the relationships with fertility. The results mirror research outside of New Zealand in that socioeconomic status is inversely correlated to fertility. Using crude average fertility rates, sole-ethnicity Pasifika and Māori ethnic groups still have substantially higher fertility than sole-ethnicity Europeans and Asians ethnic groups, even when simultaneously accounting for age, socioeconomic status, education, and religious affiliation. Christians have more children than individuals reportedly without any religion, and fertility rates drop on average for mothers who have higher formal qualifications. Our findings suggest that cultural, or other ethnic-specific factors differentially affect fertility for Māori, Pasifika, New Zealand European, and Asians as aggregated ethnic categories, respectively.     

Sixty years of change in Tibetan fertility: An assessment

Existing knowledge of Tibetan historical population development is mostly based on ‘best-guess’ estimates and is heavily politicized. Using census data, I reconstruct the development of Tibetan fertility in China since the 1940s, with the objective of providing an independent assessment that can be used as benchmark for future studies and debates on Tibetan demography. Following major social and economic transformations starting in the 1950s, Tibetan fertility unexpectedly increased from the late 1950s to the late 1960s. As noted in several existing studies, Tibetan fertility in China then declined swiftly from the early 1980s onwards and has now reached values close to replacement level. Focusing on the 1950–70 period, I examine factors that contributed to shaping the Tibetan fertility increase in more detail. This confirms that changes in nuptiality and disease-related infertility both played a role in pushing up fertility rates among Tibetan women in China.     

Gender egalitarianism,perceived economic insecurity,and fertility intentions in Spain: A qualitative analysis

Economic uncertainty contributes to low fertility in many European countries. On the other hand, greater gender equality may positively influence fertility. This paper examines how these two forces interact in Spain. We use in-depth interviews to analyse fertility decision-making among young and highly educated partnered adults living in urban areas. Highly gender-egalitarian interviewees are less likely to perceive economic insecurity as an obstacle to proceeding to a next birth than less egalitarian interviewees. But there is not necessarily a difference in these two groups’ overall fertility intentions, as highly egalitarian interviewees’ greater valuation of stable employment for both partners requires institutional and policy support for dual-earner couples’ childrearing. When we look only at interviewees who express economic insecurity, somewhat higher fertility intentions are expressed by those holding less gender-egalitarian attitudes. Our results underline the complexity of the interrelationships between economic insecurity, gender egalitarianism, and fertility intentions.     

甘肃省居民生育意愿与生育目的的调查研究

文章利用2007年调查数据,分析研究了甘肃省居民的生育意愿和生育目的。调查发现．随着经济的发展和社会的进步,甘肃省居民的意愿生育数量不断减少,已经略低于更替生育水平,男孩偏好的意愿生育性别倾向仍然广泛存在,期望生育一儿一女是大部分甘肃居民最为普遍的愿望,意愿妇女初育年龄不断推迟．生育目的呈现出多元化趋势,但养老送终、传宗接代仍是目前最重要的生育目的。

Teen Childbearing and Depression: Do Pregnancy Attitudes Matter?

The relationship between teen childbearing and depression has been extensively studied; however, little is known about how young women's own attitudes toward becoming pregnant shape this association. This study used data from the National Longitudinal Study of Adolescent Health to investigate whether the relationship between teen childbearing and adult depression is moderated by adolescent attitudes toward becoming pregnant. The results showed that although, on average, women who had first births between ages 16 and 19 experienced no more depressive symptoms in adulthood than women who had first births at age 20 or older, the relationship between teen childbearing and adult depression varied significantly based on adolescent pregnancy attitudes. When they had negative adolescent attitudes toward getting pregnant, teen mothers had similar levels of depression as adult mothers, but when they had positive adolescent pregnancy attitudes, teen mothers actually had fewer depressive symptoms than women with adult first births.     

The demography of words: The global decline in non-numeric fertility preferences, 1993–2011

This paper examines the decline in non-numeric responses to questions about fertility preferences among women in the developing world. These types of response—such as ‘don’t know’ or ‘it’s up to God’—have often been interpreted through the lens of fertility transition theory as an indication that reproduction has not yet entered women’s ‘calculus of conscious choice’. However, this has yet to be investigated cross-nationally and over time. Using 19?years of data from 32 countries, we find that non-numeric fertility preferences decline most substantially in the early stages of a country’s fertility transition. Using country-specific and multilevel models, we explore the individual- and contextual-level characteristics associated with women’s likelihood of providing a non-numeric response to questions about their fertility preferences. Non-numeric fertility preferences are influenced by a host of social factors, with educational attainment and knowledge of contraception being the most robust and consistent predictors.     

Inequality and demographic response to short-term economic stress in North Orkney,Scotland, 1855–1910: Sector differences

We examine economic inequality and social differences in infant and child mortality, and fertility responses to food price changes in North Orkney, 1855–1910, using linked vital records. This small population featured a diverse occupational structure, limited land resources, and geographic isolation from mainland Scotland. Segments of Orkney’s non-agricultural working population were living so close to the margin of subsistence in normal years that an increase in food prices in bad years cost the lives of their children. Delayed childbearing, in addition to increased labour intensity, occupational diversification, and poor relief, failed to mitigate the negative effects of unfavourable prices in this group. While previous studies for Western Europe show a strong social gradient in mortality responses to food prices, and for Eastern Asia a strong household gradient, this study shows a strong sectoral gradient, indicating low standards of living for the non-agricultural working population well into the twentieth century.
