The quantity-Quality trade-Off of children In a developing country: Identification using chinese twins

Testing the trade-off between child quantity and quality within a family is complicated by the endogeneity of family size. Using data from the Chinese Population Census, we examine the effect of family size on child educational attainment in China. We find a negative correlation between family size and child outcome, even after we control for the birth order effect. We then instrument family size by the exogenous variation that is induced by a twin birth and find a negative effect offamily size on children's education. We also find that the effect of family size is more evident in rural China, where the public education system is poor. Given that our estimates of the effect of having twins on nontwins at least provide the lower bound of the true effect of family size, these findings suggest a quantity-quality trade-off for children in developing countries.     

Birth order matters: the effect of family size and birth order on educational attainment

Using the British Household Panel Survey, we investigate if family size and birth order affect children’s subsequent educational attainment. Theory suggests a trade-off between child quantity and “quality” and that siblings are unlikely to receive equal shares of parental resources devoted to children’s education. We construct a new birth order index that effectively purges family size from birth order and use this to test if siblings are assigned equal shares in the family’s educational resources. We find that the shares are decreasing with birth order. Ceteris paribus, children from larger families have less education, and the family size effect does not vanish when we control for birth order. These findings are robust to numerous specification checks.

Prenatal Health,Educational Attainment,and Intergenerational Inequality: The Northern Finland Birth Cohort 1966 Study

In this article, we study the effects of prenatal health on educational attainment and on the reproduction of family background inequalities in education. Using Finnish birth cohort data, we analyze several maternal and fetal health variables, many of which have not been featured in the literature on long-term socioeconomic effects of health despite the effects of these variables on birth and short-term health outcomes. We find strong negative effects of mother’s prenatal smoking on educational attainment, which are stronger if the mother smoked heavily but are not significant if she quit during the first trimester. Anemia during pregnancy is also associated with lower levels of attained education. Other indicators of prenatal health (pre-pregnancy obesity, mother’s antenatal depressed mood, hypertension and preeclampsia, early prenatal care visits, premature birth, and small size for gestational age) do not predict educational attainment. Our measures explain little of the educational inequalities by parents’ class or education. However, smoking explains 12%—and all health variables together, 19%—of the lower educational attainment of children born to unmarried mothers. Our findings point to the usefulness of proximate health measures in addition to general ones. They also point to the potentially important role played by early health in intergenerational processes.     

Family size and children’s education in Thailand: Evidence from a national sample

Analysis of a large, nationally representative survey shows that family size exerts a substantial negative influence on the probability that a child will attend secondary school in Thailand. The primary mechanism underlying this effect is most likely the dilution of familial resources available per child associated with larger numbers of children. The extent and the level of schooling at which this effect operates vary with the household level of wealth and with rural or urban residence. Because fertility decline is leading to a major increase in the proportion of children who come from small families, falling birth rates contribute to increasing educational attainment in Thailand.     

Sibship size and educational attainment. A joint test of the Confluence Model and the Resource Dilution Hypothesis

Studies on family background often explain the negative effect of sibship size on educational attainment by one of two theories: the Confluence Model (CM) or the Resource Dilution Hypothesis (RDH). However, as both theories - for substantively different reasons - predict that sibship size should have a negative effect on educational attainment most studies cannot distinguish empirically between the CM and the RDH. In this paper, I use the different theoretical predictions in the CM and RDH on the role of cognitive ability as a partial or complete mediator of the effect of sibship size to distinguish the two theories and to identify a unique RDH effect on educational attainment. Using sibling data from the Wisconsin Longitudinal Study (WLS) and a random effect Instrumental Variable model I find that, in addition to a negative effect on cognitive ability, sibship size also has a strong negative effect on educational attainment which is uniquely explained by the RDH.     

Knowledge and Use of Birth Control in Barbados

Based on material collected in Barbados in 1964, this paper examines knowledge and use of birth control in terms of three types of family union-married, common law, and visiting. Analysis of knowledge of birth control is dealt with for the sample at large, for educational attainment, and for the average number of methods known by each woman. The relative importance of the different methods known is also treated by family type and education.The extent to which women in the sample make use of birth control is discussed from four aspects. First, the growing use of the different methods among younger-age cohorts is made evident from tabulations of methods-last-used. Second, information on the agencies and individuals recommending the use of different contraceptives emphasizes the degree to which the partner's influence is responsible for resort to birth control. Third, the proportions of users in religious groups show that religion is not a barrier to the use of any method. Fourth, the material is treated from the standpoint of age cohorts, since there is, in many cases, a vagueness as to the age at which use began, although women are able to identify the inter-pregnancy period when use began.     

Do Measured and Unmeasured Family Factors Bias the Association Between Education and Self-Assessed Health?

The association between educational attainment and self-assessed health is well established but the mechanisms that explain this association are not fully understood yet. It is likely that part of the association is spurious because (genetic and non-genetic) characteristics of a person’s family of origin simultaneously affect one’s educational attainment and one’s adult health. In order to obtain an unbiased estimate of the association between education and health, we have to control for all relevant family factors. In practice, however, it is impossible to measure all relevant family factors. Sibling models are particularly appropriate in this case, because they control for the total impact of family factors, even if not all relevant aspects can be measured. I use data on siblings from a US study (MIDUS) and Dutch study (NKPS) to assess the total family impact on self-assessed health and, more importantly, to assess whether there is a family bias in the association between educational attainment and self-assessed health. The results suggest that there is a substantial family effect; about 20% of the variation in self-assessed health between siblings can be ascribed to (measured and unmeasured) family factors. Measured family factors, such as parental education and father’s occupation, could account only for a small part of the family effect. Furthermore, the results imply that it is unlikely that there is substantial bias due to family effects in the association between education and self-assessed health. This strengthens the conclusions from prior studies on the association between education and self-assessed health.     

Is the Association Between Education and Fertility Postponement Causal? The Role of Family Background Factors

A large body of literature has demonstrated a positive relationship between education and age at first birth. However, this relationship may be partly spurious because of family background factors that cannot be controlled for in most research designs. We investigate the extent to which education is causally related to later age at first birth in a large sample of female twins from the United Kingdom (N = 2,752). We present novel estimates using within–identical twin and biometric models. Our findings show that one year of additional schooling is associated with about one-half year later age at first birth in ordinary least squares (OLS) models. This estimate reduced to only a 1.5-month later age at first birth for the within–identical twin model controlling for all shared family background factors (genetic and family environmental). Biometric analyses reveal that it is mainly influences of the family environment—not genetic factors—that cause spurious associations between education and age at first birth. Last, using data from the Office for National Statistics, we demonstrate that only 1.9 months of the 2.74 years of fertility postponement for birth cohorts 1944–1967 could be attributed to educational expansion based on these estimates. We conclude that the rise in educational attainment alone cannot explain differences in fertility timing between cohorts.     

Two Decades of Negative Educational Selectivity of Mexican Migrants to the United States

Immigration is commonly considered to be selective of more educated individuals. Previous US studies comparing the educational attainment of Mexican immigrants in the United States to that of the Mexican resident population support this characterization. Upward educational‐attainment biases in both coverage and measurement, however, may be substantial in US data sources. Moreover, differences in educational attainment by place size are very large within Mexico, and US data sources provide no information on immigrants' places of origin within Mexico. To address these problems, we use multiple sources of nationally representative Mexican survey data to re‐evaluate the educational selectivity of working‐age Mexican migrants to the United States over the 1990s and 2000s. We document disproportionately rural and small‐urban‐area origins of Mexican migrants and a steep positive gradient of educational attainment by place size. We show that together these conditions induced strongly negative educational selection of Mexican migrants throughout the 1990s and 2000s. We interpret this finding as consistent with low returns to education among unauthorized migrants and few opportunities for authorized migration.     

Employment and the Use of Birth Control by Sexually Active Single Hispanic,Black, and White Women

Previous studies of the use of birth control by sexually active single women tend to emphasize family background and aspirations, and restrict their attention to teenagers. We elaborate this framework by considering how labor market experiences might shape the birth control practices of women in their late teens and twenties. Data from the National Longitudinal Survey of Labor Force Experiences — Youth Cohort provide evidence that employment histories and wages influence birth control practices, net of the effects of family background, aspirations, and educational attainment. Several pronounced racial and ethnic differences are found.     

Growing Wealth Gaps in Education

Prior research on trends in educational inequality has focused chiefly on changing gaps in educational attainment by family income or parental occupation. In contrast, this contribution provides the first assessment of trends in educational attainment by family wealth and suggests that we should be at least as concerned about growing wealth gaps in education. Despite overall growth in educational attainment and some signs of decreasing wealth gaps in high school attainment and college access, I find a large and rapidly increasing wealth gap in college attainment between cohorts born in the 1970s and 1980s, respectively. This growing wealth gap in higher educational attainment co-occurred with a rise in inequality in children’s wealth backgrounds, although the analyses also suggest that the latter does not fully account for the former. Nevertheless, the results reported here raise concerns about the distribution of educational opportunity among today’s children who grow up in a context of particularly extreme wealth inequality.     

What is Most Important: Social Factors, Health Selection, and Adolescent Educational Achievement

This paper explores the relative importance of social factors and health measures in predicting educational achievement in early and late adolescence using population-based administrative data. The sample was made up of 41,943 children born in Manitoba, Canada between 1982 and 1989 and remaining in the province until age 18. Multilevel modeling nests each individual (level 1) within a family (level 2) residing within a neighborhood (level 3). Most important in predicting adolescent achievement were a broad socioeconomic status index (and a narrower measure of household income), being on social assistance, mother’s age at first birth, gender, residential mobility, the presence of ADHD/Conduct disorders, and measures of family functioning (child taken into care or offered protection services and family structure history). Family size, birth order, and newborn characteristics (birthweight, APGAR, gestational age) were statistically significant but of little importance in explaining the outcomes. Both examining regression coefficients and systematically omitting variables showed social factors (often emphasized by epidemiologists) to have markedly greater effects than the combination of health measures (often stressed by economists) in predicting achievement. However, mental health in childhood is identified as among the important predictors. Record linkage across population datasets from health, education, and family services ministries allowed: tracking health and educational attainment at different times in a child’s life, following a large number of cases across childhood, considerable sensitivity testing, controlling for unmeasured family and neighborhood effects, generating an extensive list of predictors, estimating effect sizes, and comparing Manitoba results with those of well-known American studies.     

Gendering fertility: Second births in Sweden and Hungary

With the growing prevalence of the dual-earner family model in industrialized countries the gendered nature of the relationship between employment and parenting has become a key issue for childbearing decisions and behavior. In such a context taking into account the societal gender structure (public policies, family-level gender relations) explicitly can enhance our understanding of contemporary fertility trends. In this paper we study the second birth, given its increasing importance in the developed world as large proportions of women remain childless or bear only one child. We focus on Sweden where gender equality is pronounced at both the societal and the family level and on Hungary where the dual-earner model has been accompanied by traditional gender relations in the home sphere. Our analysis is based on data extracted from the Swedish and Hungarian Fertility and Family Surveys of 1992/93. We use the method of hazard regression. The results suggest that the second-birth intensity increases as the combination of parenthood and labor-force attachment of either parent is facilitated. We see this in the effect of family policies in Sweden and in the higher second-birth intensity of couples who share family responsibilities as compared to those with traditional gender-role behavior in both countries. Also, the lack of any visible impact of men's educational attainment in both Sweden and Hungary is probably linked to public policies as state support for families with children has reduced the importance of income for second childbearing. A positive educational gradient for Swedish women and an essentially zero gradient in Hungary reflects the success of policy measures in reducing fertility cost for more educated women in both countries.     

Family dissolution, family reconstitution, and children’s educational careers: Recent evidence for Sweden

Both longitudinal and cross-sectional analyses on a large and recent Swedish data set demonstrate that, compared to children in intact families, children who have experienced family dissolution or reconstitution show lower educational attainment at age 16. Time constraints do not seem to be an important mechanism behind the negative effect of separation. Economic deprivation affects children s attainment negatively, but downward social mobility appears to be an even more important causal mechanism: Losing the parent with the higher social position probably reduces social capital and aspirations. When we control for socioeconomic characteristics, a small net effect of separation and reconstitution remains.     

A study in miniature of Chinese population

The author analyses the demographic situation of a rural township in West China. He begins by discussing the geographical setting and historical background of the township, pointing out that the bulk of the population is made up of descendants of Hakka immigrants.

In the analysis of the age and sex distribution, special attention is paid to the cultural factors which may affect the reported unequal sex ratio for various age-groups.

In the subsequent discussion, the population of families is classified according to type and size of landholdings and also according to structural family type. The thesis that family size increases with size landholdings is supported by the data for this township and the author presents hypotheses to account for the correlation between large landholdings and large family size. The percentage distribution according to highest educational attainment of the population over six years of age is presented, as well as data which indicate that literacy and educational attainment is lowest for landless workers, increases for landholders with increase in size of holdings, and is highest for merchants and professionals.

The data on which this paper is based were gathered by the author in 1949-50. Population figures collected by local administrators for a 1947 report were reworked and revised through direct investigation and additional material was gathered in detail for the entire population of one representative sub-division of the township; and a random sample of the family heads of that sub-division was singled out for special investigation by means of a structured interview. Such studies in miniature, it is felt, can only suggest hypotheses of wider application; in sufficient number, however, they might provide useful data for China and other countries where modern censuses are still impracticable.     

Educational attainment of children from single-parent families: Differences by exposure,gender, and race

This article examines the effect of living in a single-parent family on educational attainment by gender and race. According to household production theory, the reduction in parental resources for human capital investment in children living in a single-parent family should lower their educational attainment. Using matched mother-daughter and mother-son samples from the National Longitudinal Surveys, we constructed precise measures of the age and length of time a child lived in a single-parent family. Empirical findings show that the negative effect of living in a single-parent family (1) increases with the number of years spent in this type of family, (2) is greatest during the preschool years, and (3) is larger for boys than girls.     

Sharing the wealth: The effect of siblings on adults’ wealth ownership

Inequality in wealth has been well-documented, but its causes remain uncertain. Family processes in childhood are likely to shape adults' wealth accumulation, but these factors have attracted little attention. I argue that family size matters: children from larger families accumulate less wealth than do those from smaller families. Siblings dilute parents' finite financial resources and nonmaterial resources, such as time. This diminishment of resources reduces educational attainment, inter vivos transfers, and inheritance. Reduced educational attainment and transfers alter financial behavior; saving; and, ultimately, adults' wealth. I demonstrate that sibship size is associated with lower overall wealth in adulthood and that parents' resources and education, respondent's education, financial transfers, and financial behavior all mitigate the effect of siblings. Sibship size also reduces the likelihood of receiving a trust account or an inheritance and decreases home- and stock ownership. The findings provide important insights into early family processes that shape wealth accumulation and inequality.     

Educational stratification among Arabs and Jews in Israel: historical disadvantage, discrimination, and opportunity

Arabs in Israel are a heterogeneous but largely underprivileged minority with a history of disadvantage in several domains, including education and employment. In this paper, we document changes in their attainment of various educational levels across cohorts born from the mid-1920s to the 1970s. We make comparisons among different Arab religious groups, between men and women, and between Arabs and the majority Jewish populations in Israel. We find that over consecutive birth cohorts, substantial ethnic differences in educational attainment have narrowed at the lower levels of schooling, but have increased at higher levels. Moreover, the results indicate that the disadvantage of Muslim Arabs in terms of entry into and completion of high school can be accounted for only partially by differences in the social status of their parents and characteristics of their neighbourhoods. The findings suggest that long-term historical differences among groups and discriminatory practices towards Arabs are important factors in explanations of disparities in educational attainment.     

Diverging fertility among U.S. women who delay childbearing past age 30

In this paper I examine the evolving association between educational attainment and the timing of births. In the late 1970s, women with four-year college degrees had lower first birth rates before age 30 than women with less education, but rates of first births were similar for the two groups after age 30. From the 1970s to the 1990s, first birth rates decreased before age 30 for all women, but increased after age 30 only for women with four-year college degrees. Parity 2 birth rates also increased for college graduates with a first birth after age 30. These results document widening educational differences in fertility timing between 1975 and 1995, which may reflect period changes at later ages in women's work and family lives.     

Family size and children’s education in Vietnam

Data from the nationally representative 1994 Inter-Censal Demographic Survey are used to examine the association between family size and children s schooling in Vietnam. The data provide information on several education measures for all children over age 10, including children no longer residing in the household. Although a clear inverse bivariate association between family size and children s school attendance and educational attainment is evident, multivariate analysis controlling for urban/rural residence, region, parents’ education, household wealth, and child’s age, reveals that much of this association, especially that predicting educational attainment, is attributable to these other influences. Moreover, much of the effect that remains after statistical adjustment for the other influences is seen mainly at the largest family sizes. We consider the implications of these findings for current population policy in Vietnam and the possible features of the Vietnamese context that might account for the modest association.
