Selective gender differences in childhood nutrition and immunization in rural India: The role of siblings

This article examines the role of the sex composition of surviving older siblings on gender differences in childhood nutrition and immunization, using data from the National Family Health Survey, India (1992-1993). Logit and ordered logit models were used for severe stunting and immunization, respectively. The results show selective neglect of children with certain sex and birth-order combinations that operate differentially for girls and boys. Both girls and boys who were born after multiple same-sex siblings experience poor outcomes, suggesting that parents want some balance in sex composition. However, the preference for sons persists, and boys who were born after multiple daughters have the best possible outcomes.     

Explaining Asia's “Missing Women”: A New Look at the Data

The fact that millions of females are “missing” in East Asia and South Asia has been attributed to cultural factors that support strong son preference in these countries. A widely disseminated paper by Emily Oster argues that a large part of this phenomenon can be attributed to excessively masculine sex ratios at birth resulting from maternal infection with hepatitis B. If her thesis is true, current policies to address this problem would need to be reframed to include biological factors in addition to cultural factors. The data show, however, that whether or not females “go missing” is determined by the existing sex composition of the family into which they are conceived. Girls with no older sisters have similar chances of survival as boys. However, girls conceived in families that already have a daughter experience steeply higher probabilities of being aborted or of dying in early childhood. This indicates that cultural factors still provide the overwhelming explanation for the “missing” females.     

Shortage of girls in China today

China has the most severe shortage of girls compared to boys of any country in the world today, as documented by China's surveys and censuses up to 2000. This article evaluates data on sex ratios in China since before the founding of the People's Republic, and shows that the relative dearth of girls has become more extreme during the last two decades, and that the problem is real and not merely due to undercounting of girls. Daughters are lost primarily through sex-selective abortion, secondly through excess female infant mortality, and thirdly through neglect or mistreatment of girls up to age three, in cities as well as rural areas. Until recently, the dearth of girls was confined to second or higher-order births, but now couples in some provinces are using sex-selective abortions for first births. Maps show the geographical concentration of life-threatening discrimination against girls and its spread over time. Son preference, low fertility and technology combine to cause the loss of daughters in China today and compulsory family planning and the one-child policy exacerbate the problem. The discussion includes what the People's Republic of China has done to ameliorate life-threatening discrimination against girls and what further steps might be taken to improve the situation.     

High Fertility and Children's Schooling in Ghana: Sex Differences in Parental Contributions and Educational Outcomes

This paper explores the linkages at the family level between sustained high fertility and children's schooling in Ghana, in the context of a constrained economic environment and rising school fees. The unique feature of the paper is its exploration of the operational significance of alternative definitions of “sib size” – the number of “same-mother” siblings and “same-father” siblings – in relation to enrolment, grade attainment, and school drop-out for boys and girls of primary and secondary school age. The analysis is based on the first wave of the Ghana Living Standards Measurement Survey (GLSS) data, collected in 1987–88. The results of the statistical analysis lead to the conclusion that the co-existence of high fertility, rising school costs, and economic reversals is having a negative impact on the education of girls, in terms of drop-out rates and grade attainment. Some of the costs of high fertility are borne by older siblings (particularly girls) rather than by parents, with the result that children from larger families experience greater inequality between themselves and their siblings by sex and birth order. Because fathers have more children on average than mothers, the inequality between their children appears to be even greater than between mothers' children, particularly given the importance of fathers' role in the payment of school fees. The paper concludes that the greatest cost for children in Ghana of sustained high fertility is likely to be the reinforcement of traditional sex roles, largely a product of high fertility in the past.     

A formal theory for male-preferring stopping rules of childbearing: sex differences in birth order and in the number of siblings

Through mathematical deductions, this article shows certain macro-demographic consequences of individually employed male-preferring stopping rules in childbearing. It is shown that male-preferring stopping rules generate differences between boys and girls in birth order and in the number of siblings. Two situations are considered regarding the latent probability of having a boy: population homogeneity and population heterogeneity. The sex difference in the number of siblings exists even under population homogeneity, and the difference remains constant when each couple employs a distinct alternative rule. On the other hand, the sex difference in the birth order exists only under population heterogeneity. Substantive implications of these findings are discussed.     

Center-Based Care in the Context of One-Child Policy in China: Do Child Gender and Siblings Matter?

We examined the effects of child gender and siblings on center-based care enrollment in the context of China’s one-child policy and its tradition of preference to have many children, especially sons. Using data from the China Health and Nutrition Survey (CHNS) 2000 wave and multilevel logistic regression models, we found that children without siblings consistently had higher odds of receiving center-based care than those with siblings, while there was no evidence that child gender mattered. Further analyses did not show evidence that the effects of child gender and siblings were moderated by household and community resources or local one-child policy. However, we did find that the presence of male, older, or school-age siblings (as compared to female, younger, or preschool-age siblings) reduced preschoolers’ odds of receiving center-based care. This was possibly because parents valued formal education much more than preschools and thus focused more on boys when they entered elementary schools than on their sisters or younger brothers. These findings suggest that more attention needs to be given to the equal education opportunities for boys and girls as well as for children with and without siblings.     

Does son preference influence children's growth in height? A comparative study of Chinese and Filipino children

Research has demonstrated that son preference has a serious impact on the survival and well-being of female infants and children in some parts of South and East Asia, but little is known about the consequences of son preference in later childhood and adolescence. We compare children's growth trajectories in height over childhood and adolescence in China, where the level of son preference is relatively high, and the Philippines, where it is relatively low. Children's height reflects long-term nutritional status and exposure to infectious diseases, both influenced by household decision-making and, presumably, by a preference for sons. Using data from two high-quality longitudinal studies and multilevel growth models, we find that male children in China show an additional height advantage relative to their female counterparts, when compared to the sex difference in growth trajectories in the Philippines. Further analysis reveals that the additional advantage of males in China is stronger in rural areas.     

Girl adoption in China—A less-known side of son preference

In 1987, 4 per cent of girls were adopted within China. Why? Unlike infanticide, abandonment rids parents of daughters while preserving the supply of potential brides. In fact, an erstwhile tradition common in Fujian and Jiangxi provinces had parents of sons adopting an infant girl to serve as a future daughter-in-law and household help. Analysing a nationally representative 1992 survey of children, we found that: (1) girl adoptions were concentrated in the above-mentioned provinces; (2) girls were predominantly adopted by families with sons; (3) adopted girls faced substantial disadvantage as measured by school attendance at ages 8–13. In the 1990s, as the sex ratio at birth climbed, were girls aborted rather than abandoned? Observing that in the 2000 census too many girls appear in families with older sons, we estimated that at least 1/25 girls were abandoned in the 1990s, a proportion that in Fujian and Jiangxi may have peaked at 1/10 in 1994.

Siblings, child labor, and schooling in Nicaragua and Guatemala

This paper explores empirically within-household gender and sibling differences in child labor, domestic work, and schooling of Guatemalan and Nicaraguan children. The main results show that older boys spend more time engaged in market and domestic work, whereas older girls spend more time in domestic work than their younger siblings. These results are independent of whether the younger sibling is a boy or a girl, which suggests that there is no substitution within the household of younger for older siblings in market and domestic work. This paper’s findings show the relevance of domestic work and gender differentials in children’s allocation of time in developing countries.     

Demography and Social Science

Research has demonstrated that son preference has a serious impact on the survival and well-being of female infants and children in some parts of South and East Asia, but little is known about the consequences of son preference in later childhood and adolescence. We compare children's growth trajectories in height over childhood and adolescence in China, where the level of son preference is relatively high, and the Philippines, where it is relatively low. Children's height reflects long-term nutritional status and exposure to infectious diseases, both influenced by household decision-making and, presumably, by a preference for sons. Using data from two high-quality longitudinal studies and multilevel growth models, we find that male children in China show an additional height advantage relative to their female counterparts, when compared to the sex difference in growth trajectories in the Philippines. Further analysis reveals that the additional advantage of males in China is stronger in rural areas.     

Parental Resources, Schooling Achievements, and Gender Schooling Gaps: Evidence of Change over 25 years in Rural Guatemala

We use village census data and linear regression models to examine changes between 1975 and 2002 in the associations of parental resources with boys’ and girls’ schooling in four rural Guatemalan villages. Levels of schooling in 1975 were universally low for children 7–17 years. Large increases in schooling achievements occurred between 1975 and 2002. By 2002, schooling levels were comparable for younger boys and girls (7–12 years, N = 3,525) and favored older boys compared to older girls (13–17 years, N = 2,440) by about 0.5 grades. The associations of household standard of living and maternal schooling with schooling among girls diminished over time and became more comparable with these associations among boys, and the associations of household standard of living with schooling among older boys declined and became more comparable with these associations among girls. Thus, as increased social investments reduce the costs of schooling or increase the supply and quality of schooling to families, the magnitudes of the associations between parental resources and children’s schooling decline and become more gender equitable at all ages. However, our results show that older boys may benefit more than older girls from social investments in schooling. These changes suggest potential needs to monitor gender gaps in schooling retention among older children, to insure gender equitable access to social investments in schooling, and to encourage parents to invest in schooling as joint measures to achieve greater schooling achievements of girls and boys.

Kenya studies its schools to identify obstacles for girls. Education and gender

Interviews were conducted with almost 800 adolescents and their parents in 3 districts representing the range of school experience in Kenya. Researchers also visited 36 primary schools attended by more than 80% of the adolescents sampled, holding interviews with teachers and students, documenting facilities, observing interactions, and compiling measures of performance. Boys were seen bullying girls outside of classrooms, teasing them and blocking their movements. In focus group discussions, boys and girls reported that boys routinely grab girls' breasts, while teachers ignore the abuse. Teachers described girls as stupid and lazy, with both male and female teachers who expressed a preference for teaching one sex or the other preferring boys. The teachers more often allocated menial chores to girls and teaching tasks to boys. Even in schools in which girls performed almost as well as boys on exams, teachers awarded twice as many prizes to boys. The teachers created a context in which girls perform poorly. When the girls do in fact fail to achieve, teachers' prejudices are simply reinforced. On the other hand, schools at which girls performed better on exams had more female teachers who presumably served as role models. Also, girls in schools with more female students scored higher on the final, nationwide exam.     

The Implementation of Preferences for Male Offspring

Over the past quarter century the sex ratio at birth (SRB) has risen above natural levels in a number of countries, mostly in Asia. This rise has been made possible in populations with strong son preference by the increasing availability of safe, effective, and inexpensive technologies to determine the sex of a fetus and to end unwanted pregnancies. This article documents levels and trends in the sex ratio at birth, in preferences for male offspring (using information on desired number of girls and boys), and in the implementation of these preferences. DHS surveys from 61 countries in Africa, Asia, and Latin America and for Indian states are the main source of data. A comparison of desired with actual SRBs finds large gaps in most populations, implying a substantial pent‐up demand for male offspring and the technology to implement this preference. Two types of actions to implement preferences are considered: the practice of contraception to stop childbearing after the desired number of sons has been born and the use of sex‐selective abortion to avoid female births. The second part of the article discusses factors that could influence the SRB, including the promotion of gender equality, and the implications of these factors for future trends.     

Gender of children and birth timing

We address the impact of the gender of children on birth timing. Our findings suggest that a preference to balance the gender of children affects the timing of births, not a preference for either sons or daughters. At parity 2, women with children of the same sex time a third birth more rapidly than women with a boy and a girl. At parity 1, women with a boy time second births more rapidly than women with a girl. This seemingly anomalous finding is explained, however, by the fact that women with boys are more likely than women with girls to be married at any point in time and thus less likely to have disrupted fertility careers.     

Education Gains Attributable to Fertility Decline: Patterns by Gender,Period, and Country in Latin America and Asia

We investigate the heterogeneity across countries and time in the relationship between mother’s fertility and children’s educational attainment—the quantity-quality (Q-Q) trade-off—by using census data from 17 countries in Asia and Latin America, with data from each country spanning multiple census years. For each country-year, we estimate micro-level instrumental variables models predicting secondary school attainment using number of siblings of the child, instrumented by the sex composition of the first two births in the family. We then analyze correlates of Q-Q trade-off patterns across countries. On average, one additional sibling in the family reduces the probability of secondary education by 6 percentage points for girls and 4 percentage points for boys. This Q-Q trade-off is significantly associated with the level of son preference, slightly decreasing over time and with fertility, but it does not significantly differ by educational level of the country.     

Fertility decline and gender bias in

Although it is widely acknowledged that the preference for sons is a barrier to a decline in fertility, considerable disagreement exists as to what actually happens to this preference when fertility declines in a region of low female autonomy. By analyzing the data from the National Family Health Survey (NFHS), we present evidence from northern India to show that the preference for sons is reduced when the ideal family size becomes small, even though it does not completely disappear. This finding appears to contradict trends in the juvenile sex ratio and the incidence of female feticide that suggest the intensification of gender bias. We argue that the anomaly is the result of a diffusion of prenatal sex-diagnostic techniques in regions where there is a large unmet demand for such methods. Using the NFHS data, we estimate that in northern India, girls currently constitute about 60% of the unwanted births and that the elimination of unwanted fertility has the potential to raise the sex ratio at birth to 130 boys per 100 girls.     

An Increase in the Sex Ratio of Births to India‐born Mothers in England and Wales: Evidence for Sex‐Selective Abortion

Male preference in many Asian cultures results in discriminatory practices against females, including neglect and infanticide. This preference, together with the availability of prenatal sex determination and sex‐selective abortion, has led to an increase in sex ratios at birth in China, India, and South Korea. The resulting expected gender imbalances raise ethical, demographic, and social concerns. We analyzed birth statistics to see whether similar trends are apparent among births to foreign‐born mothers in England and Wales. Before 1990, sex ratios at birth were consistently nearly one point lower (104) for the three major Asian groups in Britain compared with mothers born in Western countries. This is inconsistent with previous suggestions that Asian populations have a higher “natural” sex ratio at birth. In the birth statistics since 1990, we find a four‐point increase in the sex ratio at birth for mothers born in India, attributable particularly to an increase at higher birth orders, mirroring findings reported for India. This suggests that sex‐selective abortion is occurring among mothers born in India and living in Britain. By contrast, no significant increase was observed for Pakistan‐born and Bangladesh‐born mothers, among whom male preference also exists. It seems that male preference in different cultures does not necessarily lead to sex‐selective abortion.     

Sex Differentials in Undernutrition: A Look at Survey Evidence

This note seeks indirect evidence regarding possible sex biases in food intake for adults and children, through large‐scale survey findings for anthropometric indicators. Among adults, excess female undernutrition is a serious problem in view of the large populations concerned (rural China, India), but data are still needed to assess the situation in many countries. Regarding preschool children, the anti‐female biases once noted for China, India, and other countries seem to have disappeared. Where differences exist, boys fare worse than girls (probably because girls, given a less than adequate food supply, tend to cope with it better than boys). Anti‐female discriminatory practices either are limited in magnitude or apply in groups that are too few or too small to be detectable in large populations.
