Birth Spacing and Fertility in the Presence of Son Preference and Sex-Selective Abortions: India's Experience Over Four Decades

Mother's age at marriage and gender-differential in child schooling: Evidence from Pakistan

In this study, we provide empirical evidence in support of intergenerational effects of women's marriage age on girl-specific child education outcomes using a nationally representative household survey of 24,809 households from Pakistan. Our key findings are four-fold: First, we find that mother's age at marriage has no girl-specific impact on the education of children of school going age in terms of school enrolment, type of school (public/private) or education expenditure. However, there is a positive effect of delaying mother's marriage on girls in terms of relative grade progression and primary school attainment, implying that late-marrying mothers are more likely to transfer their human capital advantages/disadvantages to the daughters. Second, the impact does not depend on whether the child is firstborn or later-order, youngest child or with no siblings. Sex of the previous child does not affect the relationship either. Third, the beneficial impact of mother's marriage age on girls' education is visible only in the cohort of women who got married in 2000 or later. Fourth, father's marriage age is significantly associated with an increase in daughters' school enrolment and primary completion. The impact of smaller spousal age difference is also positive. These findings are robust to the use of empirical strategies and specifications that address potential endogeneity, collider bias, recall bias, sample selection and confounding factors. These findings suggest that delay in women's marriage is helping to narrow down gender disparities in education. The findings underscore the need to promote social and behavioural changes that encourage later marriages.

Factors influencing sex ratio at birth in Krosno, Poland

The secondary sex ratio (SSR) is a widely used descriptor that reflects the living conditions and health status during pregnancy. The aim of study was to assess the impact of maternal factors, season of birth, and air pollution with the heating season on the sex ratio at birth in the Subcarpathian population from the Krosno district, Poland. A retrospective study involving 11,587 births was occurred at the John Paul II Podkarpackie Province Hospital in Krosno between 2016 and 2020. Sex of the newborn, the season of their birth, as well as the maternal age, birth order, the interval between births, and the season of birth were analysed. Furthermore, the relationship between the SSR and the level of air pollution during the heating season was investigated. To determine the significance of differences in sex ratios, chi-square analysis and multifactorial regression were used, with a significance level set at p < 0.05. At the chi-square level, all the studied factors indicated a statistically significant relationship with the SSR. However, the regression model used shows that maternal age and birth order were the most important factors in shaping the SSR in the study group.
