We document a novel fact about neonatal death, or death in the first month of life. Globally, neonatal mortality is disproportionately concentrated in India. We identify a large effect of birth order on neonatal mortality that is unique to India: later-born siblings have a steep survival advantage relative to the birth-order gradient in other developing countries. We show that India's high prevalence of maternal undernutrition and its correlation with age and childbearing can explain this pattern. We find that Indian mothers exit the underweight body mass range at an internationally comparatively high rate as they progress through childbearing careers.
我们记录了一个关于新生儿死亡(即出生后第一个月内死亡)的新事实。在全球范围内,新生儿死亡率不成比例地集中在印度。我们发现出生顺序对新生儿死亡率有很大影响,这在印度是独一无二的:与其他发展中国家的出生顺序梯度相比,后出生的兄弟姐妹有明显的生存优势。我们表明,印度孕产妇营养不良的高流行率及其与年龄和生育的相关性可以解释这种模式。我们发现,随着印度母亲生育历程的推进,她们以国际上相对较高的比率摆脱了体重不足的身体质量范围。
