本文回顾了有关出生性别比决定因素的最新文献。第一部分概述了生物决定因素的主要发现，及其对种族差异和战时出生性别比上升的影响。第二部分讨论出生性别比的社会人口因素（父母年龄、出生顺序和社会经济地位）。审查和比较了约三十项研究，这些研究基于从各国国家人口动态登记统计数据中抽取的数百万出生样本。结果表明，出生顺序和父亲年龄似乎与出生性别比呈负相关。社会经济地位较高的父母可能比社会经济地位较低的父母更有可能生育儿子。对于社会人口因素的影响，提出了一些可能的因果机制。
This paper reviews recent literature on the determinants of the sex ratio at birth. The first part provides an overview of the major findings on the biological determinants, and their implications on the racial differentials and the wartime increases in the sex ratio at birth. The second part discusses the sociodemographic factors of the sex ratio at birth (age of parents, birth order, and socioeconomic status). About thirty studies based on samples of millions of births drawn from national vital registration statistics in various countries are reviewed and compared. The results indicate that birth order and paternal age appear to be negatively correlated with the sex ratio at birth. Parents of higher socioeconomic status may be more likely to bear sons than parents of lower socioeconomic status. Some possible causal mechanisms are suggested for the effects of the sociodemographic factors.
