Abstract

If gender bias is receding, demographic manifestations of son preference should also tend to decrease. The sex composition of US children provides a key barometer of gender preference. In the 2010 US Population Census, Chinese and Asian-Indian families are more likely to have a son after a daughter, consistent with previous research. Korean-American families, by contrast, do not show this same pattern, paralleling recent declines in sex selection observed for South Korea. Non-Hispanic White families have sex ratios within the range of the biologically norm regardless of the sex composition of previous children. We corroborate the 2010 Census data with 2011-2013 birth certificate microdata, which likewise show elevated sex ratios for Chinese and Asian Indians at higher birth orders.

摘要

如果性别偏见正在消退，那么对男孩的偏好的人口统计学表现也应该趋于下降。美国儿童的性别构成提供了性别偏好的一个关键晴雨表。在 2010 年美国人口普查中，华人家庭和印度裔家庭在有了女儿之后更有可能再要一个儿子，这与之前的研究一致。相比之下，韩裔美国家庭则没有表现出这种模式，与最近观察到的韩国性别选择减少相呼应。无论前几个孩子的性别构成如何，非西班牙裔白人家庭的性别比例都在生物学正常范围内。我们用 2011-2013 年出生证明微数据来证实 2010 年人口普查数据，这些数据同样显示，在更高的出生顺序中，华人家庭和印度裔家庭的性别比例更高。
