Abstract
A reanalysis of a set of data on the sex distribution of children in Japanese families shows that further increase in family-size is related to the sex of the second child (P less than 0.025). When the second child is male, there is a reduced likelihood of further children. This result is consistent with findings from a U.S. fertility study.
摘要
对一组关于日本家庭儿童性别分布的数据进行的重新分析表明，家庭规模的进一步增加与第二个孩子的性别有关（P小于0.025）。当第二个孩子是男孩时，生育更多孩子的可能性会降低。这一结果与美国一项生育研究的结果一致。
