由于Guttentag和Secord提出低性别比例（即，尽管在妇女（男性数量少）和妇女（男性数量少）的情况下，婚姻不稳定和非婚怀孕率高，但对这一问题的实证调查得出的结果既薄弱又相互矛盾。这项研究试图利用联合国汇编的跨国数据澄清这一问题。地理区域、人均国民生产总值（GNP）、结婚率以及样本是城市还是农村被用作回归分析的控制变量，该分析使用性别比例来预测青少年生育。该模型解释了青少年生育率67%的方差。在农村样本和美洲，青少年生育率明显较高，与15至19岁人口的性别比例和国民生产总值呈负相关。正如Guttentag和Secord假设的那样，数据表明早育在一定程度上是对婚姻机会不佳的反应。
Since Guttentag and Secord proposed that low sex ratios (i.e., scarcity of men) produce marital instability and high rates of nonmarital pregnancy, empirical investigations of this issue have produced weak and conflicting results. This study sought to clarify the issue using cross-national data compiled by the United Nations. Geographical region, per capita gross national product (GNP), the marriage rate, and whether the sample was urban or rural were used as control variables in regression analyses which used sex ratios to predict teen births. The model explained 67% of the variance in teen birth rates. Teen births were significantly higher in rural samples and in the Americas and were inversely correlated with the sex ratio for 15- to 19-year-olds and with GNP. The data suggest that early childbearing is partly a response to poor marital opportunity, as Guttentag and Secord hypothesized.
