Using nineteen panels of the 1979 National Longitudinal Survey of Youth (NLSY-79), we construct life-lines characterizing women's childless expectations and fertility behavior. One-quarter of women in the NLSY-79 cohort ever reported an expectation for childlessness but only 14.8 percent of women remain childless. Childless women follow two predominant life course paths: (1) repeated postponement of childbearing and the subsequent adoption of a childless expectation at older ages or (2) indecision about parenthood signaled through vacillating reports of childless expectations across various ages. We also find that more than one in ten women became a mother after considering childlessness: an understudied group in research on childlessness and childbearing preferences. These findings reaffirm that it is problematic to assign expected and unexpected childlessness labels to the reproductive experience of childless women. In addition, despite their variability over time, childless expectations strongly predict permanent childlessness, regardless of the age when respondents offer them. Longitudinal logistic regression analysis of these childless expectations indicates a strong effect of childbearing postponement among the increasingly selective group of childless women. However, net of this postponement, few variables commonly associated with childlessness are associated with reports of a childless expectation. We thus conclude that the effects of socio-demographic and situational factors on childless expectations are channeled predominantly through repeated childbearing postponement.
利用1979年全国青年纵向调查(NLSY - 79)的19个样本组,我们构建了描述女性无子女期望和生育行为的生命线。在NLSY - 79队列中,四分之一的女性曾报告过无子女的期望,但只有14.8%的女性保持无子女状态。无子女的女性遵循两条主要的人生轨迹:(1)反复推迟生育,随后在年龄较大时产生无子女的期望;或(2)通过在不同年龄段对无子女期望的摇摆不定报告来表明对生育的犹豫不决。我们还发现,超过十分之一的女性在考虑过无子女后成为了母亲:这是在无子女和生育偏好研究中一个未被充分研究的群体。这些发现再次证实,给无子女女性的生育经历贴上预期和意外无子女的标签是有问题的。此外,尽管无子女期望随时间变化,但无论受访者在什么年龄表达这些期望,它们都能强烈预测永久无子女。对这些无子女期望的纵向逻辑回归分析表明,在越来越具选择性的无子女女性群体中,生育推迟有很强的影响。然而,除去这种推迟因素,很少有通常与无子女相关的变量与无子女期望的报告有关。因此,我们得出结论,社会人口学和情境因素对无子女期望的影响主要是通过反复推迟生育来传导的。
