Using data from the 1980, 1985, and 1990 Current Population Surveys, we show that the link between early fertility and nonmarital births has become stronger. Women who give birth earlier are increasingly likely to be unmarried. In contrast, we find a weaker association between first births at young (versus older) ages and (1) a rapid pace of subsequent childbearing and (2) higher completed fertility. We discuss possible causes and consequences of these changes.
利用1980年、1985年和1990年的当期人口调查数据，我们发现早育与非婚生育之间的联系变得更强了。早育的女性未婚的可能性越来越大。相比之下，我们发现年轻时（相对于年长时）的头胎生育与（1）随后快速生育以及（2）较高的终身生育率之间的关联较弱。我们讨论了这些变化可能的原因和后果。
