Project Summary The proposed study focuses on adolescent childbearing among the U.S. Hispanic/Latina (hereafter: Hispanic) population. Declines in teen fertility in the U.S have been widespread and, in recent years, have been particularly large among Hispanic/Latina adolescents. Given their disproportionate share of teen births (over one-third of all teen births in 2017 were to Hispanic teens), the drop in the Hispanic birth rate accounts for a substantial portion of the recent decline in the national teen birth rate. Beyond birth data reports, however, there has been no formal demographic accounting of these unprecedented declines that considers the vast heterogeneity and significant changes in the Hispanic population. This kind of rich description is an essential, albeit frequently bypassed, step in the broader tasks of identifying the causes (both proximate and distal) of the impressive declines in Hispanic teen fertility. We leverage nearly 30 years of Natality data (1991-2018) to first determine if declines in Hispanic teen birth rates have been widespread or exclusive to particular sub-groups (cross-classified by different combinations of region-of-origin, nativity, geographic location in the U.S., age, and marital status). Second, we employ decomposition analysis to adjudicate between different explanations (i.e. compositional shifts vs. unobserved behavioral changes) behind any documented declines. Together, our approach will reveal patterns that are essential to a more comprehensive understanding of Hispanic teen fertility, including how it has (or has not) changed and the reasons for any observed changes. By identifying sub-groups at continued teen childbearing risk and identifying the sources of observed declines, this study will help inform continuing policy and programmatic efforts focused on adolescent pregnancy prevention.

项目概要 拟议的研究重点是美国西班牙裔/拉丁裔青少年的生育情况 （以下简称：西班牙裔）人口。美国青少年生育率普遍下降， 近年来，这种现象在西班牙裔/拉丁裔青少年中尤为突出。鉴于他们的 青少年出生的比例过高（2017 年所有青少年出生的三分之一以上是西班牙裔 青少年），西班牙裔出生率的下降占了近期下降的很大一部分 在全国青少年出生率中。然而，除了出生数据报告外，还没有正式的报告。 对这些前所未有的下降进行人口统计，考虑到巨大的异质性 以及西班牙裔人口的重大变化。这种丰富的描述是必不可少的， 尽管经常被绕过，但还是要介入更广泛的任务，找出原因（两者都是最接近的） 和远端）西班牙裔青少年生育率显着下降。我们利用近 30 年的经验 出生率数据（1991-2018）首先确定西班牙裔青少年出生率是否下降 广泛存在或专属于特定子群体（通过不同的组合进行交叉分类） 原籍地区、出生地、在美国的地理位置、年龄和婚姻状况）。第二，我们 采用分解分析来裁决不同的解释（即成分 任何有记录的下降背后的转变与未观察到的行为变化）。在一起，我们的 方法将揭示对于更全面地理解至关重要的模式 西班牙裔青少年的生育能力，包括其发生（或未发生）变化以及发生变化的原因 观察到的变化。通过识别青少年持续生育风险的亚组并确定 观察到的下降的来源，这项研究将有助于为持续的政策和计划提供信息 工作重点是预防青少年怀孕。
