Background: Amid low fertility rates in the industrialized world, some subpopulations have maintained high fertility rates. However, it has often been difficult to study these populations due to limitations in extant data sources. Objective: This paper will demonstrate a method of measuring key demographic indicators for Ultra-Orthodox Jews using demographic and language variables in the American Community Survey (ACS). Methods: Comparison of estimates of total fertility rates derived from ACS estimates of Yiddish and Hebrew speakers to related indicators from small surveys of American Jewish populations and data on same-sect fertility in Israel and the United Kingdom validates the use of Yiddish to identify Ultra-Orthodox Jewish respondents in the ACS. Results: ACS-derived demographic estimates for Yiddish speakers closely approximate estimates derived for Ultra-Orthodox Jewish communities using other methods. Ultra-Orthodox Jews in America have high fertility but very low rates of teen fertility and marriage, and fairly egalitarian marriage ages. Ultra-Orthodox Jewish fertility is high but not necessarily uncontrolled. Conclusions: ACS language data can be used to study relatively small subpopulations with unique demographic characteristics. Contribution: Researchers can use ACS language data to study other demographically unique subpopulations or to study Ultra-Orthodox Jews in more detail than was previously possible.

美国的极端正统生育和婚姻：来自美国社区调查的证据（莱曼·斯通）

背景：在工业化国家生育率较低的情况下，一些亚人群仍保持高生育率。然而，由于现有数据源的限制，研究这些人群往往很困难。目标：本文将展示一种利用美国社区调查 (ACS) 中的人口和语言变量来衡量极端正统犹太人关键人口指标的方法。方法：将 ACS 对意第绪语和希伯来语使用者的估计得出的总生育率估计值与美国犹太人口小型调查的相关指标以及以色列和英国同教派生育率数据进行比较，验证了使用意第绪语来识别超生育率的有效性。 ACS 中的正统犹太受访者。结果：ACS 对意第绪语使用者的人口统计估计非常接近使用其他方法对极端正统犹太社区得出的估计。美国极端正统犹太人的生育率很高，但青少年生育率和结婚率很低，而且结婚年龄相当平等。极端正统犹太人的生育率很高，但不一定不受控制。结论：ACS 语言数据可用于研究具有独特人口特征的相对较小的亚群。贡献：研究人员可以使用 ACS 语言数据来研究其他人口统计上独特的亚群，或者比以前更详细地研究极端正统犹太人。
