Background: The political and economic change accompanying the collapse of the Soviet Union triggered a large wave of immigrants to Israel during the 1990s. These immigrants arrived from low-fertility contexts to a higher-fertility society. Objective: We consider how the fertility of cohorts of diverse immigrant women from a low fertility context shifts in the context of high fertility. Methods: We examine completed fertility, parity distributions, and age at first birth of immigrant women compared to native-born Jewish women. Data taken from the Israel Population Register and from Israel Social Surveys are examined by birth cohort, religion, and religiosity. Results: We document increases in completed fertility, proportions at final parity 3, age at first birth, and rapid reductions in proportions at final parity 1, across birth cohorts of immigrants who arrived between their early 20s and their early 30s. Rates of change slowed across cohorts of immigrants who arrived between ages 10–21. Relative to comparisons between all Jewish immigrants from the Former Soviet Union and all native-born Jews, there is much closer convergence between secular immigrants and the secular native-born in terms of completed fertility, but substantially less convergence in terms of age at first birth. We also describe strikingly different patterns of change among immigrants who are not classified as Jewish. Contribution: Patterns of immigrant convergence in fertility patterns vis-à-vis native-born groups differ markedly by religion and religiosity. Our findings highlight the importance of explicitly considering heterogeneity among immigrant and native-born groups.

前苏联移民到以色列的群体生育率（Gustavo Shifris、Barbara S. Okun）

背景：20世纪90年代，伴随苏联解体而发生的政治和经济变革引发了以色列的大规模移民潮。这些移民从低生育率的环境来到高生育率的社会。目标：我们考虑来自低生育率背景的不同移民妇女群体的生育率如何在高生育率背景下发生变化。方法：我们比较了移民女性与本土出生的犹太女性的完整生育率、胎次分布和第一胎年龄。从以色列人口登记处和以色列社会调查中获取的数据按出生队列、宗教和宗教信仰进行了检查。结果：我们记录了 20 岁出头到 30 岁出头的移民出生群体的完整生育率、最终胎次比例 3、初产年龄和最终胎次比例 1 的快速下降。10 至 21 岁之间抵达的移民群体的变化速度放缓。相对于所有来自前苏联的犹太移民和所有本土出生的犹太人之间的比较，世俗移民和世俗本土出生的犹太人在完成生育率方面有更接近的趋同性，但在第一胎年龄方面的趋同性要低得多。我们还描述了不属于犹太人的移民之间截然不同的变化模式。贡献：移民与本地出生群体的生育模式趋同模式因宗教和宗教信仰而显着不同。我们的研究结果强调了明确考虑移民和本土出生群体之间异质性的重要性。
