本文考察了移民到三个经合组织国家（加拿大、英国和法国）的妇女的生育能力，以及移民年龄与本地出生妇女的生育能力有何不同。通过观察那些生育行为既没有被迁移事件打断也没有被自然选择混淆的儿童移民，作者获得了一种独特的视角，将适应过程作为一种机制来解释所观察到的外国和本土出生的生育率差异的变化。作者发现的模式与适应假说大体一致，该假说认为，随着移民习惯了他们的东道国，他们的生育标准开始与当地人口相似，而且平均而言，生育率差异的跨国变化有限。然而，暴露在东道国的影响似乎因原籍国而异，这一发现强调了考虑外国出生人口异质性的重要性。
This article examines the fertility of women who migrated as children to one of three OECD countries—Canada, the United Kingdom, and France—and how it differs from that of native-born women, by age at migration. By looking at child migrants whose fertility behavior is neither interrupted by the migration event nor confounded by selection, the authors obtain a unique perspective on the adaptation process as a mechanism that explains variation in observed foreign and native-born fertility differentials. The authors find patterns that are broadly consistent with the adaptation hypothesis—which posits that as migrants become accustomed to their host countries, their fertility norms begin to resemble those of the native population—and, on average, limited cross-national variation in fertility differentials. The effect of exposure to the host country, however, seems to vary by country of origin, a finding that underscores the importance of taking into account the heterogeneity of the foreign-born population.
