We examine the fertility impact of a family-based regularization policy granting temporary legal status to unauthorized immigrants based on their offspring’s citizenship. The policy, enacted through a 2011 Royal Decree in Spain, allows for unauthorized parents of eligible nationalities to become temporary legal residents if they have a Spanish minor. Using data from the Spanish Labor Force Survey (2007–2016), along with a quasi-experimental approach that exploits the change in legal residency eligibility requirements, we show that the policy has significantly increased the childbearing likelihood of eligible mothers, even though the overall increase in fertility nationwide remains trivial.

基于家庭的正规化对生育能力的影响

我们研究了基于家庭的正规化政策根据其后代的公民身份授予非法移民临时合法身份的生育影响。该政策是通过 2011 年西班牙皇家法令颁布的，允许具有合格国籍的未经授权的父母在他们有西班牙未成年人的情况下成为临时合法居民。使用西班牙劳动力调查（2007-2016）的数据，以及利用合法居住资格要求变化的准实验方法，我们表明该政策显着增加了符合条件的母亲的生育可能性，尽管总体全国生育率的提高仍然微不足道。
