Background: Kolk et al. (2023) use Swedish register data to provide a detailed numerical account of biological kinship. Applying their approach in other countries is challenging due to high data requirements. Objective: We examine whether Kolk et al.’s (2023) findings generalize to another demographically advanced country, the Netherlands, and assess how differences in cohort fertility and divorce rates influence the prevalence of different kin types. Methods: We analyze kinship network data for the entire Dutch population in 2018, focusing on ties to grandchildren, children, nieces, nephews, siblings, cousins, parents, aunts, uncles, and grandparents. Results: First, we find strong similarities between Dutch and Swedish kinship structures, extending the picture drawn by Kolk et al. (2023) to another demographically advanced Western context. Second, we show how the Dutch baby boom has trickled down across generations, leading to larger numbers of aunts, uncles, and cousins. Third, we show how differences in other family-related behaviors – specifically divorce and separation – shape the composition of kinship networks and cross-national differences, evident in a substantially lower number of half-siblings in the Netherlands than in Sweden. Contribution: This replication underlines the benefits of empirically validating kinship statistics derived from microsimulations and aggregate demographic data.

一个平行的亲属宇宙？Kolk 等人（2023 年）与荷兰亲属网络登记数据的复制（Vera de Bel、Eszter Bokányi、Karsten Hank、Thomas Leopold）


背景：Kolk 等人（2023 年）使用瑞典登记数据来提供生物亲缘关系的详细数字说明。由于数据要求高，在其他国家/地区应用他们的方法具有挑战性。目的：我们研究了 Kolk 等人 （2023） 的研究结果是否适用于另一个人口统计先进的国家荷兰，并评估了队列生育率和离婚率的差异如何影响不同亲属类型的患病率。方法：我们分析了 2018 年整个荷兰人口的亲属关系网络数据，重点关注与孙子女、子女、侄女、侄子、兄弟姐妹、堂兄弟姐妹、父母、阿姨、叔叔和祖父母的关系。结果：首先，我们发现荷兰和瑞典的亲属关系结构之间有很强的相似性，将 Kolk 等人（2023 年）描绘的图景扩展到另一个人口统计学先进的西方背景。其次，我们展示了荷兰婴儿潮是如何在几代人中涓涓细流的，导致更多的阿姨、叔叔和堂兄弟姐妹。第三，我们展示了其他与家庭相关的行为的差异——特别是离婚和分居——如何影响亲属网络的构成和跨国差异，荷兰同父异母的兄弟姐妹数量远低于瑞典。贡献： 这种复制强调了实证验证来自微观模拟和聚合人口统计数据的亲属关系统计数据的好处。
