Demographic research has paid much attention to the impact of childhood conditions on adult mortality. We focus on one of the key aspects of early life conditions, sibling group size, and examine the causal effect of growing up in a large family on mortality. While previous studies have focused on low- or middle-income countries, we examine whether growing up in a large family is a disadvantage in Sweden, a context where most parents have adequate resources, which are complemented by a generous welfare state. We used Swedish register data and frailty models, examining all-cause and cause-specific mortality between the ages of 40 and 74 for the 1938-72 cohorts, and also a quasi-experimental approach that exploited multiple births as a source of exogenous variation in the number of siblings. Overall our results do not indicate that growing up in a large family has a detrimental effect on longevity in Sweden.
人口统计学研究十分关注童年状况对成人死亡率的影响。我们聚焦于早期生活状况的一个关键方面，即兄弟姐妹群体规模，并考察在大家庭中成长对死亡率的因果效应。虽然先前的研究主要集中在低收入或中等收入国家，但我们研究在瑞典，在大家庭中成长是否是一种劣势，瑞典的大多数父母都有足够的资源，并且有慷慨的福利国家体系作为补充。我们使用了瑞典的登记数据和脆弱模型，研究了1938 - 1972年出生队列中40至74岁人群的全因死亡率和特定病因死亡率，还采用了一种准实验方法，将多胞胎作为兄弟姐妹数量外生变化的一个来源。总体而言，我们的结果并不表明在瑞典大家庭中成长会对寿命产生不利影响。
