Young adult internal migration forms a large share of the influx of people into large cities in the developed world. We investigate the role of the residential locations of siblings for young adults’ migration to large cities, using the case of Sweden and its four largest cities: Stockholm, Gothenburg, Malmö/Lund, and Uppsala. We use register data for the full Swedish-born population of young adults aged 18–28 living in Sweden in the years 2007–2013 and multinomial logistic regression analyses of migrating to each of the four cities or migrating elsewhere versus not migrating. Our point of departure is the paving-the-way hypothesis, which posits that young adults who have a sibling living at a migration destination are particularly likely to move to that destination, more so than to other destinations. Additional hypotheses are related to having more than one sibling in the city and to the gender of siblings living at the destination. We find support for the paving-the-way hypothesis and an additional effect for having more than one sibling in the city. Having a sibling of the same gender in a city matters more for moving there than having a sibling of the opposite gender.

瑞典年轻人向城市迁移：兄弟姐妹会铺路吗？

年轻的国内移民在涌入发达国家大城市的人口中占很大比例。我们以瑞典及其四个最大的城市斯德哥尔摩、哥德堡、马尔默/隆德和乌普萨拉为例，调查了兄弟姐妹居住地对年轻人迁移到大城市的作用。我们使用了 2007 年至 2013 年间居住在瑞典的 18 至 28 岁年轻人的全部瑞典出生人口的登记数据，以及迁移到四个城市中的每一个城市或迁移到其他地方与不迁移的多项逻辑回归分析。我们的出发点是铺路假说，它假设有兄弟姐妹住在移民目的地的年轻人特别有可能搬到那个目的地，而不是其他目的地。其他假设与在城市中有一个以上的兄弟姐妹以及居住在目的地的兄弟姐妹的性别有关。我们发现对铺路假说的支持以及在城市中拥有多个兄弟姐妹的额外影响。在一个城市里有一个同性的兄弟姐妹比有一个异性的兄弟姐妹对搬到那里更重要。
