Moving into a joint household is an important step in the process of union formation. While a growing body of literature investigates differences between those couples who start coresidence and those who do not, we know little about the likelihood of moving upon the start of coresidence. The aim of this paper is to investigate how individual and couple-level characteristics are associated with moving, or having a partner move in, at the start of coresidence. We use data from 10 waves of the German Family Panel pairfam for those who started coresidence (n = 983) and estimate logistic regression models of moving versus having a partner move in. The respondents in the sample are quite young with a mean age of 27. For long-distance relationships, those with a higher level of education than their partner and women who were living in close proximity to their parents were less likely to move. In short-distance relationships, respondents living in the parental home or in crowded housing were more likely to move than those living in uncrowded housing. In contrast with previous research, we did not find that women were more likely to move than men. Our results highlight that factors like educational resources, housing demands, and local family ties have differential effects on moving decisions at the start of coresidence depending on the distance moved.

搬入联合家庭是组建工会过程中的重要一步。虽然越来越多的文献调查了开始同居的夫妇和没有同居的夫妇之间的差异，但我们对开始同居的可能性知之甚少。本文的目的是研究个人和夫妻层面的特征如何与在同居开始时搬家或让伴侣搬进来相关联。我们使用来自德国家庭小组 pairfam 的 10 波数据，用于那些开始同居（n = 983) 并估计搬家与有伴侣搬家的逻辑回归模型。样本中的受访者非常年轻，平均年龄为 27 岁。对于异地恋，受教育程度高于伴侣和女性的人住在父母附近的人不太可能搬家。在短距离关系中，居住在父母家或拥挤住房中的受访者比居住在不拥挤住房中的受访者更有可能搬家。与之前的研究相比，我们没有发现女性比男性更有可能搬家。我们的研究结果强调，教育资源、住房需求和当地家庭关系等因素对同居开始时的搬家决定有不同的影响，具体取决于搬家的距离。
