The family life courses of immigrants and their descendants have been widely studied as indicators of societal integration. But largely absent are investigations into the role of cohabitation in the family lives of these subpopulations. Using Norwegian register data on individuals who were either native born or who immigrated before age 18, we analyse the formation of first cohabiting and marital unions. Next, we compare associations between endogamous or exogamous partner choice and transitions from these first unions. Results showed that the children of immigrants were less likely to cohabit endogamously, but overall more likely to cohabit exogamously and to marry than Norwegians without a migration background. Endogamous migrant-background cohabiting unions were least likely to dissolve, whereas cohabiting couples involving one or two majority partners were less marriage prone than endogamous migrant-background couples. Similarly, among those married, endogamous migrant-background couples were less likely to divorce than their exogamous counterparts.

移民及其后代的家庭生活历程作为社会融合的指标被广泛研究。但对同居在这些亚群家庭生活中的作用的调查基本上没有。我们使用挪威出生或 18 岁之前移民的个人的登记数据，分析了第一次同居和婚姻结合的形成。接下来，我们比较内婚或外婚伴侣选择与这些第一次结合的转变之间的关联。结果表明，与没有移民背景的挪威人相比，移民的孩子不太可能同居同居，但总体而言，同居异婚和结婚的可能性更大。内在的移民背景同居工会最不可能解散，而涉及一两个多数伴侣的同居夫妇比同居移民背景的夫妇更不容易结婚。同样，在已婚的、有同居移民背景的夫妇中，离婚的可能性低于外婚配偶。
