The literature on the “boomerang effect” (returning to the parental home) is predominantly focused on young adults returning to their parents’ home in response to economic hardship. In this chapter, we study the boomerang effect in the context of divorce by looking at who returns to the parental home after a relationship break-up. The analysis is restricted to individuals with children, as the presence of children in the dissolving household gives an additional dimension to the process of young adults moving back in with their parents. We use register data from Belgium to test the probability of returning to the parental home among individuals who were either married or cohabiting. In addition, we take population heterogeneity into account as we compare the boomerang effect among different origin groups (Belgians, Turks, Moroccans). We find that the boomerang process is highly gendered, with men being substantially more likely than women to return to the parental home. Our results also indicate that migration background plays a less important role, with the exception that fathers of Turkish and Moroccan origin are more likely than others to return to the parental home after separation.
