This study investigates the effects of the Deferred Action for Childhood Arrivals (DACA) on the living arrangements and housing behavior of undocumented immigrants in the U.S. Using an event-study approach and difference-in-differences (DID) estimates, we compare immigrants above and below eligibility cutoffs and demonstrate that after the adoption of the policy in June 2012, DACA-eligible immigrants were less likely to live with their parents or in multigenerational households (-11%) and more likely to live independently (+15.5%). We also reveal that DACA-eligible immigrants were less likely to live in the same house (+2%) and more likely to move out of ethnic enclaves (-3%). Lower rental costs (-4.5%) may have facilitated this transition into adulthood and the observed trends in living arrangements. DACA also led to a decline in marriage rates among DACA-eligible individuals, while we found no evidence of significant effects on cohabitation, divorce, and intermarriage. We also found no evidence of a clear impact on fertility.
