Drawing on life-history interviews, this study explores the impact of Hurricane Katrina in the lives of 57 low-income, African American mothers who were 20-31 years old at the time of the storm. Hurricane Katrina massively disrupted the social networks upon which these mothers relied to facilitate life transitions and make ends meet. The literature would predict that the loss of these important supports would hinder the respondents' transition-to-adulthood experiences. To the contrary, those who relocated away from social ties were more likely than those who returned to report qualitative improvement across life domains. Relocators credited Hurricane Katrina with affording them structural opportunities that lead to a greater sense of independence, a fundamental component of adulthood. This work contributes to our theoretical understanding of the role of familial support during the transition to adulthood.
