Housing has received little attention in the research on teen mothers. A qualitative longitudinal study presented a unique opportunity to examine how teen mothers house their families over time. The study began in 1988 and has followed teen mothers and family members for 7 waves over 28 years. The 7th wave began in 2016. The specific aims of this substudy were to describe the housing trajectories of teen mothers over 28 years and to explore how their housing trajectories were shaped by family resources, housing programs, and discrimination. Data from 9 families were analyzed using interpretive phenomenology-. [lousing instability was pervasive for Black mothers who were disadvantaged as children. Their stories included many moves, doubling up, sending children to live with others, depression, unreliable partners, and racism. [lousing instability was a source of toxic stress, interrupted personal and family goals, undermined family routines, and reflected a legacy of discriminatory housing policies. In contrast, White advantaged mothers were stably housed as children and adults, Which reflected longstanding family resources, stable marriages, husbands' steady employment, and tax deductions for homeownership. These stark differences in housing trajectories reflect and reproduce multigenerational social and health inequities. Public Policy Relevance Statement Housing has received little attention the vast research on teenage mothers. In this multigenerational, longitudinal study, stark differences in the housing trajectories of the more advantaged, White families and the disadvantaged Black families reveal how systemic inequities are reproduced over time. These longstanding inequities call for an expanded and universal housing voucher program modeled on other developed countries.
