U.S. economic supports are built on the assumption that hardship is short-term and that families recover quickly once immediate needs are met. This assumption undermines families’ ability to achieve economic stability by ignoring how disadvantage accumulates over time. Cumulative Disadvantage Theory (CDT) posits that early inequities, particularly those rooted in race, poverty, and institutional access, compound across the life course, producing widening disparities rather than convergence. Policies that overlook these processes inadvertently reproduce inequity.
This study applies CDT to examine 22‑year trajectories of material hardship among mothers in the Future of Families and Child Wellbeing Study (FFCWS), testing whether race/ethnicity, and safety‑net engagement predict membership in distinct hardship trajectory groups.
Methods
Data were drawn from all seven waves of the FFCWS (1998–2022), a birth cohort of families in 20 large U.S. cities (analytic sample: 1,662 mothers with complete data). Material hardship was measured at each wave using a composite indicator across domains: food, housing, utilities, medical, and bill‑paying hardship. Mothers were classified into five longitudinal trajectory groups—Never, Recovered, Intermittent, Late Onset, and Chronic—based on timing and persistence of hardship from Waves 2–7. Multinomial logistic regression predicted trajectory membership using the Recovered group as the reference.
Results
The multinomial model predicting trajectory membership was statistically significant, χ²(36) = 645.34, p < 0.001, Nagelkerke R² = 0.357, indicating that structural and demographic factors shaped long‑term hardship patterns. Only a small share of families followed a Recovered trajectory; most experienced persistent, intermittent, or late‑onset hardship. This contradicts policy assumptions that hardship is brief and self‑correcting and instead reflects cumulative processes described by CDT.
Hardship trajectories differed substantially by race. Relative to White mothers, Black mothers had higher odds of being in the Intermittent (AOR = 4.45, p < 0.001), Chronic (AOR = 3.13, p < 0.01), and Late Onset (AOR = 6.15, p < 0.05) trajectories rather than the Recovered trajectory. Hispanic/Other mothers also had higher odds of being in the Intermittent (AOR = 6.37, p < 0.001), Chronic (AOR = 2.84, p < 0.05), and Late Onset (AOR = 13.14, p < 0.01) trajectories rather than Recovered. Safety‑net engagement showed mixed associations. Relative to Recovered membership, SNAP receipt at hardship onset was associated with lower odds of Late Onset membership (AOR = 0.19, p < 0.05), and TANF receipt to higher odds of Chronic hardship (AOR = 3.14, p < 0.01).
Conclusions and Implications
Our findings suggest that hardship accumulates, recovery is rare, and racialized divergence shows current safety‑net programs are not designed to support equitable participation in society. These patterns reflect racialized disparities in long‑term hardship that align with CDT’s expectation that structural inequities accumulate across the life course. Further, the mixed impact of SNAP and TANF supports suggests access to existing benefit programs may not be sufficient to prevent hardship or interrupt cumulative disadvantage. Together, these results underscore the need for equity‑centered policy designs that strengthen the conditions required for full civic participation.
