Benefits And Detriments of Disaster-Related Shifts in Neighborhood Poverty

Abstract

Recent decades have witnessed the increasing spatial concentration of poverty and affluence in the United States (Biscoff & Reardon, 2013). Given well-documented links between neighborhood economic contexts and wellbeing (Chow et al., 2005), this has the potential to exacerbate disparities in health, particularly for people with limited neighborhood choice. However, limited research has systematically examined the neighborhood features underlying these links. A more nuanced understanding of why neighborhood poverty matters is essential for promoting equitable neighborhood development. Using rigorous analytic techniques that account for the dynamic nature of neighborhoods and help adjust for selection bias, I considered two complementary questions: 1) do observed neighborhood resources and stressors mediate associations between neighborhood poverty and wellbeing within and between individuals; and 2) how do observed versus perceived changes in neighborhood features mediate links between neighborhood poverty and wellbeing? I combined individual-level longitudinal data from the Post-Katrina Study of Resilience and Recovery with administrative neighborhood data drawn from the Census Bureau, FBI, and EPA. Analyses focused on a sample of 606 participants – primarily young Black mothers with low levels of income – who were affected by Hurricane Katrina, most of whom experienced some period of forced relocation. Participants were surveyed once before (2003/04) and twice after (2006/07; 2009) the hurricane. Results paint a complex picture. Contrasting with prior research, total effects of neighborhood poverty on wellbeing were limited. However, changes in neighborhood poverty were linked to wellbeing indirectly through intermediary neighborhood features, with results pointing to benefits and detriments of rising neighborhood poverty. Results were driven by those who changed neighborhoods over the course of the study. For participants that lived in the same New Orleans neighborhood across waves, changes in neighborhood poverty proved less consequential. Overall, results suggest that rather than treating neighborhood poverty as uniformly problematic for wellbeing, efforts to promote health equity should identify and build upon existing assets of neighborhoods, like affordability and amenity access, while also reducing stressors.
