Lessons from Hurricane Katrina for Predicting the Indirect Health Consequences of the COVID-19 Pandemic. 2020.

Proceedings of the National Academy of Sciences

Beyond their immediate effects on mortality, disasters have widespread, indirect impacts on mental and physical well-being by exposing survivors to stress and potential trauma. Identifying the disaster-related stressors that predict health adversity will help officials prepare for the coronavirus disease 2019 (COVID-19) pandemic. Using data from a prospective study of young, low-income mothers who survived Hurricane Katrina, we find that bereavement, fearing for loved ones’ well-being, and lacking access to medical care and medications predict adverse mental and physical health 1 y postdisaster, and some effects persist 12 y later. Adjusting for preexisting health and socioeconomic conditions attenuates, but does not eliminate, these associations. The findings, while drawn from a demographically unique sample, suggest that, to mitigate the indirect effects of COVID-19, lapses in medical care and medication use must be minimized, and public health resources should be directed to those with preexisting medical conditions, their social networks, and the bereaved.


Natural hazards and disasters distress populations and inflict damage on the built environment, but existing studies yield mixed results regarding their lasting demographic implications. I leverage variation across three decades of block group exposure to an exogenous and acute natural hazard—severe tornadoes—to focus conceptually on social vulnerability and to empirically assess local net demographic change. Using matching techniques and a difference-in-difference estimator, I find that severe tornadoes result in no net change in local population size but lead to compositional changes, whereby affected neighborhoods become more white and socioeconomically advantaged. Moderation models show that the effects are exacerbated for wealthier communities and that a federal disaster declaration does not mitigate the effects. I interpret the empirical findings as evidence of a displacement process by which economically disadvantaged residents are forcibly mobile, and economically advantaged and white locals rebuild rather than relocate. To make sense of demographic change after natural hazards, I advance an unequal replacement of social vulnerability framework that considers hazard attributes, geographic scale, and impacted local context. I conclude that the natural environment is consequential for the socio-spatial organization of communities and that a disaster declaration has little impact on mitigating this driver of neighborhood inequality.


The Social Consequences of Disasters. 2020.

Annual Review of Sociology

We review the findings from the last decade of research on the effects of disasters, concentrating on three important themes: the differences between the recovery of places vs. people, the need to differentiate between short and long term recovery trajectories, and the changing role of government and how it has exacerbated inequality in recovery and engendered feedback loops that create greater vulnerability. We reflect the focus of the majority of sociological studies on disasters by concentrating our review on studies in the United States, but we also include studies on disasters throughout the world if they contribute to our empirical and theoretical understanding of disasters and their impacts. We end with a discussion of the inevitability of more severe disasters as climate change progresses and call on social scientists to develop new concepts and to use new methods to study these developments.

In August 2005, Hurricane Katrina caused unprecedented damage, widespread population displacement, and exposed Gulf Coast residents to traumatic events. The hurricane's adverse impact on survivors' mental health was apparent shortly after the storm and persisted, but no study has examined the long-term effects now that more than a decade has transpired. Using new data from a panel study of low-income mothers interviewed once before Hurricane Katrina and now three times after, we document changes in mental health, and estimate the sociodemographic and hurricane-related factors associated with long-term trajectories of mental health. We find that post-traumatic stress symptoms (PTSS) declined at each of the three post-Katrina follow-ups, but 12 years after the hurricane, one in six still had symptoms indicative of probable post-traumatic stress disorder. The rate of non-specific psychological distress (PD) remained consistently higher in all three follow-ups, compared to the pre-disaster period. In full covariate-adjusted models, no sociodemographic variables predicted long-run combinations of PTSS and PD. However, 12 years later, exposure to hurricane-related traumatic events and pre-disaster PD significantly predicted co-occurring PTSS and PD. Hurricane-related housing damage predicted PTSS in earlier follow-ups, but no longer predicted PTSS in the long-term. Furthermore, hurricane related traumatic events significantly differentiated the risk of having persistent PTSS, relative to recovering from PTSS. The results suggest that there is still a non-negligible group of survivors with continued need for recovery resources and that exposure to traumatic events is a primary predictor of adverse mental health more than a decade post-disaster.


Attitudes toward Mass Arrivals. 2018.

Social Science Quarterly

Objective: Disasters can send large numbers of evacuees into new contexts of reception, where attitudes toward them can vary significantly by perceived social distance. To conventional assessment of such distance along racial lines, we add spatial and temporal distance from point of central arrival. Methods: A novel research design combines the natural experiment triggered by Hurricane Katrina with five consecutive Kinder Houston Area Surveys (2006–2010), which gather data on attitudes toward arrived evacuees as well as tract‐level data on residential context. Results: Regression analyses reveal that spatial and temporal distance act similarly to racial distance in predicting negative attitudes toward evacuees. Results also show these effects are moderated by the racial context of incumbents’ residential neighborhoods. Conclusions: Social distance exerts a multifaceted influence on evacuee reception in ways that become especially pertinent in the arrival of communities from large‐scale, urban evacuations.
