Abstract
Natural disasters often exacerbate existing socioeconomic disparities within affected communities, with vulnerable populations experiencing severe socio-economic and psychological repercussions. This study investigates the socioeconomic and demographic determinants of building damage severity and psychological distress following Hurricane Katrina in New Orleans. Following the hurricane's impact on August 29, 2005, residents of New Orleans faced significant hardships, with many losing their homes and family members. Utilizing data from the Displaced New Orleans Residents Survey (DNORS), conducted from mid-2009 to mid-2010, this research examines households and individuals living in New Orleans immediately prior to Hurricane Katrina. The study employs multinomial logistic regression and various regression techniques to analyze socio-demographic characteristics including age, gender, race/ethnicity, marital status, homeownership, household income, education level, employment status, insurance coverage, and presence of children, alongside psychological measures such as mental health symptoms, posttraumatic stress, depression, and perceived stress. The results reveal that race, homeownership status, insurance coverage, employment status, presence of children in the household, and the number of household members are key factors influencing the extent of damage and psychological vulnerability experienced by households. These findings underscore the necessity for targeted policy interventions that address systemic inequalities, enhance disaster preparedness, and support vulnerable populations. By adopting an equity-centered approach in disaster planning and recovery that integrates both physical and mental health considerations, policymakers can develop more effective post-disaster recovery strategies and foster more resilient and sustainable communities better equipped to withstand future catastrophes.
