This study analyzes changes in racial composition, household income, and housing prices across affected parishes, using descriptive statistics and regression models. The findings highlight strong links between flood impacts, population shifts, and housing price dynamics, and propose a replicable framework for monitoring post-disaster recovery.

• Extreme weather-related events increasingly cause displacement globally, with 45.8 million people displaced in 2024. Approximately 1.0-1.9% of US households have been displaced in 2023 by natural disasters.
• Migration strains urban infrastructure and increases vulnerabilities in destination areas.
• Conversely, population loss reduces local tax revenue, impairing community sustainability, disaster recovery, and infrastructure maintenance/investment.
• Migration decisions are influenced by complex personal, socioeconomic, and environmental factors. Barriers such as moving costs and legal restrictions further shape these choices.
• The interaction between demographic changes and housing prices remains underexplored in disaster migration research.
