Short-term impacts of 2016 floods on the demographic change and housing prices in the state of Louisiana

This study presents a short‑term assessment of how the 2016 Louisiana floods reshaped demographic patterns and housing market conditions across affected and non‑affected parishes, offering insights highly relevant to disaster risk reduction and recovery planning. Using descriptive statistics, a novel population‑monitoring framework, and multiple regression models, the authors quantify population movements and identify the strongest drivers of post‑flood housing price variation. The analysis shows that White populations declined in most Federal Disaster–declared parishes, while Black or African American and Hispanic or Latino populations increased, alongside a rise in median household income and a redistribution of housing stock. Chapters focusing on housing market dynamics and demographic displacement highlight how flood exposure, NFIP‑documented damage, and racial demographic change jointly shape short‑term recovery trajectories. 

The study recommends that planners and policymakers integrate demographic monitoring with housing market analysis to better anticipate uneven recovery and emerging vulnerabilities. The proposed population‑monitoring framework offers a practical tool for local authorities to identify parishes experiencing rapid population loss or gain, enabling more targeted support in future disaster cycles. Lessons learned emphasise the need to address racial and socioeconomic disparities in post‑disaster mobility, ensure equitable access to recovery resources, and recognise that shifts in minority populations can signal heightened exposure to future flood risk.
