Katrina displaced 800,000 people, contributing significantly to the decline. African Americans, renters, the elderly, and people with low income were disproportionately affected by Katrina, compared to affluent and white residents. In Katrina's aftermath, city government commissioned groups such as Bring New Orleans Back Commission, the New Orleans Neighborhood Rebuilding Plan, the Unified New Orleans Plan, and the Office of Recovery Management to contribute to plans addressing depopulation. Their ideas included shrinking the city's footprint from before the storm, incorporating community voices into development plans, and creating green spaces, some of which incited controversy.
