Population recovery in New Orleans after Hurricane Katrina: Exploring the potential role of stage migration in migration systems.

Abstract

In this research brief, we explore how places affected by natural disasters recover their populations through indirect, or "stage," migration. Specifically, we consider the idea that post-disaster impediments (e.g., housing and property damage) in disaster-affected areas spawn migration flows toward and, over time, to disaster-affected areas through intermediary destinations. Taking as our case Orleans Parish over a five-year period after Hurricane Katrina, we show that stage migration accounted for up to about one-fourth of population recovery. We close by discussing the implications, limitations, and potential extensions of our work.
