One can see how the population is shifting from these maps, where NOLA is gaining and loosing population.
“Five years after Katrina, 66 of New Orleans’ 73 neighborhoods have recovered well over half of the
population they had before the levees failed, as indicated by households receiving mail in the Valassis
Residential and Business database. …
“Eight neighborhoods now have a larger number of active households than they did prior to the levee
breaches. Seven of these neighborhoods largely did not flood because they are on the West Bank or in
the “sliver by the river.” Gert Town did experience severe flooding, but has more active households than before the storm due to the revitalization of several multi–unit buildings that were vacant when Katrina struck.”
