August 29th is the fifth anniversary of Hurricane Katrina, and now there are some post-Katrina repopulation maps revealing the aftermath of the decimated New Orleans and the surrounding areas.
The New York Times uses data from GCR & Associates that looked at utility, sanitation, mail and voter activity statistics to determine resettlement percentages from 2006 to 2010. This can be seen in their sliding timeline, “Mapping the Recovery of New Orleans.” They have estimated up to 80 percent of the city’s population before the hurricane has returned.
The Greater New Orleans Community Data Center uses the Census block for June 2005 and June 2010 to compare the numbers of residential addresses actively receiving mail in New Orleans. Their site states,”162,115 households received mail in June 2010, in New Orleans, compared to 203,457 in June 2005.”
FEMA has Hurricane Katrina Flood Recovery Maps available, showing “the extent and magnitude of Hurricane Katrina’s surge, as well as information on advisory flood data, were created for areas in southeastern Louisiana parishes that were most severely impacted by coastal flooding.”
