Post-Katrina Survivors: Hometowns vs. Relocations

I found this map in a web article about post-hurricane Katrina Survivors on the following website: http://www.epodunk.com/top10/diaspora/index.html. I find this map interesting because I am originally from New Orleans; I was lucky enough to move before Hurricane Katrina ravaged the Gulf Coast. I have a deep-rooted interest in the aftermath of the storm, and this particular map shows 40,000 post-Katrina survivors' hometowns and where they currently reside. (Hometowns are marked by a white dot in the South and current residences are marked by another white dot elsewhere; these white dots are connected by a black line that give an idea of how far from home some of the survivors were relocated.) I find it interesting that most people relocated to either the East Coast or to Florida because these particular areas of the country aren't necessarily storm-proof. I also could have predicted that not many people would have relocated to the West Coast, as many Post-Katrina survivors did not have the means to travel such a great distance. For that matter, it is not unusual to see that many people relocated in or around the South. I will investigate this phenomena in future posts.
