Table 1 Found Dead Bodies in New Orleans

The total views are indicated in the following Figure 2, 3, 4, and Table 2.
Concerning the population change, New Orleans is the one of the decreasing communities in US. For example, rapid urbanization related matters caused environmental degradation before the disaster. Campanella(2004)mentioned New Orleans became not a sustainable, but a survival city. The lower 9th ward, for example, with regard to the ethnicity, we can see the high black and the African American proportion.  With respect to Income, we can also identify the people living in the Lower 9th ward have lower incomes.
