More Blacks Left New Orleans After Katrina

"New Orleans' black population dropped 57 percent a year after Hurricane Katrina, while the white population declined 36 percent, according to an analysis by three demographers of new census data."

"Billed as the 'first full picture' of the mass migration after the hurricane, the analysis also found that New Orleans residents displaced to Houston and other cities were more likely to be black, uneducated and poor."

"By contrast, those who relocated to the city's suburbs were more likely to be white, educated and well-off."
