The Philadelphia Inquirer had a fine story on January 2, 2006 which reported the Katrina dead were no poorer, on average, than the residents of the New Orleans area as a whole. Kudos to the Inquirer for giving its readers some pure unalderated analysis and reporting based on facts!
Here are some money quotes from the story: "Four months after Hurricane Katrina, analyses suggest that some widely reported assumptions about the storm's victims were incorrect.
For example, a comparison of the locations where 874 bodies were recovered with U.S. Census tract data indicates that the victims were not disproportionately poor.
Another database, compiled by Knight Ridder of 486 Katrina victims from Orleans Parish and neighboring St. Bernard Parish, suggests they also were not disproportionately African American." Below is the link to the story; I recommend you read it.
