As it turned out, the victims of Katrina were not disproportionately poor; they were disproportionately old. Three-quarters of the dead were over sixty, according to the Knight Ridder analysis. Half were over seventy-five. They had been middle-aged when Hurricane Camille struck. “I think Camille killed more people during Katrina than it did in 1969,” says Max Mayfield, director of the National Hurricane Center. “Experience is not always a good teacher.”
