Then the graph would imply that there were far more blacks than whites victimized in September 2001, no? Unconfuse me, somebody. "Seems strange for attacks on Manhattan office buildings and the Pentagon," he said, non-racistally. (The peaks seem to occur right at mid-September on the abscissa for 2001.)
No, because the increase due to 911 is the amplitude of the spike, not the absolute value of the spike. So the black rate went fro 23-ish per 100,000 to 31-ish, while the white spike was from 3 to 15-ish per 100,000. Combined with the difference in population size that seems correct at first glance for a 911 victim pool tha was predominantly white.
