yep. here is a nice clip:
The poorest
white neighborhoods experienced murder rates ten times
greater than the richest white neighborhoods; for blacks, the
corresponding ratio was almost twenty to one. It is strik-
ing, however, that the link between income and homicide
weakened substantially over time. For whites, homicide
rates were unrelated to income in the 1986-95 period. In
fact, the very lowest homicide rates were reported in the
poorest white neighborhoods. For blacks, the pattern was
less pronounced. The worst black neighborhoods experi-
enced higher homicide rates in later years, but the rise in
homicides in these neighborhoods was much smaller than
the proportionate increase in the richer black neighbor-
hoods. Murder rates in the 75th to 90th income percentile
more than quadrupled for blacks; rates for the highest 10 per-
cent of blacks more than doubled.
