The demographic characteristics of homicide victims and offenders differ from the general population
Based on data for the years 1976-2005 -
Blacks are disproportionately represented as both homicide victims and offenders. The victimization rates for blacks were 6 times higher than those for whites. The offending rates for blacks were more than 7 times higher the rates for whites.
Males represent 77% of homicide victims and nearly 90% of offenders. The victimization rates for males were 3 times higher than the rates for females. The offending rates for males were 8 times higher than the rates for females.
Approximately one-third of murder victims and almost half the offenders are under the age of 25. For both victims and offenders, the rate per 100,000 peaks in the 18-24 year-old age group.
