Some statistics I found. More later.
Murder and Gender
In 2011, the United States Department of Justice compiled homicide statistics in the United States between 1980 and 2008. That study showed the following:
Males committed the vast majority of homicides in the United States at that time, representing 90% of the total number of offenders.
Young adult black males had the highest homicide offending rate compared to offenders in other racial and sex categories.
White females of all ages had the lowest offending rates of any racial or age groups.
The overall offending rates for both males and females have declined since 1990.
Of children under age 5 killed by a parent, the rate for biological fathers was slightly higher than for biological mothers.
However, of children under 5 killed by someone other than their parent, 80% were killed by males.
Victimization rates for both males and females have been relatively stable since 2000.
Males were more likely to be murder victims (76.8%).
Females were most likely to be victims of domestic homicides (63.7%) and sex-related homicides (81.7%)
Males were most likely to be victims of drug- (90.5%) and gang-related homicides (94.6%).
