You can find figures on how many Blacks are killed by Blacks vs non-Blacks. You can find how many Blacks are killed by men vs women. You can find how many men are killed by Blacks vs non-Blacks. But trying to find how many Black women are killed by Black men is difficult. Obviously the information exists, but I can’t find it with a cursory search.
What I did find was that “Among black marital partners, wives were just about as likely to kill their husbands as husbands were to kill their wives: 47% of the victims of a spouse were husbands and 53% were wives.”
