In the previous post on interracial and intersexual homicide distributions in the US, Kratoklastes and Buzz Mohawk point out these distributions deal with absolute numbers, not rates.
By rate, blacks are 11.4 times more likely to perpetrate interracial homicide than whites are, and others—a mishmash category including Asians, American Indians, and many people of mixed race—are 1.9 times more likely than whites to do so:
Conversely, though, blacks are 2.5 times more likely than whites are to be the victims of interracial murder. Others are 1.2 times more likely to be so:
Again, this concerns a small fraction, 15.7%, of all homicides in the US for which the race(s) of both victim and offender are known. The vast majority of homicide, 84.3%, occurs between members of the same race, broadly defined.
