Intimate partner homicide among blacks is much higher than that of other groups

It's hard to find good stats on racial differences in intimate partner violence since this is the kind of information that makes blacks look bad. One way around this problem is to focus on the easily available homicide victim statistics. We can learn about race and perpetrating domestic violence with victim stats for two reasons: 1) at least 90% of homicides are intra-racial (within a race) so if the victim is black, the perp is too. (And when crimes are interracial, they are more likely to be black-on-white than the reverse); and 2) if a woman is killed, it's usually by a man with whom she had some kind of relationship: a boyfriend, husband, ex, or on the rare occasion, a John.

The CDC has a great website for analyzing mortality data. I generated female homicide rates for race and Hispanic status:

2018 homicide victimization rates (per 100k)

Black  6.3
American Indian  4.4
Hispanic  1.9
White 1.8
Asian  1.0

So the victim rate for black women is 6.3 times that of Asian women,  and 3.5 times that of whites. While these racial gaps are large, they are not as big as those for men (39.0 for blacks and 3.7 for whites). The male-male dynamic--killing for vengeance or saving face--seems to separate blacks and others more than the intimate partner dynamic: the man kills the woman out of jealousy, a desire to get his way, or to punish the victim.

UPDATE: Am I right in thinking that black men and women spend less time around each other in a relationship context than males and females in other groups?  If I'm right, the racial gap in domestic violence would be even larger if we adjusted for time spent together because more exposure to someone increases the risk of violence.
