Thanks for that! So the data from the US News graphic is absolute numbers... I hope I am understanding that wrong. Looking at the FBI data you provided.... can that be real? Please correct me if I am wrong, and I hope I am.
Using the most recent data from the final link you provided (2015) and considering the population base as taken from Wikipedia (2017), so the total population data is off a bit, but not by much:
White population: 223,553,265 & white-on-white murders: 2574 = 1 w-o-w murder per 86,850 people, i.e. ca. 1.15 w-o-w murders per 100,000 population.
Black population: 40,695,277 & black-on-black murders: 2380 = 1 b-o-b murder per 17,098 people, i.e. ca. 5.9 b-o-b murders per 100,000 population.
Am I reading that wrong? I hope so. If not, that is just... horrible. Okay, checking my poverty thesis for possible mitigating factors ... Poverty rate among whites: 9%; blacks: 24% according to KFF. Higher rates of poverty also seem to correlate with more r-o-r murders... Hmm... there is more going on than I can account for and I don't want to go too deep down that rabbit hole right now, it's just too depressing.
That's fair enough. At least you're looking deeper into the statistics now. And yes, I saw that too (absolute numbers versus proportion of population)
Of course, I could go a step further while coming full circle and ask why the cop-on-perp kill percentages differ so drastically by racial demographic (even if we were to ignore actual guilt or lack thereof) or why, despite the similarity in absolute numbers for crimes where the perp is known, the imprisonment rate by demographic also differs so drastically.
And yes, it is depressing. It really really is.
