“People like you” whoa Gerry. Yea they basically sainted a deadbeat fentanyl addict for overdosing while being arrested so if the data went the other way we’d never hear the end of it. I’m just saying us whites have more pressing problems than violent blacks killing us. Interesting nonetheless

Okay, so I have few issues with the analysis.

1. For interracial ratio's, you use the NIBRS, which according to your Twitter thread is a lot more skewed than larger FBI data, both with the Hispanic+White categorization issue showing a roughly 3:1. (Something like 28% vs 10% for whites and blacks respectively for victimization) Further, the NIBRS has weaker national coverage than the later, doesn't? So I can't shake the feel that the FBI is closer to the actual ratio. For example, inquisitive Bird used offender data for a similar questions a month or so back and used FBI crosstabs instead.

Not saying the typical FBI supp. Is sufficient in terms of absolute numbers, common knowledge due department reporting gaps and unsolved cases , but using data on unsolved cases and Cooper's 2008 algorithm, this average of around 1300 annually, rather than 1800, was developed by this guy.

Further, there becomes a smaller disparity, with the ratio being closer to 2:1 than 3:1, though the FBI data fluctuates between the two depending on the year.

2. I really find your baseline of a hypothetical integrated population where black and white victims have the same rate of murder by blacks despite a stranger-nonstranger effect still likely influencing homicide patterns.

More pressingly, Integration fueled by blockbusting and public housing expansion was more disruptive to the status quo (that is the baseline mobility of lower class blacks) than White flight (which if anything maintained such dissimilarity). So while mathematically plausible, your framing of such a scenario in the same light like Murder rates sans medical advancements is misleading. I am mainly focusing on Northern dynamics here, as in the South patterns of segregation by dissimilarity indexes are a different matter for cities, plus the available space for blacks to be concentrated.

2. Not sure why, given the short duration in most places of maintained segregation in this period, that the 70s-80s would be underestimated. Honestly could be missing something here.

3. The whole "reversion to the mean" point I have partial issue with. While pandemic conditions would match 20th century levels, the simple fact is that fluctuations seen in pre-Floyd disruptions like the Ferguson era still dissipated according to the data. Unless there was some sort of institutional resurgence I am unaware of, what the relavant mean to expect is still a debateable here.

The real question is this just another spike that happened to be more severe given the more unusual demographic conditions, or is this long term?

Whites should be a distinct category. If they can't make them all distinct, put hispanics with blacks at least, and then we can see what the real ratios are.

Excellent work. I have been aware of this data for many years - I've always been skeptical of the FBI dataset - Single-offender, single victim reporting is suspect...and the latino-white conflation for offenders, but not victims. Your concise analysis of the buried trends within it is appreciated.

1) You briefly touched on the question of how to apportion unsolved homicides. It could be interesting to develop a model for this - perhaps based on the relative proportions of cold cases since solved via DNA evidence, though this variable may vary over time.

2)The issue of spatial heterogeneity of black and white populations and rates of interracial crime is a tough one. The 'all blacks live near whites but most whites do not live near blacks' creates a denominator problem. Localized analysis might be necessary . The gap is no doubt large.

3) I assume that you are familiar with the NCVS dataset. It undoubtedly gives a more accurate picture of violent crime than the arrest and conviction data, but by it's very nature is useless for homicide. It might be useful to derive a multivariate correlation between the NCVS data and the FBI violent crime data , and use this correlation to estimate the relative under-reporting of violent crime, and use this to estimate the black-white contribution to the unknown offender' homicides. I suspect that a greater proportion of black-offender homicides go unsolved given the witness noncooperation and Bronx-jury effects. Does this proportion vary based on the race of the victim?

4) Interracial rape. Obama's DOJ stopped publishing this data back in '08, for obvious reasons (the infamous 20,000:1 differential). (it was part of the NCVS dataset, but was never re-published) Accurate numbers are difficult to find. The salience of this topic is....obvious? Inquiring minds want to know.

If the basal murder rates were equal, you would expect a per capita interracial murder rate equal to the population ratio, but wouldn’t the victimization ratio be reversed and thus cancel out?

B/W victimization rate assuming equal murder rate:

B rate = [(R) (White pop) (%Black)] / Black pop

W rate = [(R) (Black pop) (%White)]/ White pop

Dividing these gets you %B/%W — the opposite of the murder rate ratio assuming R is equal. Just checking that the 6x figure is just referring to the murder rate and not the adjusted figure with victimization included.

Buddy, if people think it’s bad now, wait, watch, flee cities; survive: Defund the police has been abandoned in favor of new punitive laws meant to hamstring police. CA and now MD and others have instituted new use of force laws that have abandoned the reasonableness test in favor of “necessary “ without defining it or who or when “necessary” would be determined. The law comes with a threat of ten years in prison and sets up a labyrinth of review boards. The effect is to end proactive policing. It is happening now, it is obvious, and there will be a whirlwind to reap.

Steve Sailer compares blacks to nonblacks, as hispanics have historically been lumped in with whites. He comes up in the same ballpark as you with a 9.2:1 ratio: https://www.takimag.com/article/who-needs-facts/

If whites were separated from other nonblacks, I guesstimate that it would be in the neighborhood of 12:1 or even higher.

Dang I’m so glad this is finally getting put out there

Hey DataHazard, you should to a statistic on how cops are more likely to shoot white people than black people. Roland Fryer, a black harvard university professor, assumed that blacks were discriminated against but then did a study and found the opposite: : “Blacks are 23.5 percent less likely to be shot by police, relative to whites, in an interaction” To explain this, the conclusion made is that “cops are more hesitant to shoot a black person because of the perceive media attention”. You can view Larry Elder explain here: https://youtu.be/1xoDvfJK5yE?t=246 I rely on stats and facts
