Here is some relevant data for you from the Bureau of Justice Statistics:

Of particular interest, “Poor urban blacks (51.3 per 1,000) had rates of violence similar to poor urban whites (56.4 per 1,000).”

Asians don’t generally live in multi-generational poverty or in ghettos for many generations. Black people do. White people in the rural parts of Appalachia are rural, and obviously, crime is going to be far more widespread in urban neighborhoods where poor people are clustered together in shabby rat cages, i.e., housing projects, etc., constantly bumping into each other every day in both positive and negative ways, hanging out on street corners, etc. When you live in a rural neighborhood, you’re sitting at home watching t.v. or sitting on your front porch and maybe occasionally seeing others drive by. That’s not an environment in which crime is going to take place. So you have to compare apples to apples, and as I said, the question of whether poverty results in crime or crime (and other dumb and counterproductive behaviors) results in poverty is a complex chicken-and-egg problem, which is why you often hear talk of poverty as a vicious cycle that’s hard to break out of. In the particular case of African-Americans, I find it to be an additional complex issue due to the undeniable history of slavery and race-based discrimination, which resulted in African-Americans starting off with one foot already in poverty, as it were. So I think it’s a difficult question to judge, and it’s frankly not something I’ve look into in great depth as yet (though, of course, I’ve read many things going in both directions), so I’m not prepared to endorse any stark conclusions one way or the other.
