From The Atlantic:

By Ta-Nehisi Coates
I’ve spent the last couple of months looking at the roots of white supremacists’ policy, and the limits of color-blind policy in addressing its damage. A few weeks back, while debating Andrew over IQ differentials, I cautioned againstcomparisons between blacks and whites which claim to control for income and even wealth:

This is not merely a problem for your local  diversity and sensitivity workshop. It is a problem of wealth and power. When you create a situation in which a community has a disproportionate number of poor people, and then you hyper-segregate that community, you multiply the problems of poverty for the entire community — poor or not. That is to say that black individuals are not simply poorer and less wealthy than white individuals.  Because of segregation, black individuals and white individuals of the same income and same wealth do not live in communities of equal wealth.

I also pointed to sociologist John Logan’s research which points out that, on average, affluent blacks tend to live in neighborhoods with poorer resources than most poor whites. To understand this you must get that African Americans are the most segregated group in American history. Right now, at this very moment, the dissimilarity index — the means by which we measure segregation — is at the lowest point it’s been in a century. Despite that, African Americans are still highly segregated.
To understand the profound consequences of segregation, consider this study by sociologist Patrick Sharkey — “Neighborhoods and The Mobility Gap” — which looks at how children fare when exposed to poverty. The answer, of course, is not well. Instead of trying to do a one-to-one match of African Americans and whites via income or wealth, the study considers African Americans and whites within the neighborhoods in which they live. The conclusions are generally not surprising:

Among children born from 1955 through 1970, only 4 percent of whites were raised in neighborhoods with at least 20 percent poverty, compared to 62 percent of blacks. Three out of four white children were raised in neighborhoods with less than 10 percent poverty, compared to just 9 percent of blacks. Even more astonishingly, essentially no white children were raised in neighborhoods with at least 30 percent poverty, but three in ten blacks were.And more shockingly still, almost half (49 percent) of black children with family income in the top three quintiles lived in neighborhoods with at least 20 percent poverty, compared to only one percent of white children in those quintiles. These figures reveal that black children born from the mid 1950s to 1970 were surrounded by poverty to a degree that was virtually nonexistent for whites.

This degree of racial inequality is not a remnant of the past.

Two out of three black children born from 1985 through 2000 have been raised in neighborhoods with at least 20 percent poverty, compared to just 6 percent of whites. Only one out of ten blacks in the current generation has been raised in a neighborhood with less than 10 percent poverty, compared to six out of ten whites. Even today, thirty percent of black children experience a level of neighborhood poverty — a rate of 30 percent or more — unknown among white children.
