What's the Opposite of Gentrification?

Pilparinen says that the gentrification model is "way out of whack" in the Rust Belt, where African-Americans are leaving the inner city for the depressed housing market of the suburbs:

"In fact, in terms of creating mixed neighborhoods, this is usually the model-turning the talking points of gentrification on its head," writes Pilparinen.

Mixed neighborhoods are increasing and becoming the norm, he writes:

"The link between generational tolerance and neighborhood change is that altered perceptions lead to changed behaviors and thus new experiences. These experiences: they go from person to person, which then are rapidly leading to the increased prevalence of everyday between-race interactions if not multi-racial nuclear family units. Slowly, then, the creation of integrated neighborhoods ensue that evolve more organically than the colonialist model of gentrification states."
