The Neighborhood Is Mostly Black.
The Home Buyers Are Mostly White.

Nationwide, the arrival of white homeowners in places they’ve long avoided is jolting the economics of the land beneath everyone.

This is title of an interesting and disturbing article from today's NYTime's showing that Detroit reflects a national trend of Euro-American repopulation of urban cores with non-Euro-American movement to suburbs.

The article focuses on Raleigh, NC but reflects the situation here. [Midway through the article a google map allows search of the entire country, from which I drew the first illustration.]

White flight and white return are not opposite phenomena in American cities, generations apart. They are part of the same story.

In the places where white households are moving, reinvestment is possible mainly because of the disinvestment that came before it. Many of these neighborhoods were once segregated by law and redlined by banks. Cities neglected their infrastructure. The federal government built highways that isolated them and housing projects that were concentrated in them. Then banks came peddling predatory loans.

“A single-family detached house with a yard within a mile of downtown in any other part of the world is probably the most expensive place to live,” said Kofi Boone, a professor at North Carolina State University’s College of Design.

Here, because of that history, it’s a bargain. And while that briefly remains true in South Park, the disinvestment and reinvestment are visible side by side on any given street.

All this made me reflection donut between the outer blue and inner orange that appear to be areas of stagnation of no little interest to migrants.
