Meanwhile, I am surrounded by vacant lots, a large mall that is entirely dead and vacant, low income housing, one tiny strip mall with a convenience store, and another with a church, dollar store, and liquor store (a mile away).
I can see though that the OZ tract is tiny, whereas the tract I'm in is about 7 x larger and includes some more supermarkets and malls further away that are very active though not upscale.
Looks like a fairly straightforward case of economic gerrymandering.
