A lot of strong towns framing uses “financial productivity” defined as tax revenue per unit area, usually acre. Poor neighborhood’s houses may be cheap, but are packed much more densely, leading to higher revenue per unit area. less in taxes per lot, but also lower maintenance costs per lot.
Those lots are probably a quarter the size of the lot I’m on, in a affluent suburban house. Maybe even smaller
Its true that it’s not that dense though.
It’s also pretty likely that there are more residents per house than a typical affluent neighborhood.
