With a developed and dense downtown, the revenue collected per square mile should be higher than revenue per square mile out of suburbs. True, suburban single-family houses are typically more expensive than condos, but as you keep stacking those condos on top of one another, you gain property tax revenue at no loss to square footage.

That's a grand theory, of course. In reality, outside of a few cities, most American urban downtowns are proverbial dumps.
