Effet de beigne dans les villes aux USA

[Malek]

This does seem to have some validity in older cities like Boston, New York, Philadelphia, or Chicago, but in newer cities it is not the case. Instead of donuts, one finds "wedges" of wealth occupying a continuous pie-slice from the center to the periphery.

 

Just from visual inspection, it also seems that poverty donuts all tend to have about a five-mile radius, regardless of the size of the city. Perhaps this is the practical limit for commuting without a car?

 

All maps are at the same scale, and all use the same color values for income.
