Mapping US urban income
On radicalcartography Bill Rankin has produced some interesting maps of urban wealth patterns in large US cities, which show how patterns of wealth and poverty vary among US cities.
Maps show the distribution of income (per capita) around the 25 largest metropolitan areas in the US (all those with population greater than 2,000,000). The goal was to test the “donut” hypothesis — the idea that a city will create concentric rings of wealth and poverty, with the rich both in the suburbs and in the “revitalized” downtown, and the poor stuck in between.
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.
