Dollar Density

Here's a quick reprise of the 3D density map from a while back.  Rather than each person taking up the same amount of 3-dimensional space, each dollar of household income takes up the same amount of space.  The color of the census tract indicates the median household income, with red being lower and green being higher.  So red tracts that are tall have lots of dollars, but a low median income (aka a high density of people that those dollars are divided among).

Excellent comment from Jim Bacon at baconsrebellion.com:

"The map vividly portrays the overwhelming economic dominance of the Chesapeake Crescent in Virginia’s economy — and Northern Virginia’s dominance within the crescent."
