US Census DotmapSubmitted by Ed Thinking on Sun, 01/27/2013 - 14:50
This is a map of every person counted by the 2010 US and 2011 Canadian censuses. The map has 341,817,095 dots - one for each person.
I wanted an image of human settlement patterns unmediated by proxies like city boundaries, arterial roads, state lines, &c. Also, it was an interesting challenge.
