    Census DotMap

    This is a map of every person counted by the 2010 US Census. The map has 308,450,225 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.

    Cool map. It would be nice to have some reference features like roads.

    Very interesting but I agree with Cardinal that some sort of reference point like interstates (and/or state and province boundaries) would be useful. I know that the intent was to see settlement patterns without stuff like political boundaries or roads but personally I would want to know why people moved into the areas they did and the roads might provide a partial answer.

    It would be interesting if you added the info for 2000, 1990, 1980, etc. at the block levels so that one could see the change over time. However, finding all that historic data in a usable format for the entire country doesn't sound like it would be an easy task.

    I make dot density maps like this quite often to illustrate stuff for site selectors. Sometimes the most simple mapping techniques, like dot density, are among the most useful.

    If you reversed the black & white that would remind me of what the country would look like at night.

    No. Just some parts wake up faster than others.
    Broke parts take a little longer, though.

    AIUI they just did it for fun-art and not for a tool. I think it looks cool and fun but wouldn't know how to use it quantitatively. Surely there is an underemployed software person who wants to improve it...
