Brandon Martin-Anderson of the MIT Media Lab mapped every person in the U.S. 308,450,225 of us. From a wide angle, it doesn’t look very different from other density maps. But zoom in and you’ll see a different story.
(Since it’s based on the Census, each dot isn’t an actual address or location. Rather, since Census data is anonymized at the block level, the map is more of a geographic jitter plot.)
