Vanhemert explains what makes this map so special:
The map, created by Dustin Cable at University of Virginia’s Weldon Cooper Center for Public Service, is stunningly comprehensive. Drawing on data from the 2010 U.S. Census, it shows one dot per person, color-coded by race. That’s 308,745,538 dots in all–around 7 GB of visual data. It isn’t the first map to show the country’s ethnic distribution, nor is it the first to show every single citizen, but it is the first to do both, making it the most comprehensive map of race in America ever created.
White people are shown with blue dots; African-Americans with green; Asians with red; and Latinos with orange, with all other race categories from the Census represented by brown. Since the dots are smaller than pixels at most zoom levels, Cable assigned shades of color based on the multiple dots therein. From a distance, for example, certain neighborhoods will look purple, but zooming-in reveals a finer-grained breakdown of red and blue–or, really, black and white.
