The Racial Dot Map is created by the Demographics Research Group at Weldon Cooper Center for Public Service at the University of Virginia. It uses data from the United States Census in 2010 and provides an accessible visualization of geographic distribution, population density, and racial diversity of the American people in every neighborhood in the entire country. There are 308,745,538 dots in the map, one for each person and their location as they were counted during the Census in 2010. The dots are color-coded by race; White, Black, Asian, Hispanic, Other Race (Native American / Multi-racial).
The map shows the vast differences in population densities across the United States. Each of the 308 million dots are smaller than a pixel on your computer screen at most zoom levels. Dots are resolvable at city and neighborhood zoom levels. The map gives a clear indication of the United States demographic landscape from the densely populated eastern seaboard to the sparsely populated Great Plains and on to the mountainous and desert landscapes before reaching the populated west coast of California, Oregon and Washington State.
