Stunning Maps Help Visualize Complex Data

In this map that visualizes segregation of races in New York City, white people are represented by blue dots, African-Americans by green, Asians by red and Latinos by orange.

Income divides aren’t the only measures of metropolitan segregation. As post-racial as we’d all like to believe we are, the fact of the matter is that many neighborhood borders are drawn along racial divides.

Dustin Cable, of the University of Virginia’s Weldon Cooper Center for Public Service, has created a colorful map that vividly illustrates this division. Using 2010 U.S. Census data, the map shows one dot per person, color-coded by race. In all, that’s 308,745,538 dots, or around 7 GB of visual data.

White people are represented by blue dots, African-Americans by green, Asians by red and Latinos by orange. All other race categories from the Census are represented by brown. The above photo is an image of the greater NYC metro area.

It’s not the first map to show every single person, nor is it the first to show ethnic dissemination. It is, however, the first map to do both, making it the most exhaustive map ever created on race in America.

For a truly startling glimpse of how sharp racial dividing lines in American cities can be, be sure to check out Detroit, which is nearly split in half by 8 Mile Road.
