We’ve been talking quite a bit about racial divides in this town of late, and so its with some interest that we stumbled upon this very interesting map, created by Eric Fischer. Using the same technique and data set as this map of Chicago by Bill Rankin, Fischer mapped several American metropolitan areas. Each dot on the map represents 25 people and their self-identified ethnicity in the 2000 Census (red is White, blue is Black, green is Asian, orange is Hispanic). We’ve gone ahead and added the most basic of boundaries — the District line — so that you can see D.C. clearer.
