Race in Rochester

Today I came across a very interesting series of maps created by Eric Fischer. He used 2000 census data to map major US cities by race. What was striking was the level of segregation that persists is nearly all American cities today. Here is what Rochester's racial map looks like:

The red dots represent whites, the blue dots are blacks, orange are hispanics, and green are asians. Each dot represents 25 people. You can look at racial maps for other US cities here.
