This map offers a picture of where Philly's unspoken boundaries are, or were, in 2010. This is a map based on 2010 Census data that's color coded by race: the map actually shows the entire country, but can also be zoomed in to different areas.
On the map, Asian people are represented by red dots, Latinos by red dots, Black people are represented by green dots, and white people are represented by blue dots. One wonders what the map would look like now, three years later.
