Ghetto

Each dot represents 25 people, and each color represents a self identified race from the 2010 census. This is Chicago, and you can see how the main ethnicities are ghettoized. Not specific to Chicago, either, as all American cities and probably most world cities are set up the same way. Here's a few more:

Detroit

LA

Greater NYC.

As long as such ghettoization exists, then so too will racism. But much of it is self chosen, yeah?

Complicated subject!
