Ilove maps and I love Oakland, so I was happy when OaklandSeen pointed me to a map of Oakland with 2000 census data by race & ethnicity overlaid. We all know Oakland is diverse, but not equally in all parts.
I took Eric Fischer's Bay Area map from Flickr and overlaid it with the Oakland neighborhoods map to give a better sense of where things are. But even without the overlay, you can pick out some neighborhoods like Chinatown, and geographical areas like Mountain View Cemetery (where there aren't very many living people) and the regional parks.
One surprise to me was how diverse and densely populated the area just north of Lake Merritt is (Adams Point, HarriOak, Grand Lake). Click for the full-size map without the overlay.
