*I made the map above using data from Wikipedia and Oakland Chinatown History (see in-map references). These boundaries were cross referenced with various other sources and check out give or take. I used a circular polygon to indicate a general vicinity where pre-1900 and 1900 settlements were recorded because the boundaries weren't consistently clear over all the sources. The black lines in the Oakland city layer indicate current neighborhood layers. The map is intended to be simple and clear without delving too deeply into history that I could not verify.
