On the other hand, Oakland is also persistently near the top of the list of most dangerous cities in the US. One recent report put it at #2 [1]. That's generally not a good sign.
Is there much interaction between the high income/high education areas (presumably where you'd want to put your start up), and the high crime areas?
BTW, in addition to having one of the highest crime cities in the nation with Oakland, the Silicon Valley area also has one of the lowest. That would be Sunnyvale, which was the 10th on this recent list of safest cities in the US [2].
