The denominator in NYC is very high, so poorly on that metric. It might be closer (though I suspect not particularly close) if you compared VC$/square foot, or VC$/engineer.

All these metrics are but approximations of the impossible-to-measure VC$ available/VC$ sought number that actually matters to startups. I suppose we could compare VC$/GDP$, to get some idea of how much of a nation's economy is based on startups.
