The best comparison I've seen was a graphic that showed how much VC capital had been invested in various U.S. markets into tech companies in 2009. I seem to remember SF/Bay was in the $10-12b range, NYC was second in the $4-5b range. Then Boston at $3-4b, and Chicago at $3b or so....with about 45% of that being one company, Groupon.

Just for laughs I'd like to see a comparison consisting of one measure: average time elapsed between entering a coffee shop and hearing the words "startup," "iterate," "pivot," or "code/coding/ruby/rails" :)

Like the Economists Big Mac index for purchasing power parity, the Latte Index for startups: how many startups are sitting in an average Starbucks.
