Still doesn't get you into more choice than NYC.
If you don't want to use head count (and I agree there is nuance), what do you want to use? Thus my citation needed request.
The vast majority of software developers work in IT departments writing line-of-business applications in Java, .Net, etc. Certainly NYC has a vast number of these jobs. But these roles are all very similar. You're working as a cost-center, in a supporting role, for people who ultimately don't care about software. This is true whether you're a developer for Pfizer or Jet Blue or NBC Universal or any of the other companies based in
I really find the hollywood analogy apt. Yes, you can certainly find work as an actor in NYC. But the epicenter of the industry is in Hollywood.
Anyway, happy new year!
Edit: Also, counting the total headcount of ppl writing code in the area is not a measure of how many choices you have in the job market.
