Demographics

This is a pretty incredible map detailing where all the singles live. In LA and SF there are 40,000+ more single women living in each city. In NY and Chicago, the opposite, 40,000+ more women.

Assuming every time a hook up occurs it involves a guy and a girl...a fairly safe assumption, it is clear the girls on the West Coast are getting a whole hell of a lot more action than the guys, simply because there are fewer of them to go around.

Why to answer Phil's question, are there not groups of cool single girls at the bars in LA? Because there aren't a whole hell of a lot of cool single girls in LA...at least not compared to New York or Chicago. So the answer, from a simple demographic perspective to improving your love life (if you are a guy on the West Coast) is to move east. You'll have three times as many options.
