I found an interesting map recently. It shows the US with its cities coded by colour and size to show whether single men outnumber single women or vice versa. The results are quite interesting. Rather than showing a random distribution, there is instead a very clear East v West split. It's as though at some point in their lives, men go west and women go east.
I wasn't surprised that the San Francisco/Silicon Valley area is male dominated and I've always had the feeling that Las Vegas is male dominated too. But I didn't expect LA to be the place with the biggest surplus of single men. The North East by contrast seems very short of single men. That's been the premise of a lot of American films and TV shows (single woman struggling to find a man in New York). I didn't realise how true it was until now!
Plan your next holiday accordingly!
