I grew up in a small town where every single female left at 18. I moved to a nearby university town because I read it had a six to 1 female to male ratio, and was still close enough to everyone I knew, and wasn't a huge city.
Years later, I had to move to a huge city to find the women I ended up getting engaged to. I had worked out that only 0.5% of the population met my first few requirements in a partner, so I moved to increase my chances.
So, all my major moves so far have been to go where the women are!
