The Singles Map

Via Pharyngula" comes this interesing map of the number of single males and females by city. Unfortunately it is a raw figure, so the 40,000 extra males in Los Angeles really doesn't mean that much. Still, it is interesting to look at the clear pattern of male dominance of the west and females in the east. I've seen several hypotheses, the most popular seeming to be correlation with age, but I'm unconvinced.
