An article by Richard Florida notes large disparities between the numbers of single men and single women in urban locations across the US. Let the conforming to already-existing gendered assumptions begin!
As you can see, if you are looking for a single man, he’s on the West Coast – if you are looking for single women, they’re on the East Coast. Of course, this says nothing about who they are, sexual orientation, and the like. Now, sure, I can go into the sociological implications of life course decision-making, job opportunities, gender differences and similarities. But really, I just want to say that if you are a straight woman in New York looking for a straight man, you’re kind of S.O.L. If you’re that same woman looking for a straight man in LA (though many more men in LA are gay than comparables elsewhere) or Dallas or Denver or Seattle, it must be you. If you are a straight man looking for a straight woman in NYC and not succeeding, you aren’t working hard enough.
