From Tim Harford's "The Logic of Life"
As ever, economists aren’t satisfied with folk wisdom. And fortunately, there is a data source to settle all (well, almost all) controversy on the matter: internet dating success rates. Economists have been studying Internet dating just as assiduously as they study speed dating, and have found that men attract a lot of replies if their Internet dating ads claim a high income. The situation is reversed for women: if a woman claims a high income in an Internet dating ad, she will receive fewer replies than if she had claimed a modest income. It is official: rich men are a turn-on and rich women are a turn-off.
Perhaps you don’t think Internet dating responses are really a window on to the soul. You maybe right, but there are other sources of evidence. If, as George Gershwin, evolutionary biologists and Internet daters suggest, women are particularly interested in netting themselves a rich man, then presumably we should find lots of women in places where there are lots of rich men: that is, in the cities. Since men aren’t as interested in marrying someone with high earning power, the good marriage prospects in the cities are less of an attraction to men than women. As rents rise, it will be the unskilled men who give up and move to the country before the unskilled women do – or who never bother to move to the cities in the first place.
The economist behind this idea is Lena Edlund of Columbia University. She explained the implications to me. First, men would always be in shorter supply in cities than in the countryside. In forty-four out of forty-seven countries studied by Edlund, they are. Within the US, you find the same pattern in the big cities. In Washington, DC, women outnumber men nine to eight. IN NYC, there are 860K men between ages 20 and 24, there are 910K women. There are more men, though, in rural states: Alaska, Utah and Colorado.
