An empirical study examined the mate preferences of subscribers to a computer dating service in Israel that had a highly skewed sex ratio (646 men for 1,000 women). Despite this skewed sex ratio, they found that "On education and socioeconomic status, women on average express greater hypergamic selectivity; they prefer mates who are superior to them in these traits... while men express a desire for an analogue of hypergamy based on physical attractiveness; they desire a mate who ranks higher on the physical attractiveness scale than they themselves do."
