Hypergamy

Hypergamy (colloquially referred to as "dating up" or "marrying up") is a term used in social science for the act or practice of a person dating or marrying a spouse of higher social status or sexual capital than themselves.
The antonym "hypogamy" refers to the inverse: marrying a person of lower social class or status (colloquially "marrying down"). Both terms were invented in the Indian subcontinent in the 19th century while translating classical Hindu law books, which used the Sanskrit terms anuloma and pratiloma, respectively, for the two concepts.
The term hypergyny is used to describe the overall practice of women marrying up, since the men would be marrying down.
Research
One study found that women are more selective in their choice of marriage partners than are men.
A study done by the University of Minnesota in 2017 found that females generally prefer dominant males as mates. Research conducted throughout the world strongly supports the position that women prefer marriage with partners who are culturally successful or have high potential to become culturally successful. The most extensive of these studies included 10,000 people in 37 cultures across six continents and five islands. Women rated "good financial prospect" higher than men did in all cultures. In 29 samples, the "ambition and industriousness" of a prospective mate were more important for women than for men. Meta-analysis of research published from 1965 to 1986 revealed the same sex difference (Feingold, 1992). Across studies, 3 out of 4 women rated socioeconomic status as more important in a prospective marriage partner than did the average man.
Gilles Saint-Paul (2008) argued that, based on mathematical models, human female hypergamy occurs because women have greater lost mating opportunity costs from monogamous mating (given their slower reproductive rate and limited window of fertility), and thus must be compensated for this cost of marriage. Marriage reduces the overall genetic quality of her offspring by precluding the possibility of impregnation by a genetically higher quality male, albeit without his parental investment. However, this reduction may be compensated by greater levels of parental investment by her genetically lower quality husband.
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."
One study did not find a statistical difference in the number of women or men "marrying-up" in a sample of 1,109 first-time married couples in the United States.
Another study found traditional marriage practices in which men “marry down” in education do not persist for long once women have the educational advantage.
Additional studies of mate selection in dozens of countries around the world have found men and women report prioritizing different traits when it comes to choosing a mate, with both groups favoring attractive partners in general, but men tending to prefer women who are young while women tend to prefer men who are rich, well-educated, and ambitious. They argue that as societies shift towards becoming more gender-equal, women's mate selection preferences shift as well. Some research supports that theory, including a 2012 analysis of a survey of 8,953 people in 37 countries, which found that the more gender-equal a country, the likelier male and female respondents were to report seeking the same qualities as each other rather than different ones.
In a 2016 paper that explored the income difference between couples in 1980 and 2012, researcher Yue Qian noted that the tendency for women to marry men with higher incomes than themselves still persists in the modern era.
Prevalence
It is becoming less common for women to marry older men (Hypergamy does not require the man to be older, only of higher status, and social equals usually refers to social circles rather than economic equality.).
