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 hypergamy and hypogamy can be considered as special cases of mésalliance.
The term hypergyny is used to describe the overall practice of women marrying up, since the men would be marrying down.

## By income

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.
The observed gender cliff in the distribution of women's share to the household income at 50% can be explained by income hypergamy preferences by both men and women, together with gender pay gap.

## By education

A study found traditional marriage practices in which men "marry down" and women "marry up" in education do not persist in countries where women have higher educational attainment.

## Differences by sex

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.
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.

## Prevalence

It is becoming less common for women to marry older men, because current socioeconomic dynamics allow women more autonomy. Hypergamy does not necessitate the man being older; rather, it requires him to have higher status. The term 'social equals' typically pertains to shared social circles rather than economic equality.
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 in each other rather than different ones.
An empirical study examined the mate preferences of subscribers to an online 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."$^{:51}$
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.

## Mathematical model

Gilles Saint-Paul (2008) proposes a mathematical model that purports to demonstrate that 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 compared to men), and thus must be compensated for this cost of marriage. At the end of his introduction, Saint-Paul states his model is consistent with statistics published by Bertrand et al (2013) but also notes that in US Bureau of Labor and Statistics (BLS) data gathered the same year "aggregate evidence is not so clear-cut."
