Hypergamy (colloquially referred to as  marrying up ) is a term used in social science for the act or practice of marrying someone who is wealthier or of higher caste or social status than oneself.
Today most people marry their approximate social equals, and in much of the world hypergamy is felt to be in slow decline: for example, it is becoming less common for women to marry older men. However, even in relatively gender-equal societies it is accepted that young women will often partner with powerful older men.
