Mate selection is a complex process influenced by love, attraction, and social norms, which often operate subtly in shaping who individuals choose as partners. Sociologists categorize mate selection into two main types: endogamy and exogamy. Endogamy refers to marrying within one's social group or category, such as a middle-class person marrying another middle-class individual. In contrast, exogamy involves marrying outside one's social category, like a working-class person marrying someone from the upper class. Endogamy tends to be more prevalent in closed social systems where social hierarchy limits potential partners, whereas exogamy is more feasible in open social systems with greater social mobility.
Regardless of whether endogamy or exogamy is practiced, homogamy is commonly observed. Homogamy means marrying someone similar to oneself in key aspects such as social class, race, ethnicity, or educational level. This tendency arises because shared characteristics often foster compatibility and mutual understanding in relationships.
Marriage structures also vary, primarily between monogamy and polygamy. Monogamy, the union between two individuals, is the most widespread form globally and is especially common in high-income, industrialized societies. Polygamy, on the other hand, involves marriage to more than one person simultaneously and can be divided into two types: polygyny and polyandry. Polygyny is a marriage where one man has multiple wives, while polyandry is a marriage where one woman has multiple husbands. A useful way to remember the difference is by associating "andry" in polyandry with "androgen," a hormone more prevalent in males, indicating multiple men in the marriage.
Understanding these concepts of mate selection and marriage structures highlights how social norms and cultural contexts shape intimate relationships, reflecting broader societal organization and values.
