What is the term for the restriction of mate selection to people within the same group?

The term for the restriction of mate selection to people within the same group is endogamy. This practice is common in various societies and cultures where individuals are encouraged or required to choose partners from within their own social, ethnic, religious, or financial groups. Endogamy serves to preserve cultural identity and maintain social cohesion among members of the group.

In contrast, exogamy refers to the practice of seeking partners outside one’s immediate social group, which can promote wider social networks and alliances. Monogamy is a marital arrangement involving one partner at a time, while polygamy involves having multiple spouses simultaneously. These concepts highlight different aspects of relationship structures but do not specifically refer to the restriction of mate selection to one’s own group like endogamy does.
