Social Construction

A social construction, social construct or social concept is an institutionalized entity or artifact in a social system 'invented' or 'constructed' by participants in a particular culture or society that exists solely because people agree to behave as if it exists, or agree to follow certain conventional rules.
Obvious social constructs include such things as games, money, school grades, titles, nationality, governments, universities, corporations and other institutions. Debatable social constructs include language, class, race, gender, religion, childhood, sexuality, morality, memory and reality.
