Who typically performs ballroom dances?

Ballroom dancing is a type of social dancing, originally practiced in Europe and the United States, that is performed by couples and follows prescribed steps. The tradition was historically distinguished from folk or country dance by its association with the elite social classes and with invitational dance events. In the 21st century, however, ballroom dance is present in many parts of the world and has practitioners in virtually all segments of society. It is performed in various contexts, including invitational and public dance events, professional dance exhibitions, and formal competitions.
