The traditional Hopi are organized into clans. When a man marries he becomes a member of his wife's clan. The Bear Clan is the most prominent clan. Tom Banyanca, now deceased, a member of the Bear Clan, was designated to transmit the Hopi Prophecy to the outside world.
The Hopi, more than most Native American peoples, have retained and continue to practice their traditional ceremonial culture. However, like other tribes, they are severely impacted by the ambient American culture. Traditionally the Hopi were highly skilled subsistance farmers. With the installation of electricity and the necessity of having a motor vehicle and the other things which can be purchased, the Hopi have been moving into a cash economy with many people seeking and holding outside jobs as well as earning money from traditional crafts.
The Hopi have been impacted by very active missionary work by a number of religions and also by consumerism and alcoholism. Nevertheless there is a traditionalist core which adheres to traditional ways.
