Burning Man 2011, Black Rock Desert, Nevada, United States

Black Rock City is not considered a Census-designated place according to the United States Census Bureau. If it were, the year 2000 event attendance would have placed it between Carson City and Pahrump, making it the 7th largest city in the state of Nevada at the time. Since then, Paradise, Sunrise Manor, and Spring Valley (all suburbs of Las Vegas) experienced proportionally larger population growths than the rest of the state, pushing Black Rock City to the 10th largest city in Nevada according to 2004 census estimates (still between Carson City and Pahrump)
Principles
Because of the variety of goals fostered by participatory attendees, known as "Burners," Burning Man does not have a single focus. Features of the event are subject to the participants and include community, artwork, absurdity, decommodification and revelry. Participation is encouraged.
