More than 70,000 Australians declared themselves members of the Jedi in the 2001 census, thanks to a fad fueled by e-mail. So did 53,000 New Zealanders and 20,000 Canadians. In England and Wales, 390,000 people gave their religion as Jedi, making it the country’s fourth largest reported religion, behind Christianity, Islam, and Hinduism.
Ironically, the stunt led many otherwise apathetic people to take the census, so it may actually have improved its quality.
