The Jedi census is a grassroots movement
that was created in 2001 for citizens of a number of
English-speaking countries to record their religion as "Jedi" or
"Jedi Knight" on the national census. The campaign was loosely
organized by circulating e-mails claiming that if enough people
entered "Jedi", it would be recognized as an official religion by
the government. The emails also implored people to report their
religion as "Jedi", "Because you love Star Wars" or "just to annoy
people".
If Jedi had been counted as an answer in the 2001 census it
would have been the second largest religion in New Zealand.
