The Jedi census phenomenon 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. In England and Wales 390,127 people (almost 0.8 percent) stated their religion as Jedi on their 2001 Census forms, surpassing Sikhism, Judaism, and Buddhism, and making it the fourth largest reported religion in the country.
