Where is Jedi in your poll?
In England and Wales 390,127 people (almost 0.8%) 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. In the 2001 Census, 2.6% of the population of Brighton claimed to be Jedi. The percentages of religious affiliations were:
Christian: 70%
No religion: 16%
Chose not to respond: 7.8%
Muslim: 3.1%
Hindu: 2.1%
Jedi: 0.7%
I'm sure it's a few positions above Scientology.
