Oh, come _on_, all ye faithful.
Despite the righteously indignant frothing of all our devout Atheist chums here, claiming Jedi-hood absolutely does _not_ bolster the ranks of the religious.
This is directly from the notes of the 2001 census's Religious Populations analysis, posted back in 2004:
"No religion includes people who ticked 'None' at the religion question plus those who wrote in Jedi Knight, Agnostic, Atheist and Heathen and those who ticked 'Other' but did not write in any religion."
So to be absolutely clear: atheists, agnostics, Jedis and unreadable Others are all in exactly the same category. So please, stop the damned ranting, and if people want to play Jedi Knights with the gubmint, let them be childish in peace.
The details of the census data also note that: "... many people chose to write in their own religion. _Some_ of these religions were reassigned to one of the main religions offered" (my emphasis). Also, "151,000 people belonged to religious groups which did not fall into any of the main religions. The largest of these were Spiritualists (32,000) and Pagans (31,000), followed by Jain (15,000), Wicca (7,000), Rastafarian (5,000), Bahà'ì (5,000) and Zoroastrian (4,000)."
I'm a bit depressed to see Voudessaints, Cthulhu Cultists and Discordians so poorly represented, but hey, you can't have everything.
