Of course, it wasn’t as strong as it was under a Labour government, but it’s a little hard to argue with the 2011 British census numbers:
Today’s Census figures show that 176,632 people in England and Wales identify themselves as Jedi Knights, making it the most popular faith in the “Other Religions” category on the Census and the seventh most popular faith overall.
Although the number of Jedis has dropped by more than 50 per cent over the previous 10 years, they are still the most selected “alternative” faith on the Census, and constitute 0.31% of all people’s stated religious affiliation in England and Wales.
The number of people specifically identifying as Atheists was 29,267, while over 13.8 million refused to identify with a faith at all, ticking the “No religion” box on the census form.
I’d have to double-check, but I think this was part of their “voluntary” form, since 4 million people didn’t bother with the “religion” category.
