I think quite a few people tick Christian because the UK is culturally Christian. They may not go to church every Sunday, but they will expect to marry in a church or Christen their children there. I think someone can belong culturally to a religion without being a follower of the faith. If that makes sense...

Maybe people who tick no religion, agnostic, athiest etc. should be asked if they would like to work over religious holidays like Christmas and Easter. If that were the case I think we'd suddenly find many more cultural Christians.
