Organized religion is religion, at least the major ones, I know you're trying to say that it doesn't state "belief in god" is extinct and it doesn't. No, "unaffiliated" doesn't necessarily mean agnostic/atheist, but it usually does, it's not what you're trying to say it is.....not choosing a sect of the religion, it's no affiliation to any religion, not church within the religion.

But no you're wrong, that's not the case. It points out that the question wasn't asked if they identify as agnostic/atheist, but the "no affiliation to any religion" usually what that means(though it doesn't always, can't say it does) and no I'm not making that up, nor is that just my interpretation. I've read a ton of these surveys, esp. ones here in the US which say the same thing btw, the question isn't what you said it is at all - it's no religious affiliation. You may not attend church, but you affiliate yourself with the Christian religion. And I've read it's also asked in that way for several reasons but one main one...There's several different terms people can be as a non-believer or how they identify themselves from agnostic, atheist, humanist, secularist etc. They don't list every single one like they don't list baptist, Methodist etc. etc either...it's all in one question.
