Polls like this are always interesting to me because there's so much that can go into a person's answer to any of these questions.

For instance, per the article most of these "Nones" still believe in God or Gods but don't subscribe to a particular religion. They're definitely not atheists as you might expect from the label.

On the flip side, I know some people who would probably answer this poll as Catholic even though they don't attend church, don't believe that any miracles in the bible literally happened etc.

To add to this even more, there is the lumper/splitter problem of which groups we count as one. As others have pointed out, Christians would outnumber the Nones if they were all put in the same group. But how we decide to slice things up can affect how the results look.
