We did ask “what is your religion, if any” but it was a free-form text box, and about 1/3 left it blank which could mean no religion, or could mean they’d prefer not to say. So I could slice it a bunch of ways but don’t think given the ambiguity there’s a huge amount of useful insight you could reliably draw from it.
We learnt a heap of things from doing that survey - there are things we didn’t ask that I wish we had (like disability!), and questions we could have asked better. The next post will be way more interesting
