Here in New Zealand it seems to me that there is a substantial portion of the population that just doesn't really care about religious issues at all. Perhaps it's just the people who I associate with, but I suspect it is somewhat representative of the population at large.
Out of the approximately 100-300 people I interact with socially on a regular-infrequent basis the topic of religion only comes up in conversations with an extreme minority of them (less than 10%). Out of those few, less than half of them are religious (and half of those that are religious are my own family members). A large number of my friends that I grew up going to church with have either stopped going altogether, or still go, but no longer believe. Approximately (very rough guess) 10-30% of those from the aforementioned social group nominally belong to some religion. For example it might list 'Christian' on their facebook info, but that's about the extent of their outwards religiosity. As far as I can tell, the remainder of the group either is nominally irreligious, believes in a 'higher power' or just don't seem to give a damn.
Just to clarify, if any of you are reading this post, I'm not trying to criticise your beliefs or lack thereof, just pointing out what I think is an interesting piece of sociological data.
The reason I'm so fascinated in these issues is because I used to be so religious, and I find the phenomena of religious belief intriguing. For those on whom religion has had a negligible effect it may all seem like hocus pocus and make-believe, or just something that's a part of life that doesn't need to be questioned. No real over-arching point to this, but hopefully it has given you something to think about.
