Study was carried out by ComRes, a respected polling institution,and the sample size was 2000 adults, randomly selected to best represent the UK adult population.
I had a glance through the actual report, and the questions do not seem unnecessarily scewed to favour a religious/spiritual interpretation, although some might be considered borderline misleading.
The results are interesting. Theos have interpreted the results to put a positive spin on the underlying trends, I think. It is undoubtedly true that less and less people,year on year, attend any form of religious services apart from those culturally dictated - hatched, matched,dispatched etc., so this should not represent comforting reading for any believer of organised religion.
What comes in religions wake though? And this study fits with what others have observed; The growth of new age spiritualism, or some poorly articulated woolly minded belief in the supernatural or similar. And the big ticket issues in these "post-religious" views tend to focus around doctrines about the soul, or the presence of angels ( but, curiously, for those angel believers, they do not seem to be associated with god- they could almost be regarded as benevolent, guardian spirit alien even).
So, whilst those who do not believe in organised religion cannot necessarily be described as atheists, it certainly reflects modern trends towards a less religious outlook on life.
I would be interested to see if organised religions seriously responded to studies like these to make real changes to the hierarchies of the church and the formality and discipline required to regularly attend churches, or the extent to which they intrude into peoples private and family lives, because there is clearly an appetite amongst the general public for a belief in the "spiritual" however poorly described or articulate that belief is.
This growth of belief in personal guardian angels is fascinating t me though, partly because so many who believe this have no beleif in any of the major religions - so angels now seem to have evolved a mythology and identity completely divorced from organised religion or even god, in some instances
