Earlier this year YouGov@Cambridge did a census of British life and attitudes, using a representative sample of adult Britons. Some of the questions were on religion, and British Religion in Numbers (BRIN) has published this summary of the results: YouGov@Cambridge on Religion. It starts:
40% of adults professed no religion, 55% were Christian and 5% of other faiths – age made a major difference, with only 38% of the 18-34s being Christian and 53% having no religion, whereas for the over-55s the figures were 70% and 26% respectively.
BRIN’s conclusion is:
All in all, these data point to a society in which religion is increasingly in retreat and nominal. With the principal exception of the older age groups, many of those who claim some religious allegiance fail to underpin it by a belief in God or to translate it into regular prayer or attendance at a place of worship. People in general are more inclined to see the negative than the positive aspects of religion, and they certainly want to keep it well out of the political arena.
