As well as reading about Church coming and going, I've been reading about how people in different cultures use their computers. Forrester research has been investigating the “Groundswell” of new media. Its research analyses usage like this:
The categories are made up around what you do online. Spectators read blogs, Critics Comment on blogs, Creators originate blogs. Joiners use Facebook et al. You get the idea. An individual can be on several rungs at the same time. Proportions on each rung are vastly different in different cultures. In the US, 25% are creators — in Europe only 10%. 53% of Europeans are inactives, 41% of Americans, only 37% of South Koreans.
OK Team. This method has absolutely no tested validity at all in the field of religious participation, but let's sketch on the back of an envelope. If patterns of church involvement were similar, and for all I know they are, In the UK roughly 70% = 35m people say they are Christians. Most actives would be, er 10% = 3·5m weekly participants. Anglicans would be just under 1m bums on pews a week. Inactives would be 53% = 26·5m. They are.
Spooky, ja? Anyone care to develop this kind of approach?
