Excerpt:
Only a third of churchgoers actively practise their faith, as opposed to 80 per cent of Muslims, according to new research by the Office of National Statistics (above, and it can't spell "practising"). As I reported last month, the number of British Muslims has grown at an astonishing rate, from 1.65 million to 2.87 million since 2001. This figure, from the respected Pew Forum, means we must radically revise predictions that practising Muslims will outnumber practising Christians by 2035, which were based on the outdated 2001 census figure of 1.65 million (which was too low even at the time). It will happen much sooner than that.
If there are 2.87 million Muslims in Britain and 80 per cent of them practise their faith, then there are already 2.14 million practising Muslims. Admittedly, we should treat these figures with caution: 2.87 million may be an overestimate, so may 80 per cent, and in any case there's no common yardstick to to measure the practice of two such different religions. Still, I was wondering how the numbers of devout Christians compares to the number of devout Muslims.
