"Nearly half of teenagers in Britain are atheists, according to a new Mori poll commissioned by the British Library.
43% of 16–19 year olds say they have no faith. In those over 20 it is 20%, and that goes down to 8% in the 65+ age group. Overall, 21% of the 2,030 people questioned say they have no faith. Of those who do not follow a religion, around one third say they used to be Christian (32%), while three in five have never followed a religion in the past (58%).
Muslims are much more likely to see religion as "relevant to their life" than Christians (95% vs. 54%), with fewer than half of the people polled saying this overall (43%). The 16–19 year olds are most likely to describe religion as "not relevant" (72% vs. 54% of those aged 20+). Nearly a quarter of those polled say that religion is relevant at all times in their lives (23%); this increases to a third among those aged 65+ (33%) , but falls to 14% among 16–19 year olds . Around a quarter of all people asked say that religion is never relevant (23%)."
