How about a similar chart listing the percentage of the population in each country who pretend daily to be a Jedi Knight or a superhero.
Such data would be of equal use in evaluating childish behaviour, I am sure
If you take into account that 5% of the UK population is muslim and the high rate of daily observance of other muslim countries they will make up the majority of the UK 6% - would like to think the low figure among anglo saxon UK is due to rational thinking and considered rejection of religion but sadly I think most just can't be arsed to get involved in anything
Well it certain shows how well those thoughts and prayers are working.
What a lovely heathen country I live in
I'd prefer to have more heathens than evangelicals any day.
