A study using census data from nine countries shows that religion there is set for extinction, say researchers.

The team\'s mathematical model attempts to account for the interplay between the number of religious respondents and the social motives behind being one.5 Y# o' g& ?( I8 g

Dr Wiener continued: \"In a large number of modern secular democracies, there\'s been a trend that folk are identifying themselves as non-affiliated with religion; in the Netherlands the number was 40%, and the highest we saw was in the Czech Republic, where the number was 60%.\"2 Y0 J( i1 p' C3 j% ?2 h

The team then applied their nonlinear dynamics model, adjusting parameters for the relative social and utilitarian merits of membership of the \"non-religious\" category.
