The study found a steady rise in those claiming no religious affiliation. N7 B' `. T: y5 \

The team\'s mathematical model attempts to account for the interplay between the number of religious respondents and the social motives behind being one.( T7 R, _2 n3 I) l3 D9 c, m2 G. o9 {
& S5 G& F8 W( wThe result, reported at the American Physical Society meeting in Dallas, US, indicates that religion will all but die out altogether in those countries.

The team took census data stretching back as far as a century from countries in which the census queried religious affiliation: Australia, Austria, Canada, the Czech Republic, Finland, Ireland, the Netherlands, New Zealand and Switzerland.

4 K7 `* {6 H, S( UOne of the team, Daniel Abrams of Northwestern University, put forth a similar model in 2003 to put a numerical basis behind the decline of lesser-spoken world languages.

At its heart is the competition between speakers of different languages, and the \"utility\" of speaking one instead of another.3 X* r1 r, r7 K4 m* ~4 Z. P/ A: k8 K

\"It posits that social groups that have more members are going to be more attractive to join, and it posits that social groups have a social status or utility.

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%.\".

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

They found, in a study published online, that those parameters were similar across all the countries studied, suggesting that similar behaviour drives the mathematics in all of them.

However, Dr Wiener told the conference that the team was working to update the model with a \"network structure\" more representative of the one at work in the world.
