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.% \% i' ~3 P3 _, f

Their means of analysing the data invokes what is known as nonlinear dynamics - a mathematical approach that has been used to explain a wide range of physical phenomena in which a number of factors play a part.

+ e! T" I3 p' Y+ o# L+ y SOne 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.5 n, O" t0 ?' W% ]# l
" x; c2 t8 Q. B5 ^$ t1 Y& O\"The idea is pretty simple,\" said Richard Wiener of the Research Corporation for Science Advancement, and the University of Arizona.

\"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.2 U2 E/ c5 C. ~8 r
# f) L9 W1 E: j3 \. L5 L\"For example in languages, there can be greater utility or status in speaking Spanish instead of [the dying language] Quechuan in Peru, and similarly there\'s some kind of status or utility in being a member of a religion or not.\"& a% \4 p4 ^9 O! w2 Q) K

N4 ?* l5 C# ]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%.\"1 U- w/ @7 i& X% Z) r! z
K2 W# z# \# G% m; P4 }5 TThe team then applied their nonlinear dynamics model, adjusting parameters for the relative social and utilitarian merits of membership of the \"non-religious\" category.

And in all the countries, the indications were that religion was headed toward extinction.% [. m/ O3 z: z/ R; a/ |8 |

\"Obviously we don\'t really believe this is the network structure of a modern society, where each person is influenced equally by all the other people in society,\" he said.

However, he told BBC News that he thought it was \"a suggestive result\".

\"Obviously much more complicated things are going on with any one individual, but maybe a lot of that averages out.\" |
