The result, reported at the American Physical Society meeting in Dallas, US, indicates that religion will all but die out altogether in those countries.* z$ g; }+ F4 r% W$ ?

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.

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.0 B/ y7 w! f! T9 A

One 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.7 R) Z6 G: k8 {$ R- w, k

At its heart is the competition between speakers of different languages, and the \"utility\" of speaking one instead of another.
