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

The study found a steady rise in those claiming no religious affiliation.

The result, reported at the American Physical Society meeting in Dallas, US, indicates that religion will all but die out altogether in those countries.

* Q8 N; J3 z* p! p( P5 FThe 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.

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.

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

The team then applied their nonlinear dynamics model, adjusting parameters for the relative social and utilitarian merits of membership of the \"non-religious\" category.4 n% y7 e0 H, k

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.
