The result, reported at the American Physical Society meeting in Dallas, US, indicates that religion will all but die out altogether in those countries.0 z8 O5 P2 `4 L2 ^
& {% Q$ `' f5 r) SThe 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.1 A0 L' G' i6 A9 m; F/ {
( t# o) R. _% j8 ?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.6 k- a D5 O! ]- \& H

\"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.\". I2 I: E! w+ l6 d, {4 b' v# O5 ~

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.8 O) G1 d2 H$ [4 X( Y5 Q

And in all the countries, the indications were that religion was headed toward extinction.
