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

3 r, _/ Q6 a3 m) U ^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. d3 _1 ~7 W$ F$ N2 G6 K( L, e4 N

\"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.\"

The team then applied their nonlinear dynamics model, adjusting parameters for the relative social and utilitarian merits of membership of the \"non-religious\" category.& P2 {' S+ R$ n! @" h+ O

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.
