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

The team\'s mathematical model attempts to account for the interplay between the number of religious respondents and the social motives behind being one.

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

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.

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%.\"
