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.+ {! Y7 c" Y! q1 g; r/ [

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

\"The idea is pretty simple,\" said Richard Wiener of the Research Corporation for Science Advancement, and the University of Arizona.

\"It posits that social groups that have more members are going to be more attractive to join, and it posits that social groups have a social status or utility.

\"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.\"

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.

\"Obviously we don\'t really believe this is the network structure of a modern society, where each person is influenced equally by all the other people in society,\" he said./ p- @- M5 v" V4 N0 Y* u

\"Obviously much more complicated things are going on with any one individual, but maybe a lot of that averages out.\" |
