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

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

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.

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.
