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