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 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.1 V* u. ?6 e0 P, f& W+ P7 {% c7 W

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%.\"3 X: J& N2 _7 o$ B, r! k5 V) ]

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.
