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.' E$ h4 }$ h g$ s8 n; R+ z

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.6 v# h2 m7 h! D

\"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.( \7 U& s$ \* ^4 X, U9 Q

The team then applied their nonlinear dynamics model, adjusting parameters for the relative social and utilitarian merits of membership of the \"non-religious\" category.6 U: C& Q9 n7 D0 W9 q
