"A study using census data from nine countries shows that religion there is set for extinction, say researchers.
The study found a steady rise in those claiming no religious affiliation.
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.
"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.
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%."
And in all the countries, the indications were that religion was headed toward extinction."
