Europe’s march towards a post-Christian society has been starkly illustrated by research showing a majority of young people in a dozen countries do not follow a religion.

The survey of 16- to 29-year-olds found the Czech Republic is the least religious country in Europe, with 91% of that age group saying they have no religious affiliation. Between 70% and 80% of young adults in Estonia, Sweden and the Netherlands also categorise themselves as non-religious.

The most religious country is Poland, where 17% of young adults define themselves as non-religious, followed by Lithuania with 25%.
