Losing your religion can be good for your wealth, claims a new study carried out by the universities of Bristol and Tennessee. It argues that as nations become more secular, they tend to become richer.

Researchers examined the gross domestic product of 109 countries, alongside the importance of religion in the societies studied. They found that an increase in secularisation correlated with an average increase of £800 per person over a period of 10 years, and this increased further over subsequent decades.
