Debating the Global Church Count: Evidence and Estimates

Tim Harford investigates some of the numbers in the news and in life. This week:

Is the secret to halving obesity rates really just a matter of cutting back on one fizzy drink a day?

How many new babies in the City of London have a foreign-born parent? And since fewer than one baby a week is actually born in the City of London, how much should we care?

Electricity in the UK is more expensive than almost anywhere else. Why? And is it anything to do with wind turbines?

And we help out rival Radio 4 programme Start the Week with a claim about churches.

If you’ve seen a number in the news you think we should take a look at, email the team: moreorless@bbc.co.uk
