More or Less: Behind the Stats

• How to spot a suspicious statistic

  Untruths sneak into our lives in all kinds of ways. Sometimes they’re outright lies. Blatant misinformation. But in this episode, we’re going to talk about something else - those sneaky numbers and claims that bounce around our society and that aren’t exactly false, but are leading you down the wrong path. That’s the subject of a book called May Contain Lies by Alex Edmans, a professor of finance at London Business School. Tim talks to Alex about the statistical claims that might not be wrong, but aren’t right either – and how to make sure you aren’t fooled by them yourself.Presenter: Tim Harford Producer: Tom Colls Production co-ordinator: Brenda Brown Sound mix: Andrew Garratt Editor: Richard Vadon

• Are 4% of young women in the UK on OnlyFans?

  Tim Harford investigates some of the numbers in the news, and in life. This week:We debunk a false claim that the hotel bill for immigrants is the size of the tax bill for Manchester.An article in the Spectator claimed that 4% of women aged between 18 and 34 in the UK are OnlyFans creators. We track down the source and discover that it is not very good.Do people in Scotland use much more water than people in Yorkshire? If so, why?And we examine a popular claim that today’s working mothers spend more time with their children than your stereotypical 1950s housewife did.Make sure you get in touch if you’ve seen a number you think Tim and the team should take a look at.

• Could you be hit by a falling satellite?

  The number of satellites orbiting our planet has been rapidly increasing in recent years. But what are the risks when they start falling back down to earth?The European Space agency estimate that by 2030 there will be 100,000 satellites in orbit. We look at whether that estimate is realistic and what it means for those of us living on the ground below, with the help of Jonathan McDowell and Fionagh Thomson.

• How do you make something 10-times more lethal?

  What does the government mean when it commits to developing a “10-times more lethal” army? Why was the much-missed Sycamore Gap tree said to be worth a strikingly exact £622,191? Are there really twice as many people teaching Yoga as there are in the fishing industry? Is the number of workers per pensioner really falling from 4 to 3 to 2? And what did Donald Trump mean when he said the price of eggs had fallen by 400%?Tim Harford investigates some of the numbers in the news. If you want us to look at a number you think looks a bit suspicious, email the team - [email protected] note an earlier edition of the programme incorrectly stated that the new EU-UK fishing agreement would last 4 years. The agreement length is 12 years. More or Less is produced in partnership with the Open University.

• Is the world’s population being miscounted?

  Exactly how many people live on our planet is one of those difficult-to-answer questions. The UN estimates is 8.2 billion, but that’s largely based on census data, which is certainly not a perfect measure. So when a recent study from Finland found that rural populations around the world had been underestimated by 50 to over 80%, the media got quite excited. This would be a big error - a 50% underestimate would mean the actual number of people in an area is double the number they thought there were. One newspaper in Spain - El Mundo - did its own sums and said this meant there were potentially 2 billion more people in the world than we currently think there are. But is it what the researchers in Finland actually meant? “Absolutely not,” says Josias Lang-Ritter, a researcher from University in Finland and a co-author of the study.Tim Harford speaks to Josias to figure out the right way of understanding the study.Presenter: Tim Harford Producer: Caroline Bayley Series producer: Tom Colls Production co-ordinator: Brenda Brown Sound mix: Nigel Appleton Editor: Richard Vadon
