Tim Harford and the More or Less team try to make sense of the statistics which surround us. From BBC Radio 4

More or Less: Behind the Stats

When World War Two came to Greece, a period of terrible human suffering followed. There was a brutal battle with Italian and then Nazi forces, followed by an occupation in which thousands were executed and a terrible famine swept the nation. 

There’s an often repeated number that appears to capture the brutality of this time – that 10% of the Greek population died during the war. 

We investigate where this statistic comes from and whether it is true.

Are most Americans barely holding their head above water when it comes to personal finances?
 
That’s what various US politicians and news outlets keep suggesting. 
 
They can’t stop using a statistic about people living “paycheck to paycheck”. 
 
But what does this really mean? 

We go behind the headlines to unpick the numbers.

“Say what you like about Mussolini but he did make the trains run on time.” This phrase is the political equivalent of “every cloud has a silver lining” – but does it have any factual basis? 
 
Mussolini’s dictatorship in Italy was full of atrocities, brutal suppression and propaganda. Did it also create a more efficient railway network? 
 
We speak to Professor Ruth Ben-Ghiat about the truth of the claim and why the Mussolini regime wanted us to believe it.

Numbers of the year part 2

The claim that 79% of asylum seekers in Sweden go on holiday in their home country has been repeated regularly on social media. 
It’s used to argue that recent refugees are being disingenuous about the danger they face in the country they have fled from. 
But when you look at the survey the claim is based on, you see the stat in a very different way. 
We speak to Hjalmar Strid, who ran the survey for polling company Novus, and Tino Sanandaji from Bulletin, the online news site which published it.

What has the colour of your hair got to do with your capacity to withstand pain? 

We investigate the claim, which regularly circulates on social media, that natural redheads are 25% tougher than their brunette peers. 

Pain expert Jeff Mogil explains how it all comes down to something called MC1R.

Can redheads handle 25% more pain than brunettes?

Just before being inaugurated as US president for the second time, Donald Trump launched something called a “meme-coin”.
 
This is a bespoke cryptocurrency token featuring a picture of Donald Trump. A billion of them may eventually be created.

Newspaper headlines claimed that the Trump meme-coin had made the president billions of dollars wealthier. But it is far from clear that this is the case.

Google claim their latest quantum computer chip is able to process something in five minutes it would take a normal computer 10 septillion years to figure out.

As this is a massive amount longer than the entire history of the known universe, that seems to suggest the chip is extremely powerful. 

But when you understand what’s going on, the claim doesn’t seem quite so impressive. Dr Peter Leek, a quantum computer scientist from Oxford University, explains the key context.

Are quantum computers already super-powerful?

Babies born in the US to Black Hispanic or African American mothers are more likely to die than any other ethnic group in America. 

That is a fact. 

But the reason why this happens is unclear. In 2020 a study came out that claimed that black babies attended by white doctors after birth were twice as likely to die than white babies attended by white doctors. 

People jumped to the conclusion that the race of the doctor was leading to the different outcomes. But when you delve into the numbers, a very different picture starts to emerge.

Are black babies in the US really more likely to die under the care of white doctors?

The Royal Mail says UK stamp prices are still among the best value in Europe, despite an imminent steep price rise. Tim Harford finds out whether this is true, and compares the price of postal services around the world. Plus, he finds out how, after being invented by Indian mathematicians, modern numbers became established in the ancient Arab world and then journeyed on to Europe in what was essentially the first maths textbook ever written, "Liber Abaci". Its author was Leonardo of Pisa, better known as Fibonacci. Tim speaks to Keith Devlin, author of The Man of Numbers, to find out more. This programme was first broadcast on the BBC World Service.
