More or Less

How do different countries compare, in terms of the amount of time that workers take as sick leave?

Loyal listener Dave got in touch to ask us to look at a surprising statistic he saw in the news – that the average German takes 19.5 days of sick leave per year.

“This is extremely hard to believe,” he wrote.

We track down the – highly reliable – source of the claim, and look at the differences between countries when it comes to taking time of work with illness.

To guide us through it all is Lukas Lehner - assistant professor at the University of Edinburgh.

Sometimes world events of massive practical significance lead our minds towards some lovely impractical thoughts. So it was for loyal listener, Nigel.

Pondering the conflict in Iran, and the maritime ownership of the Straits of Hormuz that has become its focus, his mind wandered to an altogether bigger and - honestly - far less important question.

“How much of the world surface actually doesn't belong to anyone?” he wondered.

To try and answer Nigel’s question, we enlisted the help of Mark Cooper-Jones, one half of YouTube duo Map Men.

As part of their mandate to stop 'waste, fraud and abuse' in federal government spending, DOGE, the department of Government Efficiency, made large cuts to the amount of money the US spent on foreign aid.

The task force, headed by Elon Musk, effectively dismantled the US's largest foreign aid agency, USAID - cancelling many of its programmes and absorbing the remainder into the State Department.

This has caused controversy in some circles, with researchers estimating that the cuts could result in the loss of 14 million lives by 2030. Musk strenuously denies this, stating that cuts made by DOGE has resulted in 'zero' deaths.

But who is right, and what are the problems with these sorts of estimates? We speak to Dr Hannah Ritchie to find out more.

Earlier this year, South African-born tech tycoon Elon Musk briefly became the world’s first dollar trillionaire.

This prompted loyal listener Stephen to email the More or Less team, to ask us to investigate something his daughter had been pondering: For all Musk’s vast wealth, what does it equate to as a proportion of all the wealth in the world?

How much of all the money does Elon Musk have?

We set about trying to figure this out, with the help of Robin Wigglesworth, author of A Fabulous Debt and journalist at the Financial Times.

If you had a choice between instantly receiving £50,000 or a 50% chance to win £1m, which would you pick?

When YouGov asked exactly that question to people in the UK, 73% said they would take the £50,000, while 21% opted for the 50/50 chance of winning £1m.

As you may or may not have imagined, this finding provoked outrage on Twitter, with people saying the UK appeared incredibly risk averse. “This is what’s wrong with Britain,” wrote celebrity polling analyst and More or Less interviewee Nate Silver.

But is the result surprising, when you know a bit more about how people make decisions like this? BBC economics editor Faisal Islam explains why he thinks not.

What is the error in the calculation Donald Trump used to work out his new tariffs?

What happened when the government ordered a recount of bobbies on the beat?

When is a tax freeze not a tax freeze?

And do redheads really have a 25% higher tolerance to pain?

Tim Harford investigates some of the numbers in the news.

The crime rate in London has been cropping up regularly on social media and in political discussions - US president Donald Trump has claimed that crime in the city is ‘through the roof’.

But what does the data tell us?

Professor Matt Ashby, from University College London’s Centre for Global City Policing, has put together statistics that allow you to start to compare crime rates between cities around the world.

As the 2026 World Cup approaches its end, what is the biggest factor in who wins? Is it extraordinary moments of attacking magic? Gritty defensive organisation? Or is it all just a question of luck and random chance?

Recently a post did the rounds on Twitter, claiming that people who play tennis live on average 9.7 years longer than people who play other sports.

The figure comes from a recent analysis of people's exercise habits in Denmark.

But not everyone on Twitter was convinced. Tennis is a sport that in many countries is expensive to play and so attracts wealthier players. Couldn't it be the players' socio-economic status driving the trend?

We speak to medical statistician Adam Jacobs, to understand what the study in question can, and cannot, say for certain.

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

(00:32) A government minister has informed the nation that average teacher pay in England is around £54,000. Radio 4 listeners are howling at the radio in disbelief. Surely someone from the IFS would be able to explain all this? We interview someone from the IFS to explain all this.

(06:32) A headline in the Independent suggests that Russian soldiers survive an average of 20 minutes when they get to the front line, citing a historian, citing Russian bloggers. Is the number a good one? We take a peek into the murky information ecosystem that surrounds the war in Ukraine.

(15:00) A loyal listener has resent a burning question that - mortifyingly - he first asked us nearly three years ago: why is air travel cheaper than rail travel? We push our guilt deep, deep down then make it worse by challenging the premise of the question.

(21:18) Is every shuffle of a deck of cards an unprecedented event in the history of the universe? It’s a bold claim, but maths YouTuber and comedian Matt Parker has done his homework. We invite him into the studio to make his case - and show off his shuffling skills.
