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

On Friday 1st August the US Bureau of Labor Statistics put out their job report data for August. It included revisions to their estimates for the jobs created in May and June which stated there were 258,000 fewer jobs than they had previously estimated.
This news was not received well by the White House. President Trump fired the head of the bureau, Erika McEntarfer, calling the numbers ‘phony, rigged, a scam’ and spreading conspiracy theories that McEntarfer had fudged the data. 
We speak to economist Michael Strain from the American Enterprise Institute, to understand why the revisions happened and the potential consequences of throwing doubt on one of the US’s most important statistical agencies.

Why it matters that Trump fired data chief

In June 2022 the United States Supreme Court passed what became known as ‘the Dobbs decision’. In doing so they overturned the long standing constitutional right for women to access abortion in the US. 
 
Since then a number of states have banned abortion completely with many others having highly prohibitive rules. You’d expect the numbers of abortions to go down. They haven’t. 
 
How is it possible that more people are accessing abortions in a post Dobbs society and why is it not true that states which have total bans have zero abortions per year?

Are abortion numbers rising in the US?

We’re living through boom-times for Artificial Intelligence, with more and more of us using AI assistants like ChatGPT, DeepSeek, Grok and Copilot to do basic research and writing tasks. 

But what is the environmental impact of these technologies? 

Many listeners have got in touch with More or Less to ask us to investigate various claims about the energy and water use of AI.

One claim in particular has caught your attention - the idea that the equivalent of a small bottle of drinking water is consumed by computer processors every time you ask an AI a question, or get it to write a simple email. 

So, where does that claim come from, and is it true?

Does a single AI query use a bottle of water?

In the midst of the television coverage of Soccer Aid, a celebrity soccer match organised by Unicef, the audience was told that “one in six children around the world are currently living through war”. 

Listener Isla got in touch with More or Less to ask whether the claim was correct, so we tracked down the source to an organisation called the Peace Research Institute Oslo.

Research director Siri Aas Rustad tells us how they worked out a figure for the number of children living near to a “conflict” and the big differences between that and something most people would think of as “war”.

Are one in six children living through war?

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.

Can drinking one less bottle of coke a day halve obesity?

Manchester United are terrible, even according to their own manager. Last season saw their worst ever performance in Premier League history.

But at the same time, according to Forbes magazine, they’re still the second most valuable football club in the world. 

How is that possible?

Tim talks to Kieran Maguire, a football finance expert and the author of The Price of Football, to find out the secret of Manchester United’s financial success.

How does economics help us understand conflicts through history? 

That’s the question that economist and journalist Duncan Weldon tries to answer in his new book, Blood and Treasure. 

Tim talks to Duncan about the economic perspective on Viking raiders, Spanish conquest and the Vietnam war.

The economics of war: Vikings, Conquistadors and Vietnam

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

Is church-going making a comeback in the UK?

Is it true that every day, 1000 people begin claiming personal independence payments, or PIP?

When the government talks about how it “returns” illegal immigrants, what does it mean?

Can a new telescope really see golf balls on the moon?

Is the UK seeing a Christian revival?

It’s been over three years since Russia’s full-scale invasion of Ukraine and the human toll is growing on both sides.

Recently, politicians and journalists have declared a grim milestone, one million Russian casualties.

But is this number accurate? 

Tim talks to Seth Jones, from the Center for Strategic and International Studies, and Olga Ivshina, from the BBC Russian service, to investigate this statistic.

Has Russia suffered a million casualties in the Ukraine war?

Tim Harford looks at some of the numbers in the news and in life. In this episode:

Why is the data on the ethnicity of grooming gangs of such poor quality?

Iran has apparently enriched uranium to 60%, but what does that number mean?

Adam Curtis’s latest series, Shifty, includes claims about Margaret Thatcher’s rise to power. We ask Sir John Curtice, polling king of election night, if they’re accurate.

And we ask an economist to explain why being pillaged by a Viking might be more lucrative than you’d imagine.

How many images of Queen Elizabeth II have ever been created? And is Facebook really worth more than twice as much as every company on the Nigerian Stock Exchange?

Counting images of The Queen. (WS)
