Mortgages, birth rates and does space contribute 18% to UK GDP?
Mortgage rates have risen to 6%. But are things as bad as when rates were much higher in the 1970s and 80s? We look at just how much pain today's rises mean. Also will there be just 6 grandchildren for every 100 South Koreans today? And we look into a claim that the space industry supports 18% of the UK's economy.Presenter: Tim Harford

Is breastfeeding the key to exam success?
A new study by researchers at Oxford University has linked better exam results at school with being breastfed as a baby. But how much faith can we put in the findings? Tim Harford speaks to Emily Oster, professor of economics at Brown University in the US and the author of three books about pregnancy and parenting.

Electric vehicles, 600 million bottles and does oral sex cause cancer?
There's been a lot of coverage about the risks electric cars may pose to infrastructure like bridges and car parks. We look at how much heavier EVs are. Plus we look at a new study that suggests a link between breastfeeding and improved grades at GCSE level. Also is throat cancer now primarily caused by a sexually transmitted disease - and are 600 million bottles going to litter Scotland because of disagreements with the UK government over the new Deposit Return Scheme?

Lib Dem ambulance claims, affordable rent and goat meat
The Liberal Democrats say 120 people a day in England died last year whilst waiting for an ambulance. We investigate whether the claim stands up to scrutiny. Also Rishi Sunak's pandemic-era scheme Eat Out To Help Out is back in the spotlight. How much did it really contribute to a second wave of infections? We look at a claim that no single woman in England on an average salary can afford to rent a home of her own. And Jonathan Agnew said on Test Match Special that goat is the most eaten meat in the world. Is he right?Presenter: Tim Harford

A short history of data
We live in a world where data is everywhere – informing if not governing our lives. But this wealth of data didn’t just turn up overnight. Tim Harford talks to academics Chris Wiggins and Matthew Jones, whose new book How Data Happened aims to explain how the world we know today has been shaped by not just technological developments but battles around how emerging sources of data should be utilised.

Food prices, net migration and beef about beef
Does Britain really have the most affordable food in Europe? That's a recent claim of the President of the National Farmers' Union. We ask if it's true and look in detail at what is driving rising food prices in the UK. We also try and make sense of the latest net migration figures, ask if dating apps are making Gen Z more single and explain why a correction to a correction on Radio 4's Farming Today wasn't quite right.

Are young people more single than ever before?
What’s the definition of being single – and how easy is it to measure? There’s a perception that young people today are more single – in a relationship sense - than ever, and dating apps are to blame. But how true is that? Ellie House investigates, with the help of Marina Adshade of the Vancouver School of Economics.

NHS waiting lists, Voter ID and measuring divorce
The government has trumpeted a big fall in those waiting over 18 months for hospital treatment in England. But total numbers on waiting lists have hit a new high. Also we look at how much impact the introduction of Voter ID had on turnout in May's English local elections. We ask whether Portugal really has a divorce rate of 94%. And we remember mathematician Dr Vicky Neale of Oxford University, who has died at the age of 39.

Detecting Bad Science with Data
For more than a decade there’ve been longstanding concerns about the credibility and reliability of science research. This “bad science” has often stemmed from poor data practice or worse. But statistics can also help us identify and understand some of what’s going wrong, whether that’s selective data-slicing or outright fabrication.Tim Harford talks to writer and broadcaster Michael Blastland about his new BBC radio documentary ‘The Truth Police’, which hears from the outsiders who are calling out fraud, malpractice and incompetence in science.Presenter: Tim Harford
