More or Less

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.

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.

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.

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.

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 Producer: Nathan Gower Editor: Richard Vadon Programme Coordinator: Brenda Brown Sound Engineer: James Beard

Portugal has a divorce rate of 94% and India just 1%, according to a social media post about divorce in 33 countries that has gone viral. But how are these figures calculated and what do they really tell us about the quality and endurance of marriage? We investigate with guests Marina Adshade, assistant professor at the Vancouver School of Economics and Dr Cheng-Tong Lir Wang of the Institute for the Future in San Francisco.Presenter: Ben Carter Producers: Octavia Woodward and Jon Bithrey Editor: Richard Vadon Production Co-ordinator: Brenda Brown Sound Engineer: Neil Churchill

The average life expectancy of Americans is shrinking at an alarming rate. Between 2019 and 2021, a staggering 2.7 years has been shaved off, leaving the revised figure at 76.1 years - the lowest it’s been in more than two decades. It also sees the U.S. rank 46th in the global life expectancy charts, behind Estonia and just a nose ahead of Panama. Paul Connolly is joined by John Burn Murdoch, Mary Pat Campbell and Dr Nick Mark to discuss why, on average, citizens of the world’s richest country are dying so young.

Consisting of 2 kilograms of gold and 444 gemstones, the iconic St Edward’s Crown will play a central role in the coronation of King Charles III, as it has for many of his predecessors. There has been much speculation as to what the value of the centrepiece of the Crown Jewels really is. Charlotte McDonald talks to Dr Anna Keay, historian and author of The Crown Jewels - the Official History, and Alan Hart, CEO of the Gemmological Association of Great Britain. Together they break down what we know about the crown’s cost to make in the 17th century and what it might be worth today.

The leaking of US intelligence documents and the arrest of a 21 year old airman who authorities believe to be responsible has caused a media and diplomatic storm. We look at how the leaks were reported by primetime Fox News host Tucker Carlson, who said seven Ukrainian troops are dying for every one Russian, contrary to most estimates. And we examine an advert Fox News took out claiming to be the American TV network most trusted for news. With guests Aric Toler from investigative journalism site Bellingcat, data journalist and author G. Elliott Morris and BBC correspondent Olga Ivshina.
