Does it take 10,000 litres of water to make a pair of jeans?

Does it take 10,000 litres of water to make a pair of jeans?

Various claims have been made about how much water is used in the production of a pair of jeans, that cornerstone of casual clothing. With growing worries over the environmental impact of denim production, More or Less decided to investigate - with the help of journalist and researcher Elizabeth L. Cline who has written extensively on sustainability and the fashion industry. This programme was first broadcast in July 2022. Presenter: Tim Harford Producers: Lizzy McNeill, Jon Bithrey Programme Coordinator: Brenda Brown Sound engineer: Neil Churchill Editor: Richard Vadon (A worker sews blue jeans in a textile company in Xintang, China, dubbed the 'denim jeans capital of the world'.

Immigration: A More or Less Special Programme

Immigration: A More or Less Special Programme

More than 1.2 million people came into the country to stay for more than 12 months in 2022. As only 560,000 left the country, this means net migration is at an all-time high. Both the Prime Minister and Home Secretary have said the number of people coming needs to come down. But who counts as an immigrant? How are the figures worked out? Charlotte McDonald will be finding out what the numbers tell us about who is coming to the UK and why. Plus - what about the people who left in 2022?

Will there be just 6 grandchildren for every 100 South Koreans?

Will there be just 6 grandchildren for every 100 South Koreans?

An article on the UK’s Telegraph newspaper website claimed that there would be just 6 grandchildren for every 100 South Koreans today. We ask whether that figure is correct and look at why South Korea’s birth rate has fallen to one of the lowest in the world, with the help of author and mathematician Rob Eastaway and journalist and author Hawon Jung.Presenter: Tim Harford Producers: Bethan Ashmead Latham, Jon Bithrey Editor: Richard Vadon Production Co-ordinator: Brenda Brown Sound Engineer: James Beard

Halving inflation, Scottish tidal power and have 1 in 3 women had an abortion?

Halving inflation, Scottish tidal power and have 1 in 3 women had an abortion?

One of Rishi Sunak's five priorities for 2023 is to halve inflation. Given prices are still rising, we discuss whether it's going be possible. Also does Scotland have more tidal power capacity than the rest of the world combined, as has been claimed? We look at competing claims about how prepared the NHS was before the pandemic, ask whether scrapping VAT on products like tampons and e-books has actually benefitted consumers and look at the claim that one in three women in the UK has had an abortion.

US National Debt: is $32 trillion a big number?

US National Debt: is $32 trillion a big number?

‘This episode was updated on 26th June to remove an error in how we quantified 32 trillion dollars’ The level of US government debt has just surpassed 32 trillion dollars. Negotiations over raising the borrowing limit once again went down to the wire a few weeks ago. But how concerned should we all be about how much the US government borrows? We investigate with the help of Kent Smetters, professor at the Wharton School of the University of Pennsylvania and Betsey Stevenson, Professor of Economics and Public Policy at the University of Michigan.

Mortgages, birth rates and does space contribute 18% to UK GDP?

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 Series Producer: Jon Bithrey Reporters: Beth Ashmead Latham, Nathan Gower, Charlotte McDonald Sound Engineer: James Beard Production Co-ordinator: Brenda Brown

Electric vehicles, 600 million bottles and does oral sex cause cancer?

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

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 Series Producer: Jon Bithrey Reporters: Jo Casserly, Nathan Gower Editor: Richard Vadon Sound Engineer: James Beard Production Co-ordinator: Brenda Brown(Woman looking for a flat to rent.

A short history of data

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

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.

NHS waiting lists, Voter ID and measuring divorce

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

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

Do 94% of marriages in Portugal really end in divorce?

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

Why is life expectancy falling in the USA?

Why is life expectancy falling in the USA?

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.

How much is the Coronation crown worth?

How much is the Coronation crown worth?

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 Pentagon Leaks and Fox News

The Pentagon Leaks and Fox News

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.

A groundbreaking new proof for Pythagoras’ Theorem?

A groundbreaking new proof for Pythagoras’ Theorem?

Pythagoras’ Theorem, explaining the relationship between the three sides of a right angled triangle, is one of the most famous in maths. It’s been studied and put to use for thousands of years. Now two US high school students say they’ve found a new trigonometric proof for the theorem, something many in the mathematical community believe to be impossible. We discuss Pythagoras’ Theorem, the importance of proofs in maths and the chances of this being a real breakthrough with mathematician, author and YouTuber Matt Parker.

Covid vaccines and false claims about miscarriage

Covid vaccines and false claims about miscarriage

Misinformation around covid-19 and vaccines is rife and as the data available increases, so do often misleading and even wild claims. This week More or Less examines multiple viral claims that the Covid 19 mRNA vaccines increase the risk of miscarriage. To explain where these incorrect figures come from and what the science actually tells us, we are joined by Dr Viki Male, senior lecturer in reproductive immunology at Imperial College London.

Do fungi kill three times as many people as malaria?

Do fungi kill three times as many people as malaria?

The smash hit TV show and video game ‘The Last of Us’ has spawned lots of curiosity about how worried we should be about the relatively unknown world of fungi. A figure in a recent BBC online article stated that fungal infections kill around 1.7 million people a year, about three times as many as malaria. In this episode we look at the both the global fight against malaria and David Denning, Professor of Infectious Diseases and Global Health at the University of Manchester explains the risks posed by fungal infections globally.

Does your jewellery contain stolen Brink’s-Mat gold?

Does your jewellery contain stolen Brink’s-Mat gold?

The Brink’s-Mat robbery remains to this day one of Britain’s biggest and most audacious heists. Six armed men stole diamonds, cash and three tonnes of gold bullion from a warehouse close to London’s Heathrow Airport in November 1983. It’s now the subject of a BBC television drama, The Gold, which includes the claim that most gold jewellery bought in the UK from 1984 onwards will contain traces of that stolen gold. But how true is that? Tim Harford and team investigate, with the help of Zoe Lyons from Hatton Garden Metals and Rob Eastaway, author of Maths on the Back of an Envelope.

UK vs European energy prices, falling excess deaths and is 5 grams of cocaine a lot?

Does the UK really have by far the highest domestic energy bills in Europe? We debunk a viral social media claim suggesting just that. Also the number of excess deaths has been falling in the UK - how positive should we be that we’re through the worst? Plus do we really have access to only 3% of rivers and 8% of the countryside in England – and after the conviction of former MP Jared O’Mara we ask whether 5 grams of cocaine is a lot.

Reoffending rates, Welsh taxes and the menopause

The Justice Secretary Dominic Raab says crime reoffending rates in England and Wales have fallen significantly since the Conservatives came to power. We ask whether he’s right and look more broadly at crime and conviction rates with former BBC home affairs correspondent Danny Shaw. Also we look at how much taxes in Wales might have to rise to pay for increases in NHS funding. We ask whether 13 million women in the UK are really menopausal. And we return to the debate that has sparked consternation among loyal listeners everywhere – should the word data be treated as plural or singular.

Florence Nightingale and how she visualised data

Florence Nightingale and how she visualised data

Florence Nightingale became one of the icons of Victorian Britain for her work as a nurse during the Crimean War and the public health improvements she successfully campaigned for later on. Tim Harford discusses how she and her ‘Nightingale Circle’ used spectacular diagrams to explain health statistics persuasively with RJ Andrews, editor of “Florence Nightingale, Mortality and Health Diagrams”.

Nurses' pay, ambulance times and forgotten female economists

Nurses' pay, ambulance times and forgotten female economists

How much do nurses in the UK earn compared with those elsewhere in Europe? Tim Harford and the team investigate. Also we have an update on ambulance response times, which were the worst on record in December but are showing signs of improvement. Should we use the word data in the singular or plural? The Financial Times has just changed its policy and Tim’s not happy. We look back at women who have made a key contribution to economics but have often been forgotten. And we hear how a spreadsheet error by the Office for National Statistics made the UK’s productivity appear to be one of the fastest improving in Europe.

The IMF and the UK economy, NHS staff shortages and British vs English

The International Monetary Fund says the UK will be the only major economy to shrink in size this year. We ask how much faith we should put in the IMF’s forecasts and look at some of the big economic challenges facing the UK. Also why the headline number of job vacancies in the NHS in England doesn’t tell the whole story of staff shortages. And why has there been such a dramatic change in whether people describe themselves as British or English?

Brexit and trade, pensioner millionaires and Hannah Fry on loyalty cards and cancer

Has trade with the EU increased since Britain left the European Union? Tim Harford and the team look at a claim suggesting just that. There’s a row over the renaming of a street in North London previously called Black Boy Lane – but how much has it really all cost? Also are there more pensioners in “millionaire households” than pensioners in poverty. And mathematician Hannah Fry talks about a new study suggesting cases of ovarian cancer can be detected by looking at spending on loyalty cards.

Can China's data on covid deaths be trusted?

Can China's data on covid deaths be trusted?

When the pandemic took hold, the Chinese government imposed a zero-Covid policy that aimed to contain the virus through mass-testing and strict lockdowns. But early in December, amidst widespread public protests and the spread of the omicron variant to more than 200 cities, those draconian, highly restrictive measures were lifted almost entirely. For the first time in just under two years, the majority of the country’s near one-and-a-half billion citizens were free to meet, mix and mingle where they pleased, triggering what experts believe is a gargantuan wave of covid infections and related deaths. Some analysts say death rates could be as high as15,000 per day. But the Chinese authorities are reporting five or fewer deaths a day. The numbers don't stack up so More or Less's Paul Connolly speaks to some of the world's leading experts and epidemiologists to work out if China's data on covid deaths can be trusted - and, if not, what the real death toll could be.

Irish pubs - a global numbers game

Irish pubs - a global numbers game

It's possible that the question we focus on in this week's programme occurred to you as you were sipping on an Irish Coffee in Bubbles O'Leary's in Kampala, Uganda: Where can the most Irish pubs be found - in Ireland? Or in all other countries combined? The popularity and sheer ubiquity of Irish pubs is a thing to behold. In 2015, the Irish Pubs Global Federation said there was approximately 6500 Irish pubs doing business outside the Emerald Isle - and our own research tells us there's at least one Irish bar in more than 160 of the world's 195 countries. But what is the secret, the recipe for global success? And can the More or Less team track down a definite number, thus answering the question some of you will have pondered whilst settling into a firelit Irish bar on a scorching hot day in rural Hawaii.

As the FIFA World Cup in Qatar gets underway, and the newly built stadia, lavish hotels and transport networks come to life, More or Less investigates just how much the Gulf nation has spent in the lead-up to the tournament. Reports claim the figure could be as much as $220 billion - that’s more than Qatar's annual GDP, and more than ten times higher than the 2014 World Cup in Brazil. At an estimated $15 billion, this was previously the most expensive tournament to date. With no access to Qatar’s accounts, and with very few official figures in circulation, More or Less has recruited some of the world’s leading experts in sports finance to crunch the numbers and to ask…is this really a $220 billion World Cup?Presenter: Paul Connolly Producers: Paul Connolly and Jon Bithrey Editor: Simon Watts Production Coordinator: Jacqui Johnson Sound Engineer: Rod Farquhar (Image: Al Wakrah Stadium, the second FIFA World Cup Qatar 2022 (TM) venue: The 2022 Supreme Committee for Delivery and Legacy via Getty Images)

What is inflation, why does it matter, and is someone to blame if it goes up? Understanding inflation will help you understand why your shopping is getting more and more expensive and why prices rarely seem to go down.

Everything you need to know about the economy and what it means for you. This podcast will cut through the jargon to bring you clarity and ensure you finally understand all those complicated terms and phrases you hear on the news. Inflation, GDP, Interest rates, and bonds, Tim Harford and friends explain them all. We’ll ensure you understand what’s going on today, why your shopping is getting more expensive or why your pay doesn’t cover your bills. We’ll also bring you surprising histories, from the war hungry Kings who have shaped how things are counted today to the greedy merchants flooding Spain with Silver coins.
