Brexit and trade; pensioner millionaires; and Hannah Fry on loyalty cards and cancer Feb 01, 2023

Show notes

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.

Ambulance response times, teacher pay and Irish pubs Jan 18, 2023

Show notes

How long are people really waiting when they call 999 for an ambulance? Tim Harford and the team examine in detail the sheer scale of delays in responding to emergency calls. We also ask why the NHS is facing a crisis when it’s got more funding and more staff than before the pandemic, with the help of Ben Zaranko from the Institute for Fiscal Studies. Plus we fact check a claim from one of Britain’s leading teaching unions about pay. And are there more pubs in Ireland or Irish pubs in the rest of the world?

A&E delays and deaths, religious identity in N Ireland and naming the monster numbers Jan 11, 2023

Show notes

Tim Harford and the team return for a new series of the number crunching show. With the huge pressures facing the NHS we ask how many people may be dying because of treatment delays in A&E. We hear what the latest census tells us about changing religious identity in Northern Ireland. We look at misleading claims about covid vaccines after the collapse of American football player Damar Hamlin. And we hear how More or Less has wielded its influence over how we all describe very large numbers.

Can China's data on covid deaths be trusted? Jan 07, 2023

Show notes

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 Dec 31, 2022

Show notes

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.
