More or Less

This year, the UK has had its hottest May and June days on record, with the mercury hitting the high thirties. But while the markings on a thermometer seem scientific and regular, the way we split up our calendar does not. Why, for instance, does May have 31 days and June have 30? To find out why our calendar has its modern form, we speak to Kristen Lippincott, former director of the Royal Observa...

Tim Harford investigates some of the numbers in the news. This week: (00:42) Former Chancellor of the Exchequer Sir Jeremy Hunt argues that you can earn far more on out of work benefits than you can on the minimum wage. We argue his figures are deceptive - and we’ve done the homework to prove it. (09:09) As the heatwave rises to a crescendo, people are saying that wet bulb temperatures could hit c...

This surprising claim was spotted circulating on social media: ‘The United States has surpassed China and North Korea in deaths from malnutrition’. The claim used analysis from the Global Burden of Disease database for their sums. The data does indeed show that the US records more deaths from Malnutrition than China and North Korea. The rate in the US was 2.8 deaths per 100,000 compared to just 1....

Tim Harford investigates some of the numbers in the news. This week: (00:31) Claims have circulated on the internet that Europe sees a particularly high number of deaths from heat waves, especially when compared to the US. Can we really compare the statistics, and is air conditioning a silver bullet? (06:59) Sainsbury’s are making the switch from brown to white eggs, on the basis of claims about t...

The Great Crash of 1929 has faded into history, but financial journalist and author Andrew Ross Sorkin argues it holds vital lessons for today. Andrew came into the studio in London to discuss what we can understand about the crash in numbers, from ticker-tape running hours behind plunging stock prices to crucial metrics that sound the alarm bells before a financial crisis. Are they sounding today...

Tim Harford investigates some of the numbers in the news. This week: (00:32) The internet is abuzz with the claim that twenty-seven young migrants are hired for every British young person. We explore the truth behind this misleading claim. (08:40) Last year two nerds made a bet on our programme.

In certain corners of the internet some suspicious numbers are cropping up again and again. People claiming that 400 churches have been burnt to the ground or attacked in an assortment of countries, including France, the US and Canada. So, what is going on? Is there a spate of anti-Christian crime sweeping the globe? We look into what the data actually tells us. If you've seen a number in the news...

Tim Harford investigates some of the numbers in the news. This week: The Daily Express claims that ‘Migrants will get half of all new homes’, based on a calculation from the Conservatives. We explain why that’s not what the numbers say, and ask what the Conservatives own record on migration and housing tells us. Does one in five Welsh pupils leave school functionally illiterate? We take a dive int...

On the 17th of May the World Health Organisation declared a new outbreak of Ebolavirus in the Democratic Republic of the Congo as an International Emergency. Ebola virus is an extremely nasty viral disease with a high death toll. But despite its severity, very little is known about the number of infections in this current outbreak, in part because this particular species of Ebola is a rare one. He...

Tim Harford investigates some of the numbers in the news. This week: Headlines have claimed that “healthy life expectancy” in the UK has fallen by two years. What does this actually mean? A new government report estimates that HS2 will cost almost double its original estimate. We ask where the money’s gone. Chancellor Rachel Reeves has reduced VAT on theme parks, aquariums and other summer fun. Bu...

What does it mean if you say that something is an epidemic? In the case of a virus, it usually means that it is spreading rapidly and that more and more people are getting infected. When a disease isn’t on the rise but is there in a population at a reasonably steady level, we tend to say that the disease is endemic. But what if the thing you’re talking about is not a virus, but a feeling? In 2023,...

Tim Harford investigates some of the numbers in the news. On the programme: Last week, Annunziata Rees-Mogg took to X to post a claim about the proportion of sex offences in Dorset that are committed by asylum seekers, writing that “asylum seekers make up 0.8% of Dorset’s population and 44% of alleged sex offenses. So unbelievable I had to check.” We checked too, and the number isn’t right. In the...

It’s said that AI could soon be coming for the jobs of artists, lawyers, and software engineers. But it might now also be threatening a role at the height of academia – are pure mathematicians safe? Last month, a Stanford mathematician woke up to an email, claiming to have the solution to a problem he'd been working on for seven years - a 60-year-old conundrum known as "Erdos Problem 1196".
