More or Less

How can journalists improve their use of statistics in their reporting of the world around us? It’s a question US academics John Bailer and Rosemary Pennington tackle in their new book Statistics Behind the Headlines. They join Tim Harford to talk about how journalism can be improved by asking the right questions about numbers and using them in the wider context of a story.

Lula Da Silva has pledged “zero deforestation” in the Amazon as he prepares to become Brazil’s next president, in contrast to the policies of outgoing leader Jair Bolsonaro under whom the destruction of the rainforest has soared. On this edition of More or Less we ask how much of the Amazon has been lost and whether Lula’s aim of zero deforestation can be achieved.Presenter and producer: Jon Bithrey Editor: Simon Watts: Sound engineer: David Crackles Production Co-ordinator: Jacqui Johnson(Image: Aerial view of the deforestation of the Amazon: Reuters/Ueslei Marcelino/File Photo)

This week, China released its third quarter GDP figure. At 3.9%, its rate of economic growth is better than many analysts expected, but still significantly short of the 5.5% target the Chinese government had set itself. There was an unprecedented delay in releasing this particular GDP stat - and that delay coincided with the 20th Chinese Communist Party congress. President Xi Jinping was reappointed for a historic third term at the twice-a-decade gathering. Some analysts found the delay suspicious. Did President Xi postpone the release of the GDP figures so it wouldn’t tarnish the congress? And can the figure of 3.9 per cent be trusted anyway?

The former head of the US Federal Reserve Ben Bernanke is named as one of three winners of the 2022 Nobel Prize in Economic Sciences for his work on how banking collapses were a major factor in the Great Depression of the 1930s. He shares the prize with two fellow US academics, Douglas Diamond and Philip Dybvig. Tim Harford discusses the significance of their work focusing on the role of banks and why their smooth functioning is so important to society.

A survey from a mental health charity suggested that more than a third of British teenagers had been prescribed antidepressants. We debunk the figure. Also we investigate a tweet from the UK Treasury about how much homebuyers will save in stamp duty. Plus how Mexico has been hit by earthquakes three times on the same day of the year - what are the chances? And how incorrect figures from the government have given a false picture of the number of cars on Britain’s minor roads.

This week NASA slammed a spacecraft into an asteroid in the hope of diverting its course. The Double Asteroid Redirection Test or DART mission will help scientists understand how easy it would be protect Earth if one was headed in our direction. More Or Less first discussed this in 2016 with a little help from the movie Armageddon – with listeners getting in touch once again we ask how many asteroids are really out there and how dangerous they might be to Earth.

The value of the pound against other currencies has been incredibly volatile ever since the Chancellor’s ‘mini-budget’. We ask how much we should worry and look at how much taxes will really fall. Also did 4.1 billion people really watch the Queen’s funeral? Gas prices are falling – so why aren’t energy bills? There are early signs that new covid variants could cause another spike in cases over the winter. And with the government lifting a moratorium on fracking, we ask how seismic a number the current limit of 0.5 on the Richter scale actually is.Presenter: Tim Harford Series Producer: Jon Bithrey Reporters: Charlotte McDonald, Nathan Gower Production Coordinator: Jacqui Johnson Sound Engineer: James Beard

Ukraine has reportedly recaptured nearly 10,000 square kilometres of territory that had been occupied by Russia. We ask where the numbers come from and what they mean. Plus with Norway supplanting Russia to become Europe’s biggest supplier of natural gas, we ask how much money the country is making from the increased demand and higher prices.Presenter: Tim Harford Producer: Jon Bithrey Editor: Richard Vadon Production Coordinator: Jacqui Johnson Sound Engineer: Neil Churchill
