More or Less: Behind the Stats - Are 4% of young women in the UK on OnlyFans?

Tim Harford investigates some of the numbers in the news, and in life. This week:

We debunk a false claim that the hotel bill for immigrants is the size of the tax bill for Manchester.

An article in the Spectator claimed that 4% of women aged between 18 and 34 in the UK are OnlyFans creators. We track down the source and discover that it is not very good.

Do people in Scotland use much more water than people in Yorkshire? If so, why?

And we examine a popular claim that today’s working mothers spend more time with their children than your stereotypical 1950s housewife did.

Make sure you get in touch if you’ve seen a number you think Tim and the team should take a look at. The email is moreorless@bbc.co.uk

Start the Week - The Idea of Genius

We think we know what a genius is: a tortured poet; rebellious scientist; monstrous artist; or a tech disruptor. You can tell what a society values by who it labels as a genius says Helen Lewis in her new book, The Genius Myth: The Dangerous Allure of Rebels, Monsters and Rule-Breakers. From Leonardo da Vinci to Elon Musk, she asks if the modern idea of genius, as a class of special people, is distorting our view of the world.

With ten platinum albums Tupac Shakur was one of the stars of hip hop music when he was murdered at the age of 25. His music was very influential and his name is also associated with the legacy of Black Panther politics. In Words for My Comrades: A Political Biography of Tupac Shakur, Dean Van Nguyen argues that while much of the energy of the Black political movement was absorbed by the commercial music culture of the 1990s – Tupac’s contribution lives on today.

Gertrude Stein was considered a genius by some, a charlatan by others. She posed for Picasso’s portrait; hosted Matisse and Hemingway in Bohemian Paris; and she dazzled American crowds on her sell-out tour for her sensational Autobiography of Alice B Toklas, a version of the relationship with her partner. Francesca Wade’s new book Gertrude Stein: An Afterlife, explores the creation of the Stein myth.

More or Less: Behind the Stats - Could you be hit by a falling satellite?

The number of satellites orbiting our planet has been rapidly increasing in recent years. But what are the risks when they start falling back down to earth?

The European Space agency estimate that by 2030 there will be 100,000 satellites in orbit. We look at whether that estimate is realistic and what it means for those of us living on the ground below, with the help of Jonathan McDowell and Fionagh Thomson.

More or Less: Behind the Stats - How do you make something 10-times more lethal?

What does the government mean when it commits to developing a “10-times more lethal” army?

Why was the much-missed Sycamore Gap tree said to be worth a strikingly exact £622,191?

Are there really twice as many people teaching Yoga as there are in the fishing industry?

Is the number of workers per pensioner really falling from 4 to 3 to 2? And what did Donald Trump mean when he said the price of eggs had fallen by 400%?

Tim Harford investigates some of the numbers in the news. If you want us to look at a number you think looks a bit suspicious, email the team - moreorless@bbc.co.uk

Start the Week - Hidden spaces and dangerous places

There is a parallel world which operates under different rules and benefits those with money and power. That’s the argument made by the journalist Atossa Araxia Abrahamian in her new book The Hidden Globe: How Wealth Hacks the world. She traces the rise of a freeports, charter cities and offshore havens.

Danny Dorling contends that we’re not very good at spotting the real crises we face today. In The Next Crisis: What We Think About the Future, he explains why the most urgent global crises are rarely the ones that hit the headlines. From inequality, immigration and international conflicts to climate change, pandemics and tsunamis, he challenges our assumptions about the threats we face and how we should think about our uncertain future.

It is time to reclaim online spaces, says Adele Zeynep Walton. In her new book Logging Off: The Human Cost of Our Digital World she explores how the price of the connections and conveniences of online life has been the mental health of a generation. She says that social media platforms and digital technology are making us vulnerable and it is time these spaces were governed and regulated.

More or Less: Behind the Stats - Is the world’s population being miscounted?

Exactly how many people live on our planet is one of those difficult-to-answer questions. The UN estimates is 8.2 billion, but that’s largely based on census data, which is certainly not a perfect measure.

So when a recent study from Finland found that rural populations around the world had been underestimated by 50 to over 80%, the media got quite excited. This would be a big error - a 50% underestimate would mean the actual number of people in an area is double the number they thought there were.

One newspaper in Spain - El Mundo - did its own sums and said this meant there were potentially 2 billion more people in the world than we currently think there are.

But is it what the researchers in Finland actually meant?

“Absolutely not,” says Josias Lang-Ritter, a researcher from University in Finland and a co-author of the study.

Tim Harford speaks to Josias to figure out the right way of understanding the study.

More or Less: Behind the Stats - Does the average American have fewer than three friends?

Tim Harford is here to sprinkle a refreshing shower of statistical insight over the parched lawns of misinformation.

This week, we try to unpick the confusion over a claim made by London Mayor Sadiq Khan about the contribution skilled immigrants make to the nation?s finances.

Mark Zuckerberg says that the average American has fewer than 3 friends. Is he right?

Two doctors claim that up to 90% of Alzheimer?s disease can be prevented. Are they wrong?

And Tim interviews an American, Catholic, philosopher of religion called Robert Prevost. Is he the pope?

Start the Week - The uses and abuses of the atom

Professor Frank Close looks at how the quest to understand radioactivity and the atomic nucleus was initially fired by scientific curiosity and then by more human motives. What began as collaboration between scientists in the pursuit of atomic energy was overwhelmed by politics and opened the way to the possibility of nuclear war. Frank Close’s Destroyer of Worlds: The Deep History of the Nuclear Age: 1895-1965 shows how scientific knowledge is often advanced by personal convictions and relationships and takes us into the rooms where discoveries and decisions were made.

Nuclear energy is the most promising tool that we have to tackle the climate emergency, so argues Tim Gregory in his new book Going Nuclear How the Atom Will Save the World. He says it is time to debunk the myths about nuclear waste and radiation and that nuclear power is reliable and safe. Harnessing the atom is our best hope of providing abundant and clean energy to ensure an equitable and prosperous future.

For Baroness Natalie Bennett, former leader of the Green Party, nuclear has been a continual disaster. As an energy source nuclear it has been impractical, inflexible and unreliable; a dinosaur technology whose use has declined. She believes that the continued appearance of nuclear in policy debates is a distraction from renewables and energy conservation. She believes that we have not found an adequate solution to the problem of nuclear waste. And in the field of defence, the majority of countries want a ban on nuclear weapons.

More or Less: Behind the Stats - Factchecking the Trump administration?s Autism claims

Picking Robert F. Kennedy Jr., a known vaccine sceptic, as the Secretary for Public Health might not be the most ?out there? thing the Trump administration has done but it certainly raised some eyebrows. Since his appointment Kennedy has been on a mission to ?Make America Healthy again? and has set his sights on finding ?the cure? for Autism. Autism Spectrum Disorder is a neurological and developmental disorder that can affect how someone communicates, socialises, learns and behaves. In the 1980?s one study estimated that 4 in 10,000 (1 in 2500) children in Wisconsin had an Autism diagnosis. Recent data from the Centres for Disease control states that 1 in 31 eight year olds in the US have the condition. Why have the numbers gone up? Is it due to environmental toxins as Robert Kennedy suggests or does the answer lie in the counting?

Start the Week - Hay Festival: exposing the secrets of rubbish

In front of an audience at the Hay Literary Festival Tom Sutcliffe talks to The archaeologist and presenter of the hit TV show, The Great British Dig, Chloë Duckworth, who explains how every object tells a story. She reveals how even the rubbish our ancestors threw away can offer a window on the past and forge a connection with the present day.

Business journalist Saabira Chaudhuri's new book Consumed, examines how companies have harnessed single-use plastics to turbocharge their profits over the last seventy years. Consumer goods makers have poured billions of dollars into convincing us we need disposable cups, bags, bottles, sachets and plastic-packaged ultra-processed foods. Taking in marketing, commercial strategy and psychology, she explains just how we got here.

The paleobiologist Sarah Gabbott is more interested in looking at how what we throw away today becomes the fossils of tomorrow. Discarded (co-authored with Jan Zalasiewicz) highlights the cutting-edge science that is emerging to reveal the far-future human footprint on Earth.
