More or Less

Ever since a BBC article highlighted the use of baby boxes in Finland they have become a bit of a phenomenon. They’re not new though Finland has been doing this for 75 years. The simple cardboard boxes are given to families for their new born babies to sleep in. Since their introduction cot death and has fallen and child health improved. Governments and individuals across the world have adopted them and companies have sprung up selling them. But think about for minute – can a cardboard box on its own really have such a huge effect – Elizabeth Cassin and Charlotte McDonald have been looking at the truth behind the story.

Hidden Figures, the film, has been nominated for three awards at the Oscars and has been a box office hit in the US. It tells the little-known story of a group of African American women and their contribution to the space race in the 50s and 60s. We explore the history of how these women were recruited by Nasa and put to work on complex mathematical tasks – at a time when African Americans and women were far less likely to be employed in such jobs.

A huge hole was left in the world this week with the death of the Swedish statistician Han Rosling. He was a master communicator whose captivating presentations on global development were watched by millions. He had the ear of those with power and influence. His friend Bill Gates said Hans ‘brought data to life and helped the world see the human progress it often overlooked’. In a world that often looks at the bad news coming out of the developing world, Rosling was determined to spread the good news, extended life expectancy, falling rates of disease and infant mortality. He was fighting what he called the ‘post-fact era‘ of global health. He was passionate about global development and before he became famous he lived and worked in Mozambique, India and the Democratic Republic of Congo using data and his skills as a doctor to save lives. Despite ill health he also travelled to Liberia during the Ebola outbreak in 2014 to help gather and consolidate data to help fight the outbreak. On a personal level he was warm, funny and kind and will be greatly missed by a huge number of people.

How much water should you be drinking? There’s some age-old advice that suggests you should be drinking eight ounces (230 ml) eight times a day. Some people even advise you should be drinking this on top of what you normally drink. There is lots of advice out there but how do you know when you’ve had enough or if you’re drinking too much. With help from Professor Stanley Goldfarb from the University of Pennsylvania, Wesley Stephenson finds out. (Image: Hand holding a glass of water. Credit: Charlotte Ball/PA Wire)

There have been reports that those radical Swedes have decided to reduce the working day to just six hours because, it has been claimed, productivity does not suffer. Before you all rush to the Swedish job pages this is not quite the case – but there have been trials in Sweden to test whether you can shorten people’s working hours without having an effect on output. Tim Harford talks to our Swedish correspondent Keith Moore about what the trials have found. He also speaks to professor John Pencavel, Emeritus Professor of Economics, at Stanford University, and finds that reducing working hours may not be as radical idea as it first appears.

It’s now a year since the UN set its new Sustainable Development Goals to try to make the world a better place. They include 17 goals and a massive 169 targets on subjects like disease, education and governance. But some people like Bjorn Lomborg are saying that there’s just too many and they are too broad, and left like that will never achieve anything. Is he right – and is there a better way to make the world better and stop some countries lagging behind? Wesley Stephenson and Charlotte McDonald find out.

Polling on the first TV debate between Hillary Clinton and Donald Trump appears to be divided over who won it. But not all polls are equal. If the people being polled aren’t representative of the population at large, then their responses may not tell you anything useful. And when internet polls can be hijacked by online activists, they can throw up some pretty strange results.(Photo: Donald Trump and Hillary Clinton first presidential debate. Credit: Getty Images)

This week Donald Trump claimed that there are some inner city areas in the US which are suffering from the worst crime rates ever. They are so dangerous, he says, that Afghanistan is safer than many of these areas. But could this be true? We take a look at crime in the US and assess whether you can compare it to a conflict zone such as Afghanistan. (Image: Chicago - Neighbourhood residents watch as police investigate a homicide scene.

Can economics help us work out the perfect amount to spend on a wedding gift? Our reporter Jordan Dunbar is in a tricky situation-he’s heading to an old friend’s wedding and needs to figure out how much to give as a gift without breaking the bank. Luckily, economist Maria Kozlovskaya is on hand to talk about her findings on what factors we need to consider for gift giving, as well as preserving Jordan’s friendship and wallet.

Over the last two months the Government in the Philippines has been encouraging the police to clampdown on the illegal drug trade. The new President, Rodrigo Duterte, went as far as saying that citizens could shoot and kill drug dealers who resisted arrest, and the killings of drug suspects were lawful if the police acted in self-defence. The press have been reporting numbers of how many people have been killed during the crackdown – but how much trust can we put in these figures? Lottery wins We interview Adam Kucharski, author of The Perfect Bet, to find out if maths can give you an edge to playing the lottery or gambling.

It is a commonly held belief that if women spend enough time together, their bodies start to communicate through chemical signals, known as pheromones. Eventually the women’s bodies will start to menstruate at the same time. But where does this idea come from? And is it really true? We look at the evidence and wonder – could it be down to chance?

Britons entitled to Irish passports After the Brexit vote in June, so many Britons applied for Irish passports that Ireland’s foreign minister had to ask them to stop – pointing out that the UK remains, for now, in the EU. If some of the figures that have been quoted are correct, the Irish passport service may find itself completely inundated in future. But does one in four Britons really have Irish heritage? We reveal the dubious history of that number and attempt to estimate the number of Britons who are actually entitled to dual nationality with Ireland.Do women’s periods sync? It is a commonly held belief that if women spend time together, their bodies start to sync and they will have their periods at the same time. But where does this idea come from?

Statistics suggest that officially about half of the countries in the world have abolished Capital Punishment, and a further 52 have stopped its use in practice. But we tell the story behind the numbers and show why the picture is more complicated. We speak to Parvais Jabbar, co-director of the Death Penalty Project.

The “gender pay gap” This topic has been in the news this week after the Institute for Fiscal Studies published research showing women end up 33% worse off than their male counterparts after they have children. But earlier in the summer, Fraser Nelson wrote in the Telegraph that the pay gap is “no longer an issue” for women born after 1975. Can both assessments be true? And could the label “gender pay gap” be hindering our understanding of what really lies behind the numbers?The cost of a hospital If a politician or commentator wants to underline just how wasteful a piece of expenditure is, a common strategy is to compare it to the number of hospitals you could build instead. Of course, hospitals are positive things – we all want more, right? But just how much is a hospital? Is it really a useful unit of measurement? We speak to health economist John Appleby.Corbyn Facts As Labour members begin voting on the party leadership, we investigate some of the claims made on the “Corbyn Facts” website set up by Jeremy Corbyn’s campaign. Did he really give 122 speeches on the EU referendum during the campaign? Were this year’s local election results as good as Labour’s best performance under Ed Miliband? We look at what the numbers tell us.Death Penalty abolition Statistics suggest that officially about half of the countries in the world have abolished Capital Punishment, and a further 52 have stopped its use in practice.

With high profile attacks in Brussels, Nice and Munich, you might think that 2016 has been a particularly bad year for terrorism in Europe. But what happens when you put the numbers in historical context and compare them with figures for the rest of the world? More Or Less hears from Dr Erin Miller of the Global Terrorism Database and Harvard psychology professor Steven Pinker.(Image: A man wrapped in a Belgian flag holds a candle as people gather at a makeshift memorial on Place de la Bourse two days after a triple bomb attack hit.

Is 2016 an unusually deadly year for terrorism?In a joint investigation with BBC Newsbeat and BBC Monitoring, we’ve analysed nearly 25,000 news articles to assess whether 2016 so far has been a unusually deadly year for terrorism. It certainly feels like it. But what do the numbers say? We estimate that, between January and July this year, 892 people died in terrorist attacks in Europe – making it the most deadly first seven months of a year since 1994. But the vast majority of those deaths have been in Turkey. The number for Western Europe is 143, which is lower than many years in the 1970s. Dying ‘at the hands of the police’This week retired footballer Dalian Atkinson died after being 'tasered' by police. His death has renewed concerns about the number of people who die after coming into contact with the police. Recently it was claimed that one person a week dies ‘at the hands of the police’ and that ‘black people are disproportionately affected.’ We take a look at the numbers.Olympic predictionsAs the Games in Rio draw to an end, we look back at the medal predictions we made before they started. Which countries have performed as expected? And which failed to meet our expectations?The cost of a wedding giftCan economics tell us how much to spend on a wedding gift?

Luckily, economist Maria Kozlovskaya is on hand to explain her findings on our ‘internal exchange rate’ for gift giving. Can she preserve Jordan’s friendship while protecting his wallet?

World Records are being set at a much faster rate in swimming than in other sports. At the Rio Olympics, British swimmer Adam Peaty managed to break the men's 100m breaststroke world record twice in two days. Tim Harford speaks to swimming coach, Rick Madge, about the reasons swimmers keep getting better results in the pool. Also, science writer Christie Aschwanden makes the case for the virtues of the 5,000 metre race. She says that in recent times it has become very popular for people to train to run a marathon. But when you look at the numbers, is the 5K a better distance? Presenter: Tim Harford Producer: Charlotte McDonald

It has been reported that Prime Minister Theresa May is planning on lifting the ban on creating new grammar schools. Chris Cook, Policy Editor for Newsnight, has been looking at the evidence for whether these selective schools improve exam performance or social mobility. Swimming World Records New world records are being set in swimming at a much faster rate than other sports – but why? Tim Harford speaks to swim coach and blogger, Rick Madge about the reason swimmers keep getting better results in the pool. Why do other sports, like athletics, not seem to have the same continual improvements in results?Teenage girls aren’t so bad after all This week’s Desk of Good News challenges the concept that teenage girls and young women are badly behaved.

How can we use statistics to predict how many medals each nation will win? We speak to Dr Julia Bredtmann, an economist at the RWI Leibniz Institute for Economic Research. She has come up with a model to predict how many medals each country will win, along with her colleagues, Sebastian Otten, also from the Leibniz Institute, and Carsten Crede of the University of East Anglia.Some countries like the US and China have a large population and GDP, but a number of countries do very well for their size and wealth. Julia explains the different factors you have to consider to predict Olympic success.

The Government says that since the introduction of the 5p fee for single use plastic bags their use has plummeted. We take a look at the numbers.Olympic Medals at Rio 2016 The Olympic Games are with us again. So how can we use statistics to predict how many medals each nation will win? We speak to Dr Julia Bredtmann, an economist at the Leibniz Institute for Economic Research.Income inequality Politicians and commentators often claim that the rich are getting richer while the poor are getting poorer. But what do the numbers actually tell us about income inequality in the UK? Tim Harford interviews Jonathan Cribb of the Institute for Fiscal Studies, the co- author of a comprehensive analysis of Living Standards, Income Inequality and Poverty in the UK.Desk of Good News – Maternal mortality rates The number of women dying in childbirth is falling around the world. In 1990, maternal mortality rates were 385 deaths per 100,000 live births Today there are 216 deaths per 100,000 live births. This means the death rate is down by nearly half. The Coastline Paradox Why is it so difficult to measure coastlines? The further you zoom into the detail of a coastline, the longer it becomes. This is referred to as ‘The Coastline Paradox’. We speak to Mairi Walker, a mathematician at the University of Edinburgh, and Danny Hyam, from The Ordnance Survey - the UK government agency responsible for mapping our coastlines.

How can the techniques of computer science help us in everyday life? We speak to Brian Christian co-author of ‘Algorithms to Live by: The Computer Science of Human Decisions’. He argues that the techniques of computer science can help us manage everyday situations in a more logical and efficient manner. So which algorithm can help solve the problem of odd socks? And what is the most efficient way of alphabetising your book collection? Tim Harford investigates.

Many news outlets have reported this week that a Waitrose supermarket pushes up house prices in the surrounding area. It’s based on research that also suggests that other supermarkets have a similar but smaller effect. We take a highly sceptical look at the correlation.Statistics and the EU referendum campaign We look at how the two campaigns, the media, and the much-discussed “experts” used statistics during the EU referendum campaign. Tim Harford interviews Will Moy, director of Fullfact, and Paul Johnson, director of the Institute for Fiscal Studies.Antiques Roadshow BBC One’s Antiques Roadshow is a hugely popular television programme, where experts examine and value antiques and collectables.
