New figures reveal that same-sex divorce rates are much higher among women than among men. The pattern is the same in Belgium, the Netherlands, Norway, Sweden and the UK. Everywhere where there are statistics on same-sex divorce it is the same sex doing the bulk of the divorcing. Tim Harford discusses why this may be with Marina Ashdade, economist at Canada’s Vancouver School of Economics and author of Dirty Money, a book which applies economic ideas to the study of sex and love.

This week BBC Radio 4’s All in the Mind programme announced the results of The Loneliness Experiment. It was a large survey conducted by the programme in collaboration with the Wellcome Collection. The largest survey into the issue of loneliness to date, said All in the Mind, while the accompanying BBC press release reported that “The survey results indicate that 16-24 year olds experience loneliness more often and more intensely than any other age group. 40% of respondents aged 16-24 reported feeling lonely often or very often, while only 29% of people aged 65-74 and 27% of people aged over 75 said the same.” In the editors' notes, the press release cautions that “This was a self-selecting sample, so people experiencing loneliness might have been more attracted to take part, inflating reported levels of loneliness.” But much of the reporting by other BBC outlets and the wider media was not so restrained. Tim Harford speaks to Deirdre Toher from the University of the West of England about why the survey's results need careful interpretation.Listeners have been asking us to explain the schools funding row. When headteachers marched in protest at school spending last week, the Minister for School Standards, Nick Gibb, went on BBC Radio 4's Today programme to say "We are spending record amounts on our school funding.

This week we take a look at some of the statistics which have caught our attention at the World Cup. There has been much debate in both the press and social media about the large distances which Russian football players have run in their first two games. We look at how they compare to other teams and what it might signify. Also –is it just bad luck that Germany has crashed out of the competition?

The World Cup starts this week and the More or Less team is marking the event by looking at the data behind all the World Cups since 1966 (our data shows that this was the best world cup because England won). We’ll answer all football fans most burning questions; which World Cups have seen the most shots, fouls, dribbles and most importantly goals? Do the statistics back up the reputations of famous players like Pele, Cruyff, Maradona and Paul Gascoigne? And which of them actually committed the most fouls at one World Cup? Ben Carter talks to Author and Opta Sports football statistician Duncan Alexander about how the ‘beautiful game’ has changed…through numbers. (Picture: The World Cup, credit: Shutterstock)

How do you count the number of people sleeping rough? According to the latest official figures around 4700 people were sleeping in the streets in the autumn of 2017. And that got us thinking.
