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. We ask whether the items featured really jump in value, or are we just seeing the price tag rise over the centuries in line with inflation? More Or Less reporter Charlotte McDonald heads down to the show to find out.

Computer Science and Socks Tim Harford speaks to Brian Christian, co-author of ?Algorithms to Live by: The Computer Science of Human Decisions?. How can the techniques of computer science help us in every-day situations? And, most importantly, which algorithm will help our reporter Jordan Dunbar sort out his socks?

The Irish Central Statistics Office has released figures showing that Ireland?s economy grew by 26% in 2015. That would make it the fastest growing economy in the world. But American economist Paul Krugman described this as ?leprechaun economics? as this growth rate is so unrealistically high. More or Less explores how multinational companies with headquarters in Ireland have led to an accounting headache for working out the country?s GDP.

Also, the mobile gaming app Pokemon Go has taken the US by storm and is now spreading across the world. But does Pokemon Go really have 26 million daily active users in the US? More Or Less investigates.

Protests have spread across the United States over the last few weeks. The protestors have been registering their feelings about incidents where police have shot and killed black men. High profile recent incidents resulted in the deaths of Alton Sterling and Philando Castle, and the protestors feel that minorities are being disproportionately targeted by the police.

On top of this, at a recent protest in Dallas a gunman shot and killed five police officers.

But what can the numbers tell us about the issue? How many people do police officers kill each year in the USA? And how many police officers are killed? Tim Harford investigates.

It?s often said that we should all be aiming to get eight hours of sleep a night. But could it actually lead you to an early grave? Research shows that sleeping for longer, or shorter, than average is associated with an increased risk of disease and mortality. But what?s causing the health problems, and should you really give up the lie-in? Ruth Alexander looks at the latest sleep science with Dr Gregg Jacobs from UMASS Medical Center, US; Professor Franco Cappuccio from Warwick University, UK; Professor Jim Horne of Loughborough University, UK; and Professor Shawn Youngstedt of Arizona State University, US.

Is Iceland the best football team in the world per capita? England suffered a 2-1 defeat to Iceland in the European Football Championship in France. This was embarrassing for England when you consider its population is 163 times bigger than Iceland?s. We take a look at whether Iceland is now the best performing football team in the world if you compare UEFA ranking to the size of each country?s population. Plus, we take a look at the chances of a young man in Iceland and in England getting to represent their country on the pitch.

Old versus young Brexit voters

Many media outlets have reported that it was predominantly the older generations in the UK who voted to ?Leave? the EU in a recent referendum, while those under 25 were keenest to ?Remain?. It has prompted many listeners to ask whether a referendum on this topic might yield a different result if held in a few years? time as the electorate changes. We attempt some back of the envelope calculations with Tom Chivers from Buzzfeed. But actually ? how good is the data available? How do we know how people voted or how they would vote in the future?

Following a referendum, the UK has voted to leave the European Union. Tim Harford and the team explore what that might mean for the UK?s economy. Most notably - what might be the impact on trade? We examine the economic forecasts from the government, and how the UK might manage its relationships with other countries.
