Professor Kenneth Rogoff says that the UK vote to leave the EU was a “Russian roulette for republics”, with an ‘absurdly low bar for exit, requiring only a simple majority’, with no supermajority, second referendum or parliamentary confirmation vote required.

Many voters did not have had a clear idea of what they were voting for or of its consequences, and many now seem to regret it. But the results did confirm the existence of a diffuse anger among the UK population. Read more

The chain of events that led to Brexit will be examined in great detail — and much anguish on the Remain side — for years to come. Rapid changes in the UK’s political climate undoubtedly played a part, and global events including the Great Recession and recent European migrant crisis have left their mark.

But for now we can focus on what we know in the immediate aftermath of the vote: the distinguishing characteristics of the areas of Britain that voted for either side. Read more

Polling has dominated coverage of the UK’s EU referendum for the last month, with the focus shifting between the polls’ reliability following their 2015 misfire, the methodological challenges pollsters face, and the Remain vs Leave race itselfRead more

Political journalists have become exceedingly wary of pollsters since they called last year’s general election wrongly. Are they right to be? The performance of major polling companies in this referendum could make or break their reputations – get it wrong again and the fury of Fleet Street will be unconstrained.

But there’s good reason to feel that hacks should have learned some lessons too – the first being, properly understand what it is that you are reporting. Here are a handful of key points to bear in mind when in the coming days we consider the pollsters’ performance in this referendum. Read more

Remain led by several points in late 2015, but saw its lead eroded at first gradually, and then quickly as 2016 wore on, before Leave went ahead over the last weekThe way our model calculates the average from the remaining five polls in its basket after outliers are removed is completely unchanged, but the polls in that basket should be more representative of where the ‘true’ opinion of the electorate lies.

After this change, our poll-of-polls has Leave on 45, two points ahead of Remain. Read more

Spain lead the Financial Times' predictions for Euro 2016, just ahead of Germany and then hosts FranceThe European Football Championships are upon us, and with them an eclectic mix of prediction models from media organisations, financial institutions and independent statisticians. To assuage our FOMO (fear of missing out, for the non-Millennials), the FT has joined in with one of our own.

Spain are favourites to lift the trophy, narrowly ahead of Germany and hosts France, based on our method which uses Champions League appearances and players’ market values to determine each team’s strength. This trio of teams comes in well ahead of the other 21 countries taking part.

Read on for details of the model and how it compares to the betting markets. Read more

The US and the UK have huge trade deficits in goods particularly with China, but they run the biggest surpluses in services. Financial services are particularly strong in the UK, while tourism is prominent in Spain and IT in India.

Two weeks out from from Britain’s historic EU referendum, opinion polls are dominating the debate. The question is: are they adding or removing clarity about the eventual outcome?

Today we published an overview of some of the challenges facing pollsters as they look to demonstrate that the 2015 general election mis-fire was a one-off. What follows here is a look at how some of these issues are affecting our own poll-of-polls — and how we might deal with them — as well as an exploration of some of the alternatives to pure polling when it comes to forecasting the result on June 23. Read more

London’s population overtook New York’s in 2014 and last year surpassed its pre-World War II peak for the first time ever. Yet there are increasingly news stories about how the UK’s capital is becoming a place where people work but don’t live, or how sharply rising house prices are forcing out the poor, the young or those with families.

What is actually happening? How to square the anecdotal evidence with the fact that London adds as many people as the entire city of Bath (>100,000) to its population every single year?

Just two weeks to go before Britons can finally stop those Eurocrats in Brussels from dictating how much cleavage barmaids can display when serving customers.

Wait – what?

Discussions over the UK’s membership of the EU and how it affects the British have been crowding the airwaves for years. Read more

Earlier this month Londoners voted in Sadiq Khan as mayor. The Labour candidate won 59 per cent of the vote and in so doing became the first Muslim mayor of a major European capital. But beyond the top-line figures, what do we know about how the election was won, and who voted for whom?

To answer these questions, we downloaded 140 datasets from the 2011 census, describing the demographic and socioeconomic composition of each of London’s 570 electoral wards: the same units over which the mayoral election vote was tallied. Read more


Leicester were bottom of the Premier League on April 10 2015, but a year later had climbed to the top, winning 91 points along the way. No team beginning at the foot of the top flight has ever won that many points* over the subsequent year since English league football began Read more

This week the European Commission let Italy off the hook, granting the country extra flexibility – to the tune of 14 billion euros – in its debt reduction targets for 2016.

The extra “flexibility” includes allowances for investments (0.25 per cent of GDP), for the refugees crisis (0.04 per cent of GDP) and for extra security measures (0.06 per cent of GDP). In return the Commission wants a ‘clear and credible commitment’ from Italy that the country will respect its budget targets in 2017. Read more

Life expectancy has increased sharply across advanced nations over the last fifty years. In 2014, people residing in OECD countries were, for the first time, expected to live beyond 80 years according World Bank data. That’s 13 years longer than in 1960.

But not all countries improved at the same pace Read more
