Freedom in Numbers

How many people in the world live in freedom? The BBC's Freedom 2014 season got Tim Harford and the More or Less team wondering about this. It's actually pretty hard to put a number on freedom, so Tim begins by looking at something more quantifiable: how many people live in a democracy? And are people in democracies happier? Tim Harford looks at the numbers with Simon Baptist from the Economist Intelligence Unit. Plus, he examines the price of a cup of coffee, and whether Ruth Alexander can be persuaded to pay for his. This programme was first broadcast live on the BBC World Service on 01 April 2014 from the Media Café at BBC New Broadcasting House in London.
