Tim Harford explores why such a range exists and what methods are used to count those killed during war. Meanwhile he discovers that Iraq's population has been growing strongly over the same period. Plus, mathematician and comedian Matt Parker presents his guide to the imperial measurement system. This programme was first broadcast on the BBC World Service.

Most deaths occur in this week of the year - Tim Harford asks why. He also asks: are there really two million millionaire pensioners in the UK, and how many people have died in Iraq since 2003? Plus, mathematician and comedian, Matt Parker, apologises for his previous apology.
