Landmark Numbers

A few reference numbers for judging whether another number is big or small.

The idea comes from Tim Harford's How to Make the World Add Up (published in the US as The Data Detective). Harford suggests carrying a handful of landmark numbers in your head, such as the population of the country or what the government spends in a year. When a new statistic comes along, you can check it against a landmark and tell whether it is big, small or simply implausible. The credit for the idea is his. Any mistakes in the numbers are mine.
