Comparison of the maps at their website is pretty amusing, I sort of pictured it as each country being represented by ballons on a map of the world with each one inflating or deflating depending on which map you look at.
Some were particularlay interesting. China has the most container cargo, the Indian sub continent the most population throughout history as well as the most trains and mopeds. The Immigration-emigration maps also add fuel to the fire currently in our headlines.
