Visual Demography

I can (and often do) babble on for hundreds of words what this does via picture. Here is your order.

Picture in your mind the 4 nations you would least like to populate and start to dominate the planet in 2050 on a basis of civilization, culture, human rights, etc. Then picture in your mind the 4 nations you wish the world was more like in 2050. Then take your mouse and put it over those nations. Note for them the time it takes for the next death, and the next life. If more people are dying than being born - that nation is going the way of the Dacians, Assyrians etc. If they are breeding like rabbits - those are the ones that will either fill the gap - or fight their way into it. Be humble.
