National Geographic has produced this set of four wonderful infographics to illustrate the World now that there are 7 billion people living on it.
Along side these, they have created the face of 7 billion, an image made up of 7000 human figures, each representing 1000000 people. This image is zoomable on the website to allow you to investigate closer.
I promise this is the last infographic post for a little while.
