This map, created by Bill Rankin, shows the human population density around the world. It is an equal-area projection, and centers on the Pacific, rather than the Atlantic. It makes plain sense that the two largest population centers on Earth, South Asia and East Asia, should be at the center of a global population map.
In the map below was taken from Wikipedia. Aside from being less visually nice, East Asia appears on the periphery of the map, and is much smaller than it really is relative to other landmasses, which consequently diminishes its importance in global issues.
