This view of the population of the world by Alasdair Rae (@undertheraedar) is a view I really didn't know well. The US has 300 million people- about the same as Indonesia, but spread out over a much larger area. I had no idea about how dense East Africa was, or even Central America/ Colombia. This is a good reminder that half of of the world population lives in a relatively small part of the world, namely from west of India though China and out to Japan in the northeast and through Indonesia in the south.
