The World's Population Density, Visualized

It's difficult to get a handle on the population density around the world. Fortunately, this visualization makes it a little easier to get your head round.

Put together by Derek Watkins, it's actually interactive: you get to use a slider to shift the population density and see it change before your eyes. You should head to his website to try it out for yourself. The image above shows the areas around the world that home 5 people per square mile or more.
