Nevermind population or GDP. Those metrics aren't important. This map by Jody Sieradzki of Dadaviz Research shows what matters in political geography: the hair colors of the heads of government around the world.
Blondes thrive in northern Europe and baldness prospers in Africa. There's a sweep of grey hair around the middle of the world. Sadly, no leader has hair dyed in a non-natural color. It would be nice to add some pastels to the map.
