Once I realized that the graph showed half the population was under age 10, I knew it could not be any of the gentrified countries listed, so that left Nigeria. Scary population graph.
I’d love to see one of China, to see if their population can be identified by a too-large “male” side.
The pop curve looked to me like one of an undeveloped country, so I picked Nigeria. I did consider the Netherlands since they have euthanasia. Missed the DOW chart and Google Glass. Got 91%.
