Found this cool info-graphic inspired by the Olympic Rings logo that compares statistics across the 5 continents. Gustavo Sousa (the artist) left out the legend for each continent. I thought it was a clever move, if you really care about the information you’ll do your research and most likely you’ll actually remember it. 

I did my research and according to the statistical data it goes something like this:

Oceania: Blue

Europe: Black

America: Red

Africa: Yellow

Asia: Green 

…I think it’s something like that.
