This visual has been posted on multiple development and recreational sites recently. Although I first overlooked it as fairly elementary, the graphic is effective and straightforward when expressing the divergence of factors such as literacy rates and living conditions around the world. My favorite statistic, and that which I believe should demand more attention, is at the very bottom.
If the world were 100 people, 48 would live on less than $2 a day, and 1 out of 2 children would live in poverty.
