The true size of Africa

Kai Krause came up with this awesome map to help in the “fight against rampant Immappancy,” i.e. insufficient geographic knowledge:

A survey with random American schoolkids let them guess the population and land area of their country. Not entirely unexpected, but still rather unsettling, the majority chose “1-2″ billion” and “largest in the world,” respectively.

Even with Asian and European college students, geographical estimates were often off by factors of 2-3. This is partly due to the highly distorted nature of the predominantly used mapping projections (such as Mercator).

YFrog “corrected” Krause’s map by using equal area projected countries (whatever that means). And then Information Is Beautiful paired the map with these other geographical comparisons.
