Highest paid public employees

The website Twisted Sifter has 40 maps that explain some aspect of our world. Some of them I've seen before, such as 7 regions of the world, each with a population of 1 billion. Here are some of the others.

* Economic center of gravity – In 1913 it was in Sweden. It has wandered near the North Pole until 2000, since then it has moved sharply towards China.

* The 22 countries that Britain has not invaded.

* Highest paid public employees in each state. In all but 11 states it is a football or basketball coach.

* If the world's population lived in once city – if that city was the density of New York the world's population would fit in Texas.

* Earthquakes since 1898.
