Source: Gallup, Sachs and Mellinger via "The distribution of world income," James Hamilton, Econbrowser,January 13, 2007.The graph was calculated from GDP per capita multiplied by population density. Some of what it shows corresponds well with our intuition -- Western Europe and the norht-eastern part of the United States are centers of production. Less intuitive to me is the intensity of economic production on the China coast and the Indian piedmont.
The importance of access to the sea stands out, doesn't it!
I suppose all of us who try to tamper with this distribution (development professionals) should be forced to look at this map often. Too bad it uses a projection that does not maintain area, but rather enlarges lands far from the equator.
