A very interesting map infographic from National Geographic that shows where and how the population of 7 billion lives. The map shows population density; the brightest points are the highest densities. Each country is colored according to its average annual gross national income per capita, using categories established by the World Bank.
The most amazing thing for me on this infographic is how World population and per capita income have been shown in co-relation with things like Life expectancy, years of education, literacy rate, fertility rate, new migration rate, phone subscriptions, cars, carbon dioxide emissions etc.
Here is one of the correlations with world population and per capita income and you can see more on National Geographic’s website by clicking on various tabs of the infographic.
