Part of investing success is recognizing demographic trends, and riding the wave of economic freedom and growing middle class wealth to profits. The above graphs show the world's population by latitude and longitude. I find the longitude graph much more interesting than the latitude graph. It shows the potential impact of the large Asian and African populations on the world economy. While Africa suffers from a lack of economic freedom and is probably not fertile investing ground at this time, Asia is an entirely different story. Asia's populations dwarf that of the Western hemisphere and one can only imagine the economic potential of this area as the middle class grows and populations become wealthier and better educated.
