The map below shows the shifting location of the world’s economic center of gravity. It was compiled by McKinsey and reproduced by The Economist.
All is broadly as one might expect. In pre-industrial times, the world’s economic center of gravity was always basically triangulated between India, China, and the Roman Empire (later North-West Europe). By 1913, the US had became a significant world power, and in mid century it had drawn the center of gravity out into the North Atlantic. Since then the rise of the USSR, Japan, and then China, SE Asia, and India, started shifting the ball east and south at an accelerating pace. Today the speed of this transition is 140km per year. So there you have it: A cartographic representation of The Rise of the Rest.
By 2025, as shown on the map, the ball will be located somewhere in the Altai Mountains of Siberia. After that it will probably take a small dip south as India starts becoming much more prominent. Eventually however it will start going north and west again as the Arctic opens up and countries like Russia and Canada start growing much more rapidly as the century draws to a close. The cycle will retrace its ancient path.
Population of Africa, South America and Indonesia are so much larger that those of the future Artic that it will go south for a very long time
