Proportion of World Economy projected in the Millennium Ecosystem Assessment scenarios (Tg – TechnoGarden, go-Global Orchestration, am- Adapting Mosaic, and OS-Order From Strength). Compared to yesterday’s post of Maddison’s data, which is in Purchasing Power Parity, this graph estimates the size of the world economy using 1995 exchange rates, which under estimates the purchasing power of poor countries – particularly the Chinese economy. Consquently, this graph and yesterday’s graph do not match in 2000.

This graph shows Asia passing Western Europe + North America & Oceania in about 75 years, later in the slow economic growth world of Order From Strength. If purchasing power is used then crossing date would be earlier.
