How Economic Power Has Shifted Over The Past 200 Years

Over the last 200 years, economic leadership has shifted from China to the British Empire, then to the United States, and increasingly back toward Asia. The visualization incorporates the latest available data from the Maddison Project Database, the COLDAT Colonial Dates Dataset, and the IMF’s World Economic Outlook. All GDP figures are adjusted for purchasing power parity (PPP), accounting for differences in living costs and production across countries. American economic dominance was supported by high-value industries and the country’s central role in global finance, manufacturing, and trade. Their large populations and lower production costs give both countries greater weight when output is measured using purchasing power parity.
