This map shows the proportion of worldwide Gross Domestic Product equalised in US$ in purchasing power parity that was produced there in 1500.
This map uses data by Maddison, A., 2003, The World Economy: Historical Statistics, original data shown in column B, missing data estimated from regional total estimates in original source where indicated or from regional average calculated from those countries for which data was originally estimated (“..” = not included in original).
We aim to map as complete data as possible and therefore estimate data for missing values. In some cases, missing data for very small territories is not used in the cartogram and that area is therefore omitted in the map.
Further notes on the data, as well as all modifications to the original data source are noted in our data sheets (ready to download soon)
