This map shows the proportion of gross tonnage (ship’s overall internal volume) in the world registered there in 2016.
This map uses data by U.S. Department of Transportation Maritime Administration (last accessed March 2018). 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.
All modification to the original data source are noted in our data sheets.Download data file
