We have updated the map in gapminder world. We removed all “former countries” and “ad-hoc” areas, but included all small countries and territies. We included even the smallest countries and territories, such as Pitcairn (where the mutineers of bounty settled) and Canada’s somewhat less known neighbour St.Pierre-et-Miquelon.
You find the map under the tab “map” in Gapminder World. You can also follow this link which takes you directly there, although it should be noted that the direct link is slower than normal since additional map-related data has to be loaded.
