Gapminder reacted fast after I pointed out a mistake in the U.S. Population map on their site. Hans Rosling, a Swedish professor of international health who became worldfamous overhight after a TED speech in 2006, wrote to thank me for my alert.
"We agree that it would have been best to show the native population, but we have not found any such time series. Gapminder only have the resources to display existing dataset and make them freely available."In another comment from Gapminder, Zhang writes that "we have changed the name of the indicator (US citizens), and also added some explanations in the tooltip bar, which could be seen when you hover your mouse on the indicator."
