During my journeys, I have noticed that travelers who come from relatively small countries that have their own language often can speak foreign languages very well. Perhaps the explanation is that no one else outside the borders of the country can speak their language, so they have to learn foreign languages. Language institute EF has measured how well people across the world understand English, and the results seem to reflect my small country theory to a certain extent.
Dark blue and dark grey indicate countries with high English skills (EF). Read the story “The best countries to travel in for tourists who only speak English”
