I'm surprised so many languages seem to have been forgotten. In particular, there are two dots in Spain and one in France, which means that a few are missing (Occitan, Portuguese and Breton are missing). EDIT: The map linked in the article refers to papers as source, so it's not '57% of all languages' but '57% of all languages for which such a study exists'
