The diversity of languages typed on Twitter by Eric Fischer.
Detail of Europe:
This map is enthralling to me. I’ve spent a considerable amount of time with the High-Res version, contemplating how the countries merge through their borders.
Belgium tweets in Dutch (cyan) and French (violet). Switzerland mainly in German (red), which seems to also dominate Central Europe. Poland almost gets lost there. Besides an apparent lack of Twitter’s popularity, there might be a colour coding issue. For me, it was unexpected to find that a large chunk of Austria seems to be tweeting in Italian (blue), just as several dots in the south of France.
On the other hand, you have territories that define their boundaries more discernibly, such as the Netherlands, Portugal or the Scandinavian countries. Catalan (lime green) deserves a special mention as it differentiates very conspicuously within the borders of northeaster Spain. The Balearic Islands acquire an interesting colour due to the fact that not only Catalan and Spanish mix but there is also an evident influence of German, French, and Italian tourists or expatriates. Here, multilingualism is the norm, not the exception.
This map was made last year. I’m revisiting it because I was hoping it would shed some light in the recent Ukranian language issue. Unfortunately, Ukrainian was not mapped. Only Russian (green), that goes well beyond Russia’s borders.
