Mapping London's 'Tube Tongues'
An interactive map shows what languages—apart from English—are most spoken at each underground stop.
Step out at the Oxford Circus stop in London and your ears are immediately assaulted by several different languages at once. That's understandable, considering Oxford street is usually quite crowded—tourists and Londoners alike buzz in and out of the shops and restaurants the street is known for.
One of the languages I heard most in that region was French. I thought this was because, in general, London has the most French nationals living there of any other city outside France. A more targeted review shows it's also because a lot of French speakers live in that area.
