　　About six million people worldwide post to Twitter, producing some 650,000 new tweets daily. And one percent of these posts include geographic¹ locations. The combination of language and location has allowed scientists to calculate the dominant² language of any given region. They presented their work at the American Physical Society's March Meeting.

　　The researchers gained free access to a tenth of all tweets, which they ran through an automated³ language detector⁴. Throwing Twitter languages onto a map revealed highly accurate borders for European countries, a good proof of concept for the effort. On a much smaller scale, Twitter language geography reflected the small pockets of Korean and Russian concentrations within New York City.

　　The Twitter tracking method has its biases⁵. English is the dominant language of the internet, which skews the language distribution in bilingual cities like Montreal. And, obviously, the scientists can't analyze⁶ areas where people don't use Twitter. But overall, the study shows that Twitter can provide cheap and useful information. In other words, people tend to speak what they Tweet.
