Sysomos has updated their analysis of tweets by geography, and has found that the use of Twitter is becoming more widely distributed around the world. The company also found that almost no one is using the geo-location API tool that Twitter launched last August, with only 0.23% of all Tweets tagged with geo-location. Among the most significant differences was a surge in Brazil, which accounted for 8.8% of unique users, an increase of more than four-fold from 2% in June. Twitter users in Indonesia accounted for 2.4% of the population, compared with less than 0.5%, while Twitter users in Germany rose to 2.5% from 1.5%.
Meanwhile, the number of U.S. unique users was 50.8%, a sharp drop from 62.1% in June. This suggests that the use of Twitter outside the U.S. has experienced significant growth over the past six months.
When it comes to cities, London has the highest percentage of Twitter users, while New Yorkers contribute the highest percentage of overall tweets.
