Sysomos, the U.S. now accounts for about 50% of all active Twitter users. This is down sharply from 62% in June 2009. The share of Twitter users from Brazil, Indonesia and Germany, however, has grown significantly over the last six months.While Twitter's growth has slowed down in recent months, new data shows that the popular microblogging service has found a lot of new users outside of the United States. According to new data from social media analytics and monitoring firm
Brazil, Indonesia and Germany
Brazil now accounts for 8.8% of all Twitter users - up from just 2% in June. Indonesia's Twitter users now account for 2.5% of all users (up from 0.5%). The percentage of German users among all Twitter users is now 2.5%, up from 1.5% in the middle of last year.
Users from Brazil now represent Twitter's second most active population, followed by the U.K. (7.2%), Canada (4.35%) and Germany (2.49%).
Interestingly, the U.K. still leads Brazil when it comes to the number of total tweets contributed. Here the U.S. leads with 56.59% (down from 50.9% last year), followed by the U.K. (8.09%). Twitter's Brazilian population contributed 6.73% of all tweets.
Twitter's most active users can be found in New York City, London and Los Angeles. Twitter's hometown of San Francisco is home to the company's 10th most active group of users.
These numbers clearly indicate that Twitter saw significant growth outside the U.S. over the last six months. You can find Sysomos' full report here.
Nobody is Using Geotagging
Sysomos got this this data by analyzing the profiles of over 13 million unique Twitter users who were active between Oct. 16, 2009 and Dec. 16, 2009.
Given the recent interest in geotagging and geolocation services, we also asked Sysomos to look at the percentage of tweets that are currently being tagged trough Twitter's Geotagging API. While we didn't expect that large numbers of users were currently attaching location data to their tweets, we were surprised by how low this number currently is. Sysomos scanned 10 million tweets from Monday and Tuesday this week. Only 0.23% of these had been tagged using the Geotagging API.
Given that the API has only been available for a few month and that only a small number of Twitter clients currently supports this service, it doesn't come us a surprise that only a few users are currently using this service. This small number, however, also indicates that users aren't clamoring to tag their location to their tweets.
