Pew Internet - Twitter Update 2011

The Pew Internet and American Life Project recently released its updated statistics on Twitter use.  The report found that as of May 2011, 13% of online adults use the status update service Twitter. That represents a significant increase from the 8% of online adults who identified themselves as Twitter users the first time they were asked a “stand-alone” question about Twitter adoption in November 2010.

Twitter usage by those ages 25-44 has grown significantly since late 2010
Although young adults continue to have relatively high rates of Twitter usage, the number of 30-49 year olds who use the service has doubled since late 2010—from 7% of such users in November to 14% in May 2011. This growth trend is especially pronounced among 25-34 year olds—Twitter use for this cohort roughly doubled between November 2010 and May 2011, from 9% to 19%—although growth in Twitter use among internet users ages 35-44 was notable as well (from 8% in late 2010 to 14% in spring 2011). By contrast, Twitter adoption over the same time period was stable among the youngest adults (those ages 18-24) who were the most likely to use the service in the first survey.

These findings come from national survey findings from a poll conducted on landline and cell phones, in English and Spanish, between April 26 and May 22, 2011 among 2,277 adults (age 18 and older). The margin of error among the internet users is +/- 3.7 percentage points.  To view the entire survey from Pew Internet, please visit here.
