A new Pew Report stated that 13% of online adults use Twitter, and half of Twitter users access the service on a cell phone. This is a significant increase from the 8% of online adults who said they were Twitter users the first time Pew asked about Twitter adoption in November 2010. Different groups a have varying adoption rates. The study found that 25% of online African Americans now use Twitter, 19% of Hispanics, compared with 9% of non-Hispanic whites to use the Pew terms.
There are age differences as well. As reported, 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 more pronounced among 25-34 year olds—Twitter use for this group roughly doubled between November 2010 and May 2011, from 9% to 19%. At the same time among the youngest adults (those ages 18-24) Twitter usage as stable at 16 – 18 %. Twitter use in the 55 -64 age group also doubled from 4% to 8% during this same time period. Even the over 65 age group went from 4% to 6%.
The new data is recent as the results are based on telephone interviews conducted by the Princeton Survey Research Associates International from April 26 to May 22, 2011, among a sample of 2,277 adults, age 18 and older. They had about a 12% response rate.
