According to a February 12, 2009 report from the Pew Internet & American Life Project, some 11 percent of the U.S. adult population had used Twitter or similar micro-blog personal update services by December 2008. This marks a 22-percent, one-month leap in usage from November 2008.
“Overall, Twitter users engage with news and own technology at the same rates as other Internet users, but the ways in which they use the technology — to communicate, gather and share information — reveals their affinity for mobile, untethered and social opportunities for interaction,” the Pew project said in a release. “Moreover, Twitter as an application allows for and enhances these opportunities, so it is not so surprising that users would engage in these kinds of activities and also be drawn to an online application that expands those opportunities.”
“Twitter and similar services have been most avidly embraced by young adults,” Pew said. “Nearly one in five (19%) of online adults ages 18 and 24 have ever used Twitter and its ilk, as have 20% of online adults 25 to 34. Use of these services drops off steadily after age 35 with 10% of 35 to 44 year-olds and 5% of 45 to 54 year-olds using Twitter. The decline is even more stark among older Internet users; 4% of 55-64 year-olds and 2% of those 65 and older use Twitter.”
