According to the first-ever survey reading from Pew Research that exclusively examines Twitter users, 8 percent of online adults said they use Twitter, with 2 percent doing so on a typical day. Since the survey showed that about 74 percent of American adults are Internet users, the Twitter universe apparently amounts to 6 percent of the entire U.S. adult population. 

Not surprisingly, the largest contingent comes from the age group of 18-29 year olds. About 14 percent of this group claim to be using Twitter. That figure drops in half for the 30-49 demographic. The study also found that minority Internet users are almost twice as likely to use Twitter as their white counterparts, and that same proportion exists for urban versus rural Internet users. 

Twitter users are nearly equally divided between those who check the site on a daily basis (or multiple times per day) and those who check the site infrequently or never. Just over one third of Twitter users check for material posted by others on a daily basis or multiple times per day, roughly comparable with the 41 percent who say they check the site less than every few weeks, or never do so at all. 

Surprisingly, the average video stream sourced via Twitter is viewed for two minutes and seven seconds. No other social network or search engine analyzed broke the two minute mark. Yahoo followed with an average Twitter viewing time of one minute and 54 seconds, closely trailed by Facebook with an average viewing time of one minute and 50 seconds. Search engines Google (1:27) and Bing (1:09) had significantly shorter average online video viewing times.
