ROCHESTER, NY: Fewer than half of US consumers (48%) have a Facebook or MySpace account, and only 5% use Twitter, according to a poll released this month by Harris Interactive.
The survey found that social networking use varies depending on age. Of adults ages 18 to 34 years old, 74% use either MySpace or Facebook, but only 24% of those 55 or older do so.
To further break out those age groups, the survey found that 47% of consumers ages 35 to 44 have social networking accounts; and 41% of those ages 45 to 54 do. Frequency of use of social networking services also varies by age, with nearly three in 10 consumers ages 18 to 34 updating their accounts at least once a day, but only 3% of those 55 and older doing so.
Twitter use is steadier across age demographics than use of social networking sites, with 8% of consumers ages 18 to 34 using the service, and 7% of those ages 35 to 44 doing so. Four percent of people ages 45 to 54 tweet regularly, while only 1% of those 55 and older use the microblogging service.
Social media use also varies slightly by education, according to the survey. Of those consumers who use Facebook or MySpace, more than half are college graduates.
The Harris Poll interviewed 2,220 adults on March 31 and April 1.
