Pew study reveals who uses Twitter most


If you're online, the chances are 1 in 5 that you're updating your Twitter or Facebook status, according to a new study by the Pew Internet and American Life Project. And if you're a female African-American college graduate making less than $30,000 a year and hauling around a mobile device, the study says you're probably tweeting more than anyone else.

The report is another indication of how researchers are trying to figure out who you are and what you're doing on social media. (The other day I took a look at a new Nielsen study that shoe-horned Americans into one of 66 demographic segments and then described how they use social networking sites. Major trends: Facebookers are more upscale than MySpacers; bloggers are more urban than rural.)

Pew found that among those who tweet:

  • Women (21 percent) tweet more than men (17 percent). 
  • African-Americans (26 percent) tweet more than whites (19 percent) and Hispanics (18 percent).
  • Those 18-29 years old (33 percent) are the heaviest tweeters. The lightest? Those aged 65 or older (4 percent).
  • College graduates (21 percent) out-tweet high school graduates (17 percent).
  • Folks making less than $30,000 a year tweet the most (22 percent). Those making $70,000 a year or more tweet the least (20 percent).
  • Mobile users are much more likely to tweet than folks chained to their desks, by a margin of 25-8 percent.
  • The median age of a Twitter user is 31. For MySpace it's 26. LinkedIn users have a median age of 39. Facebook "is graying a bit: the median age for this social network site is now 33."

Pew says it generated it results from telephone interviews conducted by Princeton Survey Research International between Aug. 18 and Sept. 14 among a sample of 2,253 adults, 18 and older. The margin of sampling error is plus or minus 2.7 percentage points.
