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.
- 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."
