Pew Internet and American Life Project raised plenty of eyebrows in September with research showing that 24 percent of Americans use Twitter or similar status-updating services.
After redoing the questioning to focus on Twitter itself, Pew found that 8 percent of the U.S. is tweeting.
The researcher also found that Twitter skews to a younger, urban demographic and, interestingly, is twice as popular among African Americans and Hispanics as it is with whites. Fourteen percent of 18-29-year-olds said they used Twitter versus 7 percent of those 30-49, 6 percent of those 50-64 and 4 percent of respondents over 65. Racial breakdowns show an even bigger disparity, with 5 percent of whites saying they use it, 13 percent of black respondents and 18 percent of Hispanics.
Unsurprisingly, Twitter is more popular in urban areas, with 11 percent in cities using it versus 8 percent in the suburbs and 5 percent in rural locations.
Women are also more likely to tweet, with 10 percent using Twitter versus 7 percent of men.
That 8 percent of U.S. Internet users would put Twitter’s user figures at 14 million, taking into account comScore’s estimate of 175 million Web users in the U.S. Twitter, for its part, boasts much larger numbers: 175 million users, with 61 million in the U.S. alone. A Twitter spokesman said the service is adding 370,000 new accounts daily.
