U.S. adult Twitter users are younger and more likely to be Democrats than the general public. Most users rarely tweet, but the most prolific 10% create 80% of tweets from adult U.S. users.
Pew Research Center conducted a nationally representative survey of 2,791 U.S. adult Twitter users who were willing to share their Twitter handles.
From the article,
The analysis indicates that the 22% of American adults who use Twitter are representative of the broader population in certain ways, but not others. Twitter users are younger, more likely to identify as Democrats, more highly educated and have higher incomes than U.S. adults overall. Twitter users also differ from the broader population on some key social issues. For instance, Twitter users are somewhat more likely to say that immigrants strengthen rather than weaken the country and to see evidence of racial and gender-based inequalities in society. But on other subjects, the views of Twitter users are not dramatically different from those expressed by all U.S. adults. The median user tweets just twice each month, but a small cohort of extremely active Twitter users posts with much greater regularity. As a result, much of the content posted by Americans on Twitter reflects a small number of authors. The 10% of users who are most active in terms of tweeting are responsible for 80% of all tweets created by U.S. users.
The research also showed that the most common tweeters are much more likely to be women and more likely to say they regularly tweet about politics. However, there are only modest differences in many attitudes between those who tweet frequently and those who do not.
