Twitter doesn’t reflect real life.

The 22 percent of American adults who use the social media platform are younger, wealthier, more educated and more likely to identify as Democrats than the general population, according to the Pew Research Center study.

And within those users, about half are responsible for 80 percent of tweets. Meaning that most of the dialogue on the platform comes from only 2 percent of Americans.

Prolific tweeple are more likely to be women and to post regularly about politics, according to Pew.
