Most U.S. adults on Twitter post only rarely. But a small share of highly active users, most of whom are Democrats, produce the vast majority of tweets. The Center’s analysis finds that just 10% of users produced 92% of all tweets from U.S. adults since last November, and that 69% of these highly prolific users identify as Democrats or Democratic-leaning independents.

A number of factors contribute to this phenomenon. Previous Twitter analyses by the Center have found that the platform contains a larger share of Democrats than Republicans. And in addition to being more prevalent on the site in general, the 10% most active Democrats typically produce roughly twice as many tweets in a month (157) as the 10% most active Republicans (79).

Across both parties, those who use Twitter differ in several ways compared with non-users. For instance, Twitter-using Democrats and Republicans alike tend to be younger and have higher levels of educational attainment compared with members of each party who do not use the platform.
