The study reveals other differences between Twitter and Facebook users in the ways they consume news. On Twitter, 85% of users read the news on mobile devices “at least sometimes,” a larger percentage than Facebook users (64%).

Last week, Pew published a study that revealed 30% of Americans get news on Facebook — most of whom aren’t there for that purpose. The study on Twitter released on Monday does not address whether Twitter users are accidental news consumers, too.

Twitter news consumers are also younger and more educated than their Facebook counterparts. 45% of them are between the ages of 18 and 29 (for Facebook, only 34% are in that age range), and only 2% are 65 or older (compared to 7% on Facebook).

The survey is accompanied by a series of analyses on Twitter conversations related to news events like the acquittal of George Zimmerman, the man accused of killing Trayvon Martin, and the Supreme Court ruling on same-sex marriage. These studies reveal that Twitter is a more popular platform for breaking news than sharing opinions, and that sentiments shift very rapidly.

The Pew report is based on a survey of 5,000 U.S. adults (735 Twitter users and 3,268 Facebook users) and analysis of Twitter conversations around news events over the past two years.
