And while people do take Facebook breaks, Internet users are logging in more frequently than ever, the study found.
Among other interesting tidbits:
— 59 percent of Facebook users said that the site is about as important to them as it was a year ago;
— 12 percent said Facebook is more important to them than it was a year ago and 28 percent said it has become less important.
— 8 percent says they took a break from Facebook because they were spending too much time using it.
— 69 percent said they plan to spend the same amount of time on Facebook in the coming year. Twenty-seven percent plan to spend less time on the site and 3 percent, more time.
Responding to the report, Facebook said that its growth and user engagement remains strong.
"As we announced last week, Facebook has grown daily active users across all regions, ending the year with more than 1 billion monthly active users, 618 million daily active users and 680 million people accessing Facebook from mobile devices," according to a company statement. "Our announcement came on the heels of independent analyst reports which concluded that Facebook is the most downloaded mobile app in the U.S., and that time spent on Facebook accounts for over 20 percent of all time spent on mobile apps in the US."
The Pew study of 1,006 U.S. adults was done in December. It has a margin of error of 3.6 percentage points.
