NEW YORK >> Too much drama, boredom and scads of irrelevant information are just some of the reasons Facebook users give for taking a break from the world’s biggest social networking site for weeks at a time, according to a new study.

A report from the Pew Research Center’s Internet and American Life Project found that some 61 percent of Facebook users had taken a hiatus of at least several weeks for myriad reasons, whether they were weary from an onslaught of gossip, or for the more pious, the arrival of Lent.

Yet the use of Facebook, whether constant or not, is pervasive in America.

Of the American adults who use the Internet, 67 percent are on Facebook, Pew found. That compares with 20 percent who use LinkedIn and 16 percent who are on Twitter.

But users do come and go, some temporarily, and some for good. Seven percent of Internet users said they used Facebook at one point but no longer do. By its own count, Facebook Inc. has 1.06 billion users worldwide who check in at least once a month. This includes millions of duplicate and fake accounts. More than 150 million users are in the U.S.

The largest slice of users, 20 percent, said that they were simply too busy with their own lives to follow the constant stream of status updates, George Takei quotes and baby photos.

Privacy and security concerns, which have received plenty of media coverage, were low on the list. Only 4 percent of people gave these reasons, combined with concerns about ads and spam, as their “Facebook vacation” motivation.

Lee Rainie, director of the Internet and American Life Project, said privacy is more of a big policy question that people do not concern themselves with day-by-day. Rather, people are contemplating how they spend their time and allocate their attention.

“People are making interesting calibrations and recalibrations” about how they spend their time and about the worth of constantly staying connected to friends, family and others online, Rainie said.

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 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 said 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.
