Facebook Users chartFacebook won't lose its standing in the social media pantheon anytime soon. More people than ever — more than half of the U.S. population, in fact — are expected to use the social network this year, according to a recent social network usage forecast by digital market research company eMarketer.

For the first time, nearly 163 million Americans — or 50.3 percent of the population — will log onto Facebook at least once a month in 2016, up from 49.3 percent last year, according to eMarketer.

Photo swapping site Instagram — also owned by Facebook — will see almost 90 million U.S. users this year, which accounts for nearly a third of the population, and Twitter will surpass 55 million users in 2016, representing nearly 18 percent of the U.S. population, according to eMarketer.

Not surprisingly, mobile use may account for a sizeable swath of Facebook's continued popularity. According to eMarketer, 86 percent of all U.S. Facebook users will access the network via mobile devices this year, and more than half of all U.S. mobile users — 52.9 percent — will use their devices to log on to the network at least once a month.

The eMarketer forecast predicts that Facebook will garner nearly $10 billion in ad spends this year as a result of its considerable user base, accounting for nearly 75 percent of all U.S. social network ad revenues. Mobile is expected to make up more than 80 percent of those revenues this year.

The forecast also predicts that Facebook will remain the top social media network “through at least 2020.”
