In 2018, the number of Facebook users is expected to decline by 5.6% in the 12-17-year-old users group and by 5.8% in the 18-24-year-old users group. This year, less than half of USA internet users ages 12 to 17 will use Facebook on any device at least once a month, the forecast said.
An August eMarketer analysis suggested teens and tweens found Snapchat and Instagram more appealing for their visual content, while those still left on Facebook seemed to be less engaged with the platform.
Additionally, the number of users ages 12 to 17 and 18 to 24 will decrease by 5.6 per cent and 5.8 per cent, respectively.
Last month saw Facebook's US user numbers drop for the first time in its history, and now it looks like United Kingdom teens will abandon the site in 2018. Facebook requires members to be 13 to sign up, though many kids under that age access social media by having their parents start their account. But not all of those users are migrating to Instagram.
The research firm released Facebook usage estimates for 2018 on Monday, and expects that Facebook will lose about 2.1 million users in the US under the age of 25 this year. The number of users in the U.S. who stopped logging into Facebook doubles to 2.8 million if you factor in all users under the age of 25. EMarketer estimates that Instagram will add 1.6 million US users to Snapchat's 1.9 million users in 2018.
The statistics are equally true in the USA, where for the first time ever fewer than 50% of teenage internet users will log in to Facebook at least once a month.
Facebook's rival platform Snapchat was only launched in 2011 but is fast growing, and is set to add 1.9 million users in 2018.
Facebook's uncool status has been made fun of on Twitter for years.
Facebook originally managed to stem the tide of younger users abandoning its service by simply buying the product they were flocking to - Instagram. By comparison, Instagram (also owned by Facebook as of 2012) will record 104.7 million US users.
eMarketer has also stated that Snapchat will potentially gain from Facebook's loss, due to their new interactive features, and as what teens are expected to want, it's more novelty, therefore the number is predicted to increase this year. Children under ten are already on social media.
Facebook has known about their "teen-trouble" for a while and has worked hard to keep current by continuously offering new products and platforms that might appeal to younger users.
Of course, "that's the predicament Facebook is in", Williamson notes.
