Back in January 2014, a report from iStrategyLabs ruffled the feathers of Facebook’s top executives as it indicated that teens and Facebook were beginning not to agree with each other with many deciding to leave the social media service.  Now, a new report from Frank N. Magid Associates Inc. has shown that indeed Facebook’s teen population is in serious decline.

According to the study, 88% of teenagers age 13 to 17 used Facebook.  This is a drop of 6% from their numbers just last year.  Although they still hold a vast majority of all teens using social media, this figure is quite substantial considering other social media services are seeing quite the opposite.  Twitter, for example, has seen a growth of 2% over the last year growing from 46% of teens to 48%.

Facebook’s trouble with teens is due in part to the belief that the site simply isn’t safe or trustworthy with only 9% believing the site to be safe.  That’s not the only problem for the social media giant.  The service is simply not fun for many teens with only 18% of teens rating it as an exciting platform to visit.   To compare, 40% of teens ranked Pinterest as fun demonstrating the work that needs to be done if Facebook hopes to reverse this trend with their services.

It’s not all bad news for Facebook, however.  The social media giant acquired Instagram for $1 billion in 2012 and the messaging app, Whatsapp, for $19 billion.  Instagram recently surpassed the 300 million active monthly user mark and both services are considered immensely popular with teens with many studies showing that younger users are leaving Facebook for these services.

Even with teens flocking to services already owned by Facebook this is still an alarming trend that likely has top level brass at Facebook worried.  The power of Facebook as a tool for marketing to teens is unmatched and executives must find ways to increase the trust of its leading brand with teens if it hopes to leverage that power with younger users using Facebook as a vital source of income for the social media service.
