Pew surveyed more than 3,400 U.S. Facebook users in May and June, and found that a whopping 44 percent of those ages 18 to 29 say they've deleted the app from their phone in the last year. Some of them may have reinstalled it later.
Overall, 26 percent of survey respondents say they deleted the app, while 42 percent have "taken a break" for several weeks or more, and 54 percent have adjusted their privacy settings.
The results don't necessarily spell dire news for the company as a whole. The survey measures only the core Facebook app, not Facebook-owned Instagram, WhatsApp and Messenger, all of which remain popular and offer a lot of room for revenue growth. In addition, it does not measure Facebook users outside the U.S., where growth has continued as North American usage has stalled.
