New research suggests that nearly half of American teenagers say they use the Internet almost all the time. The results were based on a Pew public opinion study carried out from April 14 to May 4. The study contained 1,316 teens aged 13 to 17 years old. The research found that about 95 percent of American teens have smartphones.
The study also asked teens about their social media behavior. It found that the number of teens using Facebook has dropped to 32 percent, down from 71 percent in 2015. The research showed that teens have moved away from Facebook to spend time on the video sharing services YouTube and TikTok. About 95 percent of the teens said they use Google-owned YouTube, while 67 percent said they use TikTok.
About 62 percent of the teens said they use Instagram, which is owned by Facebook’s parent company Meta. About 59 percent said they use Snapchat. Less than one fourth of the teens said they use Twitter.
The research found that teen boys are more likely than teen girls to use YouTube, or the services Twitch and Reddit. Teen girls are more interested in using TikTok, Instagram and Snapchat. In addition, higher shares of black teens reported using TikTok, Twitter and WhatsApp compared to white teens.
About 54 percent of the teens questioned said it would be “somewhat hard” to give up social media, while 46 percent said it would be “somewhat easy”. About 25 percent of the teen boys said giving up social media would be “very easy”. But just 15 percent of the teen girls said the same.
