The share of Americans who use Facebook is on the rise: 79% of online adults use the platform, more than double the share that uses Twitter, Pinterest, Instagram or LinkedIn.
While Facebook remains the most popular social media site, other platforms — like LinkedIn, Pinterest, Instagram and Twitter — saw higher rates of growth over the past year. In 2014, 52% of online adults used two or more social media sites, up from 42% in 2013.
Youth are sharing more personal information on their profiles than in the past. They choose private settings for Facebook, but share with large networks of friends.
