Sophie Bushwick, senior editor at Popular Science, gives a comprehensive report on what information Facebook gathers from users and gives to advertisers. She says that the platform not just keeps track of your age and location, but also knows your home value, ethnic affinity, field of study, and so much more. She gives tips to control what Facebook knows about you. If you don't want to delete your page entirely, there is an option to click "do not share with advertisers" under certain information fields. She discusses how much people are willing to sacrifice their privacy for social media. She doesn't believe people will change what they share, mainly because a lot of them don't even realize how much data Facebook is collecting.
