Why major social networks collect age but do not display it
<p>I have noticed this on various social networks that during registration user is asked to specify age, however created user profile does not display the age. </p>

<p>Users on social networks that provide the bio text field usually put their age into the bio section anyway.</p>

<p>Is it illegal to display age of users who are below 18? </p>

<p>This is the only explanation I can think of, since dating websites and dating social networks that are for adults only, always display the age alongside the users profile.</p>

<p>Many jurisdictions require parental consent to allow minors to sign up for social media. In the US the age is, I think, 13. They ask to ensure you are above that age.</p>
