In order to be eligible to sign up for Facebook, people must be 13 years of age or older.
The minimum age of 13 is a requirement in the Children’s Online Privacy Protection Act (COPPA) in the US.

Whilst clearly this is a US legislation international providers, such as Facebook, have adopted this standard as part of their global terms and conditions of use.
