Kids under 13 are currently banned from registering on Facebook, but Zuckerberg believes the restrictions - which are in force across the UK and American - should be lifted to enable children to experience the educational benefits of Facebook.
The site has more than 600 million users and claims it currently polices profiles to make sure young children are unable to register, although reports suggest that one in five nine to 12 year olds in the UK have a Facebook page.
Speaking at an innovation summit in schools in California, Mark Zuckerberg was asked whether he wanted the ban on under-13s lifted. He said:
'That will be a fight we take on at some point. My philosophy is that for education you need to start at a really, really young age. Because of the restrictions we haven't even begun this learning process. If they're lifted then we'd start to learn what works.'
Children's charities have said allowing under 13s on Facebook could raise the risk of cyber bullying and online dangers.
What do you think?
Do you allow your pre-teens on Facebook anyway, despite the age restriction?
Or do you think it is right that the site is for 13+ only?
