What is the average age for kids to open a social media account? The last study done on the subject was back in 2016 and the average age was twelve and a half. Summer is a big time for kids to ask to open their own accounts to keep in touch with friends while school is out, so parents of kids around this age should be prepared. Psychologists say that around 12 years old is when kids have the capability to follow your rules and to understand that those rules are set in place for their safety. Sit down and talk about how to keep personal information – age, where they go to school, address, phone numbers, credit card numbers and more – private, and explore together the platform your child is interested in, including the privacy settings that can be used.
