A gated community is a type of neighborhood that has a gate, or wall, around the entire neighborhood. This gate can either be locked or open, but it prevents people from entering who don't live there or who aren't allowed in. The purpose of the gate is to provide extra security for the people who live inside. The gate keeps out people who are not allowed in, and that can help protect the residents from criminals. Most gated communities also have security guards, cameras, and other measures to help keep people safe.
