Create and manage SharePoint groups

If you’re a site collection administrator or a site owner, you can create or delete SharePoint groups. By deciding which users are members of these groups, you can use groups to control access to your sites and content. By default, groups are created at the site collection level because the site collection is the default root of site permissions. You can also create a SharePoint group for a Subsite and add people into it there.
Note    You must be assigned a permission level that includes the Create Groups permission to create a group. To assign a permission level to a group, you must also be assigned Manage Permissions.
