Description

The ability to see group population is handful for Confluence administrators.
It would be helpful if the Groups admin page had the number of users associated with each group.
As an use case, this would help on administering the users counting towards the license.
This functionality is already implemented in Jira as shown in the image below:

Workaround

Run a query in the database to count the number of users in a specific group.

SELECT COUNT(DISTINCT lower_user_name) 
FROM cwd_user
WHERE id IN (SELECT m.child_user_id FROM cwd_membership AS m
JOIN cwd_group AS g ON m.parent_id = g.id
WHERE g.group_name = '<group_name>');

Side Notes

This request is different from the one in CONFSERVER-54271.
