Hi @juancarrion , 

You need to fetch data from tables and then filter based on need. 

Get the list of role(s) which contains this view_change role from table "sys_user_role_contains" 

Get the list of User who has this role, either direct or through group and inherited & inheritence count will explain that. You will get the Contained By  and Group both the count here.

-Thanks,
