Which BO release we are talking about.
Search the BOB downloads for utilities on such a requirement.
Or do a search with keywords: number of users

Not sure about Older version. But in XI you can find in CMC>users. on top of the line you can see total number of users in your BO.

If you are on 6.x you can get this list by querying the repository tables (obj_m_actor? and you may need to reference a few others i believe, depending on what you need). There should be documentation on the BusObj support site that provides the database architecture for the 6.x repository that you will need to extract the information you need.
here is a sample that you can build off of to get a list of users.
Select distinct m_actor_c_name from obj_m_actor
where M_actor_n_type =16

Thats the one! 
It should give you everything you need to run queries directly off of the repository.
