z/OS is a server and as such, user counts are often irrelevant. TSO, IMS, Unix 
and CICS can have associated userids which is 1 person affect by 1 userid. On 
the other hand, credit card transaction exceed 100M per day but it's not 100M 
people affected because people often use their credit card multiple times in a 
day. You will never know how many users of DB2 are affected when SAP is 
responsible for managing users. Unless you know every aspect of your z/OS, you 
can't say how many people (not users) are affected.
