Is there a way to determine how many confluence users had access to a particular confluence space, for example as of December 2015?

[Kailash Subramanian]

Basically, the project team wants to find out the growth in terms of how many users had access to a particular space as of certain date/month. We do have "Space Activity" feature enabled but that's not what they are looking for. Please let me know if there is a way to get this stats from confluence application or directly from the database. We use MySQL and the confluence version is 5.2.5. 

Thanks in advance for any help provided.

Not unless you've got a backup from that time, or you have been logging all access changes somehow.
