It is unfortunately not possible to determine if a user was active during a specific year and then report this information. Lansweeper will only give back the date when the user was created but not scan if the user was enabled/disabled. The Lastscanned field will also not help in this situation as this field will only give back the date when the tblADObjects table was modified.
We did add a report below that will give back a count of all the AD users created per year.
Select Top 1000000 DatePart(yyyy, tblADusers.whenChanged) As Year,
Count(tblADusers.ADUserID) As Users
From tblADusers
Group By DatePart(yyyy, tblADusers.whenChanged)
