Age Average

I have to calculate the average age in a group.
What is the best way to calculate the average age where I have the
individual's birth date?
Thanks in advance!SELECT AVG(DATEDIFF(DAY,birth_date,CURRENT_TIME
STAMP))/365.25
FROM YourTable
GROUP BY ...

select datediff(mm, yourDOB, getdate())/12.0

More information please...
Post your table DDL and more detailed specs of what you're trying to
accomplish. SQL has an AVG() function to calculate averages based on a
set of data.

birthdate. That could be more useful in some circumstances.
