Average measure with age calculation measure

[NumeroENAP]

Hi, 

I want my table to show the average age of each categories (ex : by gender), but I don't want to create a column. So, I created a first measure : 

Age = DATEDIFF(ALL(PERS[date]);TODAY();DAY)

After that, I created a second measure, but it seems that I'm in the wrong, because it doesn't work :

AgeAVG = AVERAGEX(ALL(ID);[Age])

Thank you

Hi @NumeroENAP 

Please show a sample of your tables/data model. Otherwise we waste time. Have a look at these tips for getting your question answered quickly.  Try this measure:

Measure =
AVERAGEX ( VALUES ( Table1[ID] ), DATEDIFF ( Table1[Date of birth], TODAY (), YEAR ) )

Please mark the question solved when done and consider giving kudos if posts are helpful.
