think you can try -alorenz- command from ssc. If I am not mistaken that commad does what you need.

So it does take a little bit of programming - but I agree that the use of -tabstat- with the -by()- option is very convenient.
Many thanks, it works perfectly!

This would be safer
gen decile = 10 if !missing(age)
