Check out -groups- and -tabcount- from SSC. 

There was a write-up in 

Speaking Stata: Problems with tables, Part II. 
Stata Journal 3(4): 420--439 (2003) 

You need, however, to be very careful with terminology
in this connection: when you refer to missing values here you 
mean values that are not present, not at all the
same thing!
