Why doesn't -tab- work?
Here is another way (code taken from -codebook-) if you have more than 3,000
(Intercooled) or 12,000 rows (Stata/SE):
. webuse union,clear
(NLS Women 14-24 in 1968)
. tempvar tag
. bys id: gen byte `tag'= 1 if _n==1
(21766 missing values generated)
. count if `tag'==1 & !missing(id)
4434
. return list
scalars:
r(N) = 4434
