Here's somebody suggesting a shorter way: you can replace the first 6 lines in the code below with 1 line (that will execute much faster):

bysort id: gen count=_N

Until somebody else suggests a shorter way, one way to do it is the following:

gen count=.
levels id, local (levels)
foreach l of local levels{
count if id==`l'
replace count=r(N) if id==`l'
duplicates drop id count, force
tab count

I think that should work
