```Perhaps you want some aggregation
as well, or to it by groups. Some techniques are
shown by

. count if hmsa_r == 2
. local num = r(N)
. count if inlist(hmsa_r,1,2,3)
. local pc = 100 * `num' / r(N)
. di `pc'

That gives an overall percent.

. bysort group : egen num = sum(hmsa_r == 2)
. by group : egen den = sum(inlist(hmsa_r,1,2,3))
. gen pc = 100 * num / den
. egen tag = tag(group)
. tabdisp group if tag, cell(pc)

That gives percents within -group-.
