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-.
